GzipCompressionStream Class

Namespace: Rebex.IO.Compression.Streams

Assembly: Rebex.Zip.dll (version 7.0.9147)

Provides a stream that uses RFC 1952 - GZIP implementation to compress data. If opened for writing it compresses specified data and writes the compressed data into an underlying stream. If opened for reading it reads an uncompressed data from the underlying stream and returns a compressed data. Unlike similar class present in .NET Framework 2.0, this one actually makes it possible to use Flush when compressing data to make sure all data written to the stream have been written into the underlying stream as well.

Methods

Name	Description
Dispose(Boolean)	Closes the underlying stream. Inherited from CompressionStream.
Flush()	Causes any buffered data to be written to the underlying stream. Inherited from CompressionStream.
Read(Byte[], Int32, Int32)	Reads data from the underlying stream, compressing them during the process. Inherited from CompressionStream.
Seek(Int64, SeekOrigin)	This method is not supported by the CompressionStream class. Inherited from CompressionStream.
