GZipStream.Write Method

Writes compressed bytes to the underlying stream from the specified byte array.

Namespace:  System.IO.Compression
Assembly:  System (in System.dll)

abstract Write : 
        array:byte[] * 
        offset:int * 
        count:int -> unit 
override Write : 
        array:byte[] * 
        offset:int * 
        count:int -> unit 


Type: System.Byte[]
The buffer that contains the data to compress.
Type: System.Int32
The byte offset in array at which the compressed bytes will be placed.
Type: System.Int32
The maximum number of compressed bytes to write.


The write operation cannot be performed because the stream is closed.

The write might not occur immediately but is buffered until the buffer size is reached or until the Flush or Close method is called.

The following code example shows how to use the GZipStream class to compress and decompress a file.
