'Usage
 
Dim inner As Stream

Dim method As CompressionMethod

Dim level As CompressionLevel

Dim encryptionPassword As String

 

Dim instance As New XceedCompressedStreamEx(inner, method, level, encryptionPassword)

public XceedCompressedStreamEx( 

   Stream inner,

   CompressionMethod method,

   CompressionLevel level,

   string encryptionPassword

)

Parameters

inner

The stream to write to and read from.

method

A Xceed.Compression.CompressionMethod value representing the compression method to use.

level

A Xceed.Compression.CompressionLevel value representing the compression level to use.

encryptionPassword

The encryption password to use.

If the inner stream is readonly, the compressed stream will read the header at construction.

The Stored compression method is not supported. The compression level only applies to the Deflated and Deflated64 compression methods.  It does not apply to the BZip2, BWT, or PPMd compression methods.

The PPMd algorithm uses a custom memory management system called SubAllocator. In a zip file, the memory size the SubAllocator uses is defined in the WinZip PPMd header for the compressed file and this header's value is used when decompressing the data. In general, WinZip uses 64Mb. Since the algorithm used was not optimized from the original PPMd version I revision 1, the SubAllocator initially requires the total amount of memory specified in the PPMd compressor. This means you must have at least 64 free Mb of RAM when using this compression method.

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
