Description

The CompressionMethod property allows you to specify which compression or decompression algorithm will be used by the library. You must assign a Compression Method object to this property.

This property is read-only except when it belongs to the XceedStandardCompressionFormat object, because that format is the only one that supports settable/variable compression methods. The others are predefined to use either Deflate or BZip2 .

Data type

A Compression Method object

Possible values
 

Value	Description
XceedDeflateCompressionMethod	Use the Deflate compression algorithm.
XceedDeflate64CompressionMethod	Use the Deflate64 compression algorithm
XceedBWTCompressionMethod	Use the BZip2 compression algorithm.
XceedStoreCompressionMethod	No compression. Stores data in uncompressed format.

Default value

XceedDeflateCompressionMethod for the XceedStandardCompressionFormat. For other Compression Format objects, see their descriptions to find out what compression algorithm they use.

Applicable methods

Compress, Decompress, ProcessFile, ReadFile, WriteFile
