XceedCompressedStreamEx Class

In This Topic

Represents a pass-through stream that reads and writes Xceed formatted compressed data. Use this class to decompress or compress data compatible with the ActiveX Xceed Zip Compression Library (XceedCompression object).

Syntax

Visual Basic
C#

'Declaration
 
Public Class XceedCompressedStreamEx 
   Inherits XceedCompressedStream
   Implements System.IDisposable

'Usage
 
Dim instance As XceedCompressedStreamEx

public class XceedCompressedStreamEx : XceedCompressedStream, System.IDisposable

Remarks

Compression is applied to data being written to the stream, and decompression is performed when data is read from the stream.

By default, closing the XceedCompressedStream will also close the inner stream. This behavior can be modified by setting the FormattedCompressedStream.Transient property to true.

To make sure that the header and footer are written, you can call FormattedCompressedStream.Write with 0 bytes. If neither FormattedCompressedStream.Write nor FormattedCompressedStream.Read has been called, the XceedCompressedStream does not know if it is reading or writing. The Adler32 of this class is initialized to 1 rather than 0 as with the XceedCompressedStream class.
