C# Class ICSharpCode.SharpZipLib.GZip.GZipOutputStream

This filter stream is used to compress a stream into a "GZIP" stream. The "GZIP" format is described in RFC 1952. author of the original java version : John Leuner

Public Methods

Method	Description
Finish ( ) : void	Finish compression and write any footer information required to stream
GZipOutputStream ( Stream baseOutputStream ) : System	Creates a GzipOutputStream with the default buffer size
GZipOutputStream ( Stream baseOutputStream, int size ) : System	Creates a GZipOutputStream with the specified buffer size
GetLevel ( ) : int	Get the current compression level.
SetLevel ( int level ) : void	Sets the active compression level (1-9). The new level will be activated immediately.
Write ( byte buffer, int offset, int count ) : void	Write given buffer to output updating crc

Protected Methods

Method	Description
Dispose ( bool disposing ) : void	Writes remaining compressed output data to the output stream and closes it.
WriteHeader ( ) : void
