Provides a stream that uses specified compressed data format 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.
