Represents SSPI exception. Initializes new instance of TemplateException with serialized data. Serialized object data. Contextual information. Represents SSPI mechanism. SSPI authentication methods (NTLM, Kerberos, Negotiate) can work in two modes: 1. The user specifies their credentials explicitly (like other authentication methods work), and authentication token is created from them. 2. Integrated Windows Authentication (IWA). The authentication token is created by Windows from the credentials of the currently logged Windows user. The application never deals with the account password. IWA mode provides increased security and spares the end user from entering their credentials. IWA, however, cannot be used when the currently logged Windows user is not an interactive user. In web applications, you often deal with system users (like NETWORK SERVICE, ASPNET, etc). To be able to use IWA in an ASP.NET application, the application itself must run under the context of an interactive user (<authentication mode="Windows"/> in web.config). Also, the user from whose context the authentication token is constructed, must have a valid mailbox on the e-mail server. This is important as even if the given user is registered in the Active Directory and can log in the domain, it does not necessarily mean that the system has already provisioned their mailbox. NTLM mechanism. Kerberos mechanism. Kerberos is the technological successor to NTLM. Negotiate mechanism. Selects Kerberos and if not available, NTLM protocol. The pBuffer parameter contains a pointer to a SecPkgContext_Sizes structure. Queries the sizes of the structures used in the per-message functions.

Represents flag used by IMAP protocol to mark email messages. Static fields represent most common, system flags. You can use and to set or remove a flag. Exchange 2007 and 2010 do not support custom flags (keywords). Gets \ALL flag. It repesents all messages in the mailbox. Gets \SEEN flag. Message has been read. Gets \NEW flag. It represents messages that have the flag set but not the flag. This is functionally equivalent to "(\RECENT \UNSEEN)". Gets \RECENT flag (don't confuse it with ). Message is "recently" arrived in this mailbox. This session is the first session to have been notified about this message; if the session is read-write, subsequent sessions will not see \Recent set for this message. This flag can not be altered by the client. Gets \OLD flag. It represents messages that do not have the flag set. This is functionally equivalent to "NOT \RECENT" (as opposed to "NOT \NEW").

"\AllMail" flag used by XLIST command. "\Important" flag used by XLIST command. "\Spam" flag used by XLIST command. "\Starred" flag used by XLIST command. This folder presents all messages in the user's message store (\All). Implementations MAY omit some messages, such as, perhaps, those in \Trash and \Junk. When this special use is supported, it is almost certain to represent a virtual folder. This folder is used to archive messages (\Archive). The meaning of an "archival" folder is server-dependent; typically, it will be used to get messages out of the inbox, or otherwise keep them out of the user's way, while still making them accessible. This folder is used to hold draft messages - typically, messages that are being composed but have not yet been sent (\Drafts). In some server implementations, this might be a virtual folder, containing messages from other folders that are marked with the message flag. Alternatively, this might just be advice that a client put drafts here. This folder presents all messages marked in some way as "important" (\Flagged). When this special use is supported, it is likely to represent a virtual folder collecting messages (from other folders) that are marked with the "\Flagged" message flag. This folder is where messages deemed to be junk mail are held (\Junk). Some server implementations might put messages here automatically. Alternatively, this might just be advice to a client-side spam filter. This folder is used to hold copies of messages that have been sent (\Sent). Some server implementations might put messages here automatically. Alternatively, this might just be advice that a client save sent messages here. This folder is used to hold messages that have been deleted or marked for deletion (\Trash). In some server implementations, this might be a virtual folder, containing messages from other folders. The presence of this attribute indicates that the folder has child folders that are accessible to the user (\HasChildren). RFC 3348 The presence of this attribute indicates that the folder has NO child mailboxes that are accessible to the user. If a folder has the attribute, the attribute is redundant and SHOULD be omitted. (\HasNoChildren). RFC 3348 It is not possible for any child levels of hierarchy to exist under this name; no child levels exist now and none can be created in the future (\Noinferiors). This flag also implies . It is not possible to use this name as a selectable folder (\Noselect). Indicates that a folder name does not refer to an existing mailbox (\NonExistent). This flag also implies . Indicates that a folder is remote folder. (\Remote). Indicates that a folder is subscribed. (\Subscribed). The folder has been marked as "interesting" by the server; The folder probably contains messages that have been added since the last time the folder was selected -or- has a non-zero RECENT message count. (\Marked). The folder has been marked as "uninteresting" by the server; The folder does not contain any additional messages since the last time the folder was selected -or- has a zero RECENT message count.

