GZipStream Constructor (Stream, CompressionMode)
Updated: January 2012
Assembly: System (in System.dll)
By default, GZipStream owns the underlying stream, so closing the stream parameter also closes the underlying stream. Note that the state of the underlying stream can affect the usability of the stream. Also, no explicit checks are performed, so no additional exceptions are thrown when the new instance is created.
If an instance of the GZipStream class is created with the mode parameter equal to Compress and no further action occurs, the stream will appear as a valid, empty compressed file.
The GZipStream class might not be able to decompress data that results in over 8 GB of uncompressed data.
