    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
    '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.