The next unique identifier value is the predicted value that will be assigned to a new message in the folder (mailbox). Unless the unique identifier validity () also changes , the next unique identifier value MUST NOT change unless new messages are added to the mailbox; and the next unique identifier value MUST change whenever new messages are added to the mailbox, even if those new messages are subsequently deleted. The next unique identifier value is intended to provide a means for a client to determine whether any messages have been delivered to the mailbox since the previous time it checked this value. Gets the message sequence number of the first unseen message in the folder (OK [UNSEEN <n>]) If it's null client can not make any assumptions about the first unseen message, and needs to issue a with if it wants to find it.

Represents expressions that can be used by methods. To join several sort criteria use . Reverses specified sorter. Descending order is used. Note: REVERSE only reverses a single criterion, and does not affect the implicit "sequence number" sort criterion if all other criteria are identical. Consequently, a sort of REVERSE SUBJECT is not the same as a reverse ordering of a SUBJECT sort. This can be avoided by use of additional criteria, e.g., SUBJECT DATE vs. REVERSE SUBJECT REVERSE DATE. In general, however, it's better (and faster, if the client has a "reverse current ordering" command) to reverse the results in the client instead of issuing a new SORT. Sort criteria New sorter.

The next unique identifier value is intended to provide a means for a client to determine whether any messages have been delivered to the mailbox since the previous time it checked this value. UIDVALIDITY: The unique identifier validity value. Any change of unique identifiers between sessions MUST be detectable using the change of UIDVALIDITY. If unique identifiers from an earlier session fail to persist in this session, the UIDVALIDITY value MUST be greater than the one used in the earlier session.

Represemtes THREAD=ORDEREDSUBJECT threading method. The ORDEREDSUBJECT threading algorithm is also referred to as "poor man's threading". The searched messages are sorted by base subject and then by the sent date. The messages are then split into separate threads, with each thread containing messages with the same base subject text. Finally, the threads are sorted by the sent date of the first message in the thread. The top level or "root" in ORDEREDSUBJECT threading contains the first message of every thread. All messages in the root are siblings of each other. The second message of a thread is the child of the first message, and subsequent messages of the thread are siblings of the second message and hence children of the message at the root. Hence, there are no grandchildren in ORDEREDSUBJECT threading. Children in ORDEREDSUBJECT threading do not have descendants. Client implementations SHOULD treat descendants of a child in a server response as being siblings of that child. Represemtes THREAD=REFERENCES threading method. The REFERENCES threading algorithm threads the searched messages by grouping them together in parent/child relationships based on which messages are replies to others. The parent/child relationships are built using two methods: reconstructing a message's ancestry using the references contained within it; and checking the original (not base) subject of a message to see if it is a reply to (or forward of) another message.

Computes a CRC-32. The CRC-32 algorithm is parameterized - you can set the polynomial and enable or disable bit reversal. This can be used for GZIP, BZip2, or ZIP. This type is used internally by DotNetZip; it is generally not used directly by applications wishing to create, read, or manipulate zip archive files. Indicates the total number of bytes applied to the CRC. Indicates the current CRC for all blocks slurped in. Returns the CRC32 for the specified stream.

This is a computation defined by PKzip for PKZIP 2.0 (weak) encryption. The word to start with. The byte to combine it with. The CRC-ized result. Update the value for the running CRC32 using the given block of bytes. This is useful when using the CRC32() class in a Stream. block of bytes to slurp starting point in the block how many bytes within the block to slurp Process one byte in the CRC. the byte to include into the CRC . Process a run of N identical bytes into the CRC. This method serves as an optimization for updating the CRC when a run of identical bytes is found. Rather than passing in a buffer of length n, containing all identical bytes b, this method accepts the byte value and the length of the (virtual) buffer - the length of the run. the byte to include into the CRC. the number of times that byte should be repeated. Combines the given CRC32 value with the current running total. This is useful when using a divide-and-conquer approach to calculating a CRC. Multiple threads can each calculate a CRC32 on a segment of the data, and then combine the individual CRC32 values at the end. the crc value to be combined with this one the length of data the CRC value was calculated on Create an instance of the CRC32 class using the default settings: no bit reversal, and a polynomial of 0xEDB88320. Create an instance of the CRC32 class, specifying whether to reverse data bits or not. specify true if the instance should reverse data bits. In the CRC-32 used by BZip2, the bits are reversed. Therefore if you want a CRC32 with compatibility with BZip2, you should pass true here. In the CRC-32 used by GZIP and PKZIP, the bits are not reversed; Therefore if you want a CRC32 with compatibility with those, you should pass false. Create an instance of the CRC32 class, specifying the polynomial and whether to reverse data bits or not. The polynomial to use for the CRC, expressed in the reversed (LSB) format: the highest ordered bit in the polynomial value is the coefficient of the 0th power; the second-highest order bit is the coefficient of the 1 power, and so on. Expressed this way, the polynomial for the CRC-32C used in IEEE 802.3, is 0xEDB88320. specify true if the instance should reverse data bits. In the CRC-32 used by BZip2, the bits are reversed. Therefore if you want a CRC32 with compatibility with BZip2, you should pass true here for the reverseBits parameter. In the CRC-32 used by GZIP and PKZIP, the bits are not reversed; Therefore if you want a CRC32 with compatibility with those, you should pass false for the reverseBits parameter. Reset the CRC-32 class - clear the CRC "remainder register." Use this when employing a single instance of this class to compute multiple, distinct CRCs on multiple, distinct data blocks. A Stream that calculates a CRC32 (a checksum) on all bytes read, or on all bytes written. This class can be used to verify the CRC of a ZipEntry when reading from a stream, or to calculate a CRC when writing to a stream. The stream should be used to either read, or write, but not both. If you intermix reads and writes, the results are not defined. This class is intended primarily for use internally by the DotNetZip library. The default constructor.

