Initializes a new instance of the GZipStream class by using the specified stream and compression level, and optionally leaves the stream open. Gets the Type of the current instance.

They are not intelligible when renderedand may also cause problems when transmitted over a network due to byte ordering, for instance. Write buffer, 0, buffer. Close Close Close Close. Returns a string that represents the current object. The format can be readily implemented in a manner not covered by patents. CompressionMode is Compress and CanWrite is false.