This method always throws N/A N/A N/A This method always throws N/A Closes the stream. A class for compressing and decompressing streams using the Deflate algorithm. The DeflateStream is a Decorator on a . It adds DEFLATE compression or decompression to any stream. Using this stream, applications can compress or decompress data via stream Read and Write operations. Either compresssion or decompression can occur through either reading or writing. The compression format used is DEFLATE, which is documented in IETF RFC 1951, "DEFLATE Compressed Data Format Specification version 1.3.". This class is similar to , except that ZlibStream adds the RFC 1950 - ZLIB framing bytes to a compressed stream when compressing, or expects the RFC1950 framing bytes when decompressing. The DeflateStream does not. Create a DeflateStream using the specified CompressionMode. When mode is CompressionMode.Compress, the DeflateStream will use the default compression level. The "captive" stream will be closed when the DeflateStream is closed. This example uses a DeflateStream to compress data from a file, and writes the compressed data to another file. using (System.IO.Stream input = System.IO.File.OpenRead(fileToCompress)) { using (var raw = System.IO.File.Create(fileToCompress + ".deflated")) { using (Stream compressor = new DeflateStream(raw, CompressionMode.Compress)) { byte[] buffer = new byte[WORKING_BUFFER_SIZE]; int n; while ((n= input.Read(buffer, 0, buffer.Length)) != 0) { compressor.Write(buffer, 0, n); } } } } Using input As Stream = File.OpenRead(fileToCompress) Using raw As FileStream = File.Create(fileToCompress & ".deflated") Using compressor As Stream = New DeflateStream(raw, CompressionMode.Compress) Dim buffer As Byte() = New Byte(4096) {} Dim n As Integer = -1 Do While (n <> 0) If (n > 0) Then compressor.Write(buffer, 0, n) End If n = input.Read(buffer, 0, buffer.Length) Loop End Using End Using End Using The stream which will be read or written.

Indicates whether the DeflateStream will compress or decompress. A tuning knob to trade speed for effectiveness. Create a DeflateStream using the specified CompressionMode, and explicitly specify whether the stream should be left open after Deflation or Inflation. This constructor allows the application to request that the captive stream remain open after the deflation or inflation occurs. By default, after Close() is called on the stream, the captive stream is also closed. In some cases this is not desired, for example if the stream is a memory stream that will be re-read after compression. Specify true for the parameter to leave the stream open. The DeflateStream will use the default compression level. See the other overloads of this constructor for example code. The stream which will be read or written. This is called the "captive" stream in other places in this documentation. Indicates whether the DeflateStream will compress or decompress. true if the application would like the stream to remain open after inflation/deflation. Create a DeflateStream using the specified CompressionMode and the specified CompressionLevel, and explicitly specify whether the stream should be left open after Deflation or Inflation. When mode is CompressionMode.Decompress, the level parameter is ignored. This constructor allows the application to request that the captive stream remain open after the deflation or inflation occurs. By default, after Close() is called on the stream, the captive stream is also closed. In some cases this is not desired, for example if the stream is a that will be re-read after compression. Specify true for the parameter to leave the stream open. This example shows how to use a DeflateStream to compress data from a file, and store the compressed data into another file. using (var output = System.IO.File.Create(fileToCompress + ".deflated")) { using (System.IO.Stream input = System.IO.File.OpenRead(fileToCompress)) { using (Stream compressor = new DeflateStream(output, CompressionMode.Compress, CompressionLevel.BestCompression, true)) { byte[] buffer = new byte[WORKING_BUFFER_SIZE]; int n= -1; while (n != 0) { if (n > 0) compressor.Write(buffer, 0, n); n= input.Read(buffer, 0, buffer.Length); } } } // can write additional data to the output stream here } Using output As FileStream = File.Create(fileToCompress & ".deflated") Using input As Stream = File.OpenRead(fileToCompress) Using compressor As Stream = New DeflateStream(output, CompressionMode.Compress, CompressionLevel.BestCompression, True) Dim buffer As Byte() = New Byte(4096) {} Dim n As Integer = -1 Do While (n <> 0) If (n > 0) Then compressor.Write(buffer, 0, n) End If n = input.Read(buffer, 0, buffer.Length) Loop End Using End Using ' can write additional data to the output stream here. End Using The stream which will be read or written. Indicates whether the DeflateStream will compress or decompress. true if the application would like the stream to remain open after inflation/deflation. A tuning knob to trade speed for effectiveness. This property sets the flush behavior on the stream. See the ZLIB documentation for the meaning of the flush behavior. The size of the working buffer for the compression codec. The working buffer is used for all stream operations. The default size is 1024 bytes. The minimum size is 128 bytes. You may get better performance with a larger buffer. Then again, you might not. You would have to test it. Set this before the first call to Read() or Write() on the stream. If you try to set it afterwards, it will throw. The ZLIB strategy to be used during compression. By tweaking this parameter, you may be able to optimize the compression for data with particular characteristics. Returns the total number of bytes input so far. Returns the total number of bytes output so far. Dispose the stream. This may or may not result in a Close() call on the captive stream. See the constructors that have a leaveOpen parameter for more information. Application code won't call this code directly. This method may be invoked in two distinct scenarios. If disposing == true, the method has been called directly or indirectly by a user's code, for example via the public Dispose() method. In this case, both managed and unmanaged resources can be referenced and disposed. If disposing == false, the method has been called by the runtime from inside the object finalizer and this method should not reference other objects; in that case only unmanaged resources must be referenced or disposed. true if the Dispose method was invoked by user code. Indicates whether the stream can be read. The return value depends on whether the captive stream supports reading. Indicates whether the stream supports Seek operations. Always returns false. Indicates whether the stream can be written. The return value depends on whether the captive stream supports writing. Flush the stream. Reading this property always throws a . The position of the stream pointer. Setting this property always throws a . Reading will return the total bytes written out, if used in writing, or the total bytes read in, if used in reading. The count may refer to compressed bytes or uncompressed bytes, depending on how you've used the stream. Read data from the stream. If you wish to use the DeflateStream to compress data while reading, you can create a DeflateStream with CompressionMode.Compress, providing an uncompressed data stream. Then call Read() on that DeflateStream, and the data read will be compressed as you read. If you wish to use the DeflateStream to decompress data while reading, you can create a DeflateStream with CompressionMode.Decompress, providing a readable compressed data stream. Then call Read() on that DeflateStream, and the data read will be decompressed as you read. A DeflateStream can be used for Read() or Write(), but not both. The buffer into which the read data should be placed. the offset within that data array to put the first byte read. the number of bytes to read. the number of bytes actually read Calling this method always throws a . this is irrelevant, since it will always throw! this is irrelevant, since it will always throw! irrelevant! Calling this method always throws a . this is irrelevant, since it will always throw! Write data to the stream. If you wish to use the DeflateStream to compress data while writing, you can create a DeflateStream with CompressionMode.Compress, and a writable output stream. Then call Write() on that DeflateStream, providing uncompressed data as input. The data sent to the output stream will be the compressed form of the data written. If you wish to use the DeflateStream to decompress data while writing, you can create a DeflateStream with CompressionMode.Decompress, and a writable output stream. Then call Write() on that stream, providing previously compressed data. The data sent to the output stream will be the decompressed form of the data written. A DeflateStream can be used for Read() or Write(), but not both. The buffer holding data to write to the stream. the offset within that data array to find the first byte to write. the number of bytes to write.

DeflateStream.CompressBuffer(byte[]) DeflateStream.UncompressString(byte[]) GZipStream.UncompressBuffer(byte[]) ZlibStream.UncompressBuffer(byte[]) A buffer containing data that has been compressed with DEFLATE. The data in uncompressed form A class for compressing and decompressing GZIP streams. The GZipStream is a Decorator on a . It adds GZIP compression or decompression to any stream. Like the System.IO.Compression.GZipStream in the .NET Base Class Library, the Ionic.Zlib.GZipStream can compress while writing, or decompress while reading, but not vice versa. The compression method used is GZIP, which is documented in IETF RFC 1952, "GZIP file format specification version 4.3". A GZipStream can be used to decompress data (through Read()) or to compress data (through Write()), but not both. If you wish to use the GZipStream to compress data, you must wrap it around a write-able stream. As you call Write() on the GZipStream, the data will be compressed into the GZIP format. If you want to decompress data, you must wrap the GZipStream around a readable stream that contains an IETF RFC 1952-compliant stream. The data will be decompressed as you call Read() on the GZipStream. Though the GZIP format allows data from multiple files to be concatenated together, this stream handles only a single segment of GZIP format, typically representing a single file. This class is similar to and . ZlibStream handles RFC1950-compliant streams. handles RFC1951-compliant streams. This class handles RFC1952-compliant streams. The comment on the GZIP stream. The GZIP format allows for each file to optionally have an associated comment stored with the file. The comment is encoded with the ISO-8859-1 code page. To include a comment in a GZIP stream you create, set this property before calling Write() for the first time on the GZipStream. When using GZipStream to decompress, you can retrieve this property after the first call to Read(). If no comment has been set in the GZIP bytestream, the Comment property will return null (Nothing in VB). The FileName for the GZIP stream. The GZIP format optionally allows each file to have an associated filename. When compressing data (through Write()), set this FileName before calling Write() the first time on the GZipStream. The actual filename is encoded into the GZIP bytestream with the ISO-8859-1 code page, according to RFC 1952. It is the application's responsibility to insure that the FileName can be encoded and decoded correctly with this code page. When decompressing (through Read()), you can retrieve this value any time after the first Read(). In the case where there was no filename encoded into the GZIP bytestream, the property will return null (Nothing in VB). The last modified time for the GZIP stream. GZIP allows the storage of a last modified time with each GZIP entry. When compressing data, you can set this before the first call to Write(). When decompressing, you can retrieve this value any time after the first call to Read(). The CRC on the GZIP stream. This is used for internal error checking. You probably don't need to look at this property. Create a GZipStream using the specified CompressionMode. When mode is CompressionMode.Compress, the GZipStream will use the default compression level. As noted in the class documentation, the CompressionMode (Compress or Decompress) also establishes the "direction" of the stream. A GZipStream with CompressionMode.Compress works only through Write(). A GZipStream with CompressionMode.Decompress works only through Read(). This example shows how to use a GZipStream to compress data. using (System.IO.Stream input = System.IO.File.OpenRead(fileToCompress)) { using (var raw = System.IO.File.Create(outputFile)) { using (Stream compressor = new GZipStream(raw, CompressionMode.Compress)) { byte[] buffer = new byte[WORKING_BUFFER_SIZE]; int n; while ((n= input.Read(buffer, 0, buffer.Length)) != 0) { compressor.Write(buffer, 0, n); } } } } Dim outputFile As String = (fileToCompress & ".compressed") Using input As Stream = File.OpenRead(fileToCompress) Using raw As FileStream = File.Create(outputFile) Using compressor As Stream = New GZipStream(raw, CompressionMode.Compress) Dim buffer As Byte() = New Byte(4096) {} Dim n As Integer = -1 Do While (n <> 0) If (n > 0) Then compressor.Write(buffer, 0, n) End If n = input.Read(buffer, 0, buffer.Length) Loop End Using End Using End Using This example shows how to use a GZipStream to uncompress a file. private void GunZipFile(string filename) { if (!filename.EndsWith(".gz)) throw new ArgumentException("filename"); var DecompressedFile = filename.Substring(0,filename.Length-3); byte[] working = new byte[WORKING_BUFFER_SIZE]; int n= 1; using (System.IO.Stream input = System.IO.File.OpenRead(filename)) { using (Stream decompressor= new Ionic.Zlib.GZipStream(input, CompressionMode.Decompress, true)) { using (var output = System.IO.File.Create(DecompressedFile)) { while (n !=0) { n= decompressor.Read(working, 0, working.Length); if (n > 0) { output.Write(working, 0, n); } } } } } } Private Sub GunZipFile(ByVal filename as String) If Not (filename.EndsWith(".gz)) Then Throw New ArgumentException("filename") End If Dim DecompressedFile as String = filename.Substring(0,filename.Length-3) Dim working(WORKING_BUFFER_SIZE) as Byte Dim n As Integer = 1 Using input As Stream = File.OpenRead(filename) Using decompressor As Stream = new Ionic.Zlib.GZipStream(input, CompressionMode.Decompress, True) Using output As Stream = File.Create(UncompressedFile) Do n= decompressor.Read(working, 0, working.Length) If n > 0 Then output.Write(working, 0, n) End IF Loop While (n > 0) End Using End Using End Using End Sub The stream which will be read or written. Indicates whether the GZipStream will compress or decompress. Create a GZipStream using the specified CompressionMode and the specified CompressionLevel.

Indicates whether the GZipStream will compress or decompress. A tuning knob to trade speed for effectiveness. Create a GZipStream using the specified CompressionMode, and explicitly specify whether the stream should be left open after Deflation or Inflation. This constructor allows the application to request that the captive stream remain open after the deflation or inflation occurs. By default, after Close() is called on the stream, the captive stream is also closed. In some cases this is not desired, for example if the stream is a memory stream that will be re-read after compressed data has been written to it. Specify true for the parameter to leave the stream open. The (Compress or Decompress) also establishes the "direction" of the stream. A GZipStream with CompressionMode.Compress works only through Write(). A GZipStream with CompressionMode.Decompress works only through Read(). The GZipStream will use the default compression level. If you want to specify the compression level, see . See the other overloads of this constructor for example code. The stream which will be read or written. This is called the "captive" stream in other places in this documentation. Indicates whether the GZipStream will compress or decompress. true if the application would like the base stream to remain open after inflation/deflation. Create a GZipStream using the specified CompressionMode and the specified CompressionLevel, and explicitly specify whether the stream should be left open after Deflation or Inflation. This constructor allows the application to request that the captive stream remain open after the deflation or inflation occurs. By default, after Close() is called on the stream, the captive stream is also closed. In some cases this is not desired, for example if the stream is a memory stream that will be re-read after compressed data has been written to it. Specify true for the parameter to leave the stream open. As noted in the class documentation, the CompressionMode (Compress or Decompress) also establishes the "direction" of the stream. A GZipStream with CompressionMode.Compress works only through Write(). A GZipStream with CompressionMode.Decompress works only through Read(). This example shows how to use a GZipStream to compress data. using (System.IO.Stream input = System.IO.File.OpenRead(fileToCompress)) { using (var raw = System.IO.File.Create(outputFile)) { using (Stream compressor = new GZipStream(raw, CompressionMode.Compress, CompressionLevel.BestCompression, true)) { byte[] buffer = new byte[WORKING_BUFFER_SIZE]; int n; while ((n= input.Read(buffer, 0, buffer.Length)) != 0) { compressor.Write(buffer, 0, n); } } } } Dim outputFile As String = (fileToCompress & ".compressed") Using input As Stream = File.OpenRead(fileToCompress) Using raw As FileStream = File.Create(outputFile) Using compressor As Stream = New GZipStream(raw, CompressionMode.Compress, CompressionLevel.BestCompression, True) Dim buffer As Byte() = New Byte(4096) {} Dim n As Integer = -1 Do While (n <> 0) If (n > 0) Then compressor.Write(buffer, 0, n) End If n = input.Read(buffer, 0, buffer.Length) Loop End Using End Using End Using The stream which will be read or written. Indicates whether the GZipStream will compress or decompress. true if the application would like the stream to remain open after inflation/deflation. A tuning knob to trade speed for effectiveness. This property sets the flush behavior on the stream. The size of the working buffer for the compression codec. The working buffer is used for all stream operations. The default size is 1024 bytes. The minimum size is 128 bytes. You may get better performance with a larger buffer. Then again, you might not. You would have to test it. Set this before the first call to Read() or Write() on the stream. If you try to set it afterwards, it will throw. Returns the total number of bytes input so far. Returns the total number of bytes output so far. Dispose the stream. This may or may not result in a Close() call on the captive stream. See the constructors that have a leaveOpen parameter for more information. This method may be invoked in two distinct scenarios. If disposing == true, the method has been called directly or indirectly by a user's code, for example via the public Dispose() method. In this case, both managed and unmanaged resources can be referenced and disposed. If disposing == false, the method has been called by the runtime from inside the object finalizer and this method should not reference other objects; in that case only unmanaged resources must be referenced or disposed. indicates whether the Dispose method was invoked by user code. Indicates whether the stream can be read. The return value depends on whether the captive stream supports reading. Indicates whether the stream supports Seek operations. Always returns false. Indicates whether the stream can be written. The return value depends on whether the captive stream supports writing. Flush the stream. Reading this property always throws a . The position of the stream pointer. Setting this property always throws a . Reading will return the total bytes written out, if used in writing, or the total bytes read in, if used in reading. The count may refer to compressed bytes or uncompressed bytes, depending on how you've used the stream. Read and decompress data from the source stream. With a GZipStream, decompression is done through reading. byte[] working = new byte[WORKING_BUFFER_SIZE]; using (System.IO.Stream input = System.IO.File.OpenRead(_CompressedFile)) { using (Stream decompressor= new Ionic.Zlib.GZipStream(input, CompressionMode.Decompress, true)) { using (var output = System.IO.File.Create(_DecompressedFile)) { int n; while ((n= decompressor.Read(working, 0, working.Length)) !=0) { output.Write(working, 0, n); } } } } The buffer into which the decompressed data should be placed. the offset within that data array to put the first byte read. the number of bytes to read. the number of bytes actually read Calling this method always throws a . irrelevant; it will always throw! irrelevant; it will always throw! irrelevant! Calling this method always throws a . irrelevant; this method will always throw! Write data to the stream. If you wish to use the GZipStream to compress data while writing, you can create a GZipStream with CompressionMode.Compress, and a writable output stream. Then call Write() on that GZipStream, providing uncompressed data as input. The data sent to the output stream will be the compressed form of the data written. A GZipStream can be used for Read() or Write(), but not both. Writing implies compression. Reading implies decompression. The buffer holding data to write to the stream. the offset within that data array to find the first byte to write. the number of bytes to write. Compress a string into a byte array using GZip. Uncompress it with . A string to compress. The string will first be encoded using UTF8, then compressed. The string in compressed form Compress a byte array into a new byte array using GZip. Uncompress it with . A buffer to compress. The data in compressed form Uncompress a GZip'ed byte array into a single string. A buffer containing GZIP-compressed data. The uncompressed string Uncompress a GZip'ed byte array into a byte array. A buffer containing data that has been compressed with GZip. The data in uncompressed form Map from a distance to a distance code. No side effects. _dist_code[256] and _dist_code[257] are never used. Describes how to flush the current deflate operation. The different FlushType values are useful when using a Deflate in a streaming application. No flush at all. Closes the current block, but doesn't flush it to the output. Used internally only in hypothetical scenarios. This was supposed to be removed by Zlib, but it is still in use in some edge cases. Use this during compression to specify that all pending output should be flushed to the output buffer and the output should be aligned on a byte boundary. You might use this in a streaming communication scenario, so that the decompressor can get all input data available so far. When using this with a ZlibCodec, AvailableBytesIn will be zero after the call if enough output space has been provided before the call. Flushing will degrade compression and so it should be used only when necessary. Use this during compression to specify that all output should be flushed, as with FlushType.Sync, but also, the compression state should be reset so that decompression can restart from this point if previous compressed data has been damaged or if random access is desired. Using FlushType.Full too often can significantly degrade the compression. Signals the end of the compression/decompression stream. The compression level to be used when using a DeflateStream or ZlibStream with CompressionMode.Compress. None means that the data will be simply stored, with no change at all. If you are producing ZIPs for use on Mac OSX, be aware that archives produced with CompressionLevel.None cannot be opened with the default zip reader. Use a different CompressionLevel. Same as None. The fastest but least effective compression. A synonym for BestSpeed. A little slower, but better, than level 1. A little slower, but better, than level 2. A little slower, but better, than level 3. A little slower than level 4, but with better compression. The default compression level, with a good balance of speed and compression efficiency. A synonym for Default. Pretty good compression! Better compression than Level7! The "best" compression, where best means greatest reduction in size of the input data stream. This is also the slowest compression. A synonym for BestCompression. Describes options for how the compression algorithm is executed. Different strategies work better on different sorts of data. The strategy parameter can affect the compression ratio and the speed of compression but not the correctness of the compresssion. The default strategy is probably the best for normal data. The Filtered strategy is intended to be used most effectively with data produced by a filter or predictor. By this definition, filtered data consists mostly of small values with a somewhat random distribution. In this case, the compression algorithm is tuned to compress them better. The effect of Filtered is to force more Huffman coding and less string matching; it is a half-step between Default and HuffmanOnly. Using HuffmanOnly will force the compressor to do Huffman encoding only, with no string matching. An enum to specify the direction of transcoding - whether to compress or decompress. Used to specify that the stream should compress the data. Used to specify that the stream should decompress the data. A general purpose exception class for exceptions in the Zlib library. The ZlibException class captures exception information generated by the Zlib library. This ctor collects a message attached to the exception. the message for the exception. Performs an unsigned bitwise right shift with the specified number Number to operate on Ammount of bits to shift The resulting number from the shift operation Reads a number of characters from the current source TextReader and writes the data to the target array at the specified index. The source TextReader to read from Contains the array of characteres read from the source TextReader. The starting index of the target array. The maximum number of characters to read from the source TextReader. The number of characters read. The number will be less than or equal to count depending on the data available in the source TextReader. Returns -1 if the end of the stream is reached. Computes an Adler-32 checksum. The Adler checksum is similar to a CRC checksum, but faster to compute, though less reliable. It is used in producing RFC1950 compressed streams. The Adler checksum is a required part of the "ZLIB" standard. Applications will almost never need to use this class directly. Calculates the Adler32 checksum. This is used within ZLIB. You probably don't need to use this directly. To compute an Adler32 checksum on a byte array: var adler = Adler.Adler32(0, null, 0, 0); adler = Adler.Adler32(adler, buffer, index, length); Encoder and Decoder for ZLIB and DEFLATE (IETF RFC1950 and RFC1951). This class compresses and decompresses data according to the Deflate algorithm and optionally, the ZLIB format, as documented in RFC 1950 - ZLIB and RFC 1951 - DEFLATE. The buffer from which data is taken. An index into the InputBuffer array, indicating where to start reading. The number of bytes available in the InputBuffer, starting at NextIn. Generally you should set this to InputBuffer.Length before the first Inflate() or Deflate() call. The class will update this number as calls to Inflate/Deflate are made. Total number of bytes read so far, through all calls to Inflate()/Deflate(). Buffer to store output data. An index into the OutputBuffer array, indicating where to start writing. The number of bytes available in the OutputBuffer, starting at NextOut. Generally you should set this to OutputBuffer.Length before the first Inflate() or Deflate() call. The class will update this number as calls to Inflate/Deflate are made. Total number of bytes written to the output so far, through all calls to Inflate()/Deflate(). used for diagnostics, when something goes wrong! The compression level to use in this codec. Useful only in compression mode. The number of Window Bits to use. This gauges the size of the sliding window, and hence the compression effectiveness as well as memory consumption. It's best to just leave this setting alone if you don't know what it is. The maximum value is 15 bits, which implies a 32k window. The compression strategy to use. This is only effective in compression. The theory offered by ZLIB is that different strategies could potentially produce significant differences in compression behavior for different data sets. Unfortunately I don't have any good recommendations for how to set it differently. When I tested changing the strategy I got minimally different compression performance. It's best to leave this property alone if you don't have a good feel for it. Or, you may want to produce a test harness that runs through the different strategy options and evaluates them on different file types. If you do that, let me know your results. The Adler32 checksum on the data transferred through the codec so far. You probably don't need to look at this. Create a ZlibCodec. If you use this default constructor, you will later have to explicitly call InitializeInflate() or InitializeDeflate() before using the ZlibCodec to compress or decompress. Create a ZlibCodec that either compresses or decompresses. Indicates whether the codec should compress (deflate) or decompress (inflate). Initialize the inflation state. It is not necessary to call this before using the ZlibCodec to inflate data; It is implicitly called when you call the constructor. Z_OK if everything goes well. Initialize the inflation state with an explicit flag to govern the handling of RFC1950 header bytes. By default, the ZLIB header defined in RFC 1950 is expected. If you want to read a zlib stream you should specify true for expectRfc1950Header. If you have a deflate stream, you will want to specify false. It is only necessary to invoke this initializer explicitly if you want to specify false. whether to expect an RFC1950 header byte pair when reading the stream of data to be inflated.

Z_OK if everything goes well. Ends an inflation session. Call this after successively calling Inflate(). This will cause all buffers to be flushed. After calling this you cannot call Inflate() without a intervening call to one of the InitializeInflate() overloads. Z_OK if everything goes well. I don't know what this does! Z_OK if everything goes well. Initialize the ZlibCodec for deflation operation.

The size of the working buffer used in the ZlibCodec class. Defaults to 8192 bytes. The minimum size of the working buffer used in the ZlibCodec class. Currently it is 128 bytes. Represents a Zlib stream for compression or decompression. The ZlibStream is a Decorator on a . It adds ZLIB compression or decompression to any stream. Using this stream, applications can compress or decompress data via stream Read() and Write() operations. Either compresssion or decompression can occur through either reading or writing. The compression format used is ZLIB, which is documented in IETF RFC 1950, "ZLIB Compressed Data Format Specification version 3.3". This implementation of ZLIB always uses DEFLATE as the compression method. (see IETF RFC 1951, "DEFLATE Compressed Data Format Specification version 1.3.") The ZLIB format allows for varying compression methods, window sizes, and dictionaries. This implementation always uses the DEFLATE compression method, a preset dictionary, and 15 window bits by default. This class is similar to , except that it adds the RFC1950 header and trailer bytes to a compressed stream when compressing, or expects the RFC1950 header and trailer bytes when decompressing.

If you wish to use the ZlibStream to decompress data while reading, you can create a ZlibStream with CompressionMode.Decompress, providing a readable compressed data stream. Then call Read() on that ZlibStream, and the data will be decompressed as it is read. A ZlibStream can be used for Read() or Write(), but not both. The buffer into which the read data should be placed. the offset within that data array to put the first byte read. the number of bytes to read. the number of bytes read Calling this method always throws a . The offset to seek to.... IF THIS METHOD ACTUALLY DID ANYTHING. The reference specifying how to apply the offset.... IF THIS METHOD ACTUALLY DID ANYTHING. nothing. This method always throws. Calling this method always throws a . The new value for the stream length.... IF THIS METHOD ACTUALLY DID ANYTHING. Write data to the stream. If you wish to use the ZlibStream to compress data while writing, you can create a ZlibStream with CompressionMode.Compress, and a writable output stream. Then call Write() on that ZlibStream, providing uncompressed data as input. The data sent to the output stream will be the compressed form of the data written. If you wish to use the ZlibStream to decompress data while writing, you can create a ZlibStream with CompressionMode.Decompress, and a writable output stream. Then call Write() on that stream, providing previously compressed data. The data sent to the output stream will be the decompressed form of the data written. A ZlibStream can be used for Read() or Write(), but not both. The buffer holding data to write to the stream. the offset within that data array to find the first byte to write. the number of bytes to write. Compress a string into a byte array using ZLIB.
