DeflateStream Constructor (Stream, CompressionMode, Boolean)
Initializes a new instance of the DeflateStream class by using the specified stream and compression mode, and optionally leaves the stream open.
Assembly: System (in System.dll)
- Type: System.IO.Stream
The stream to compress or decompress.
- Type: System.IO.Compression.CompressionMode
One of the enumeration values that indicates whether to compress or decompress the stream.
By default, DeflateStream owns the underlying stream, so closing the stream 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 DeflateStream class is created with the mode parameter equal to Compress, header information is inserted immediately. If no further action occurs, the stream appears as a valid, empty, compressed file.
Using the DeflateStream class to compress a file larger than 4 GB raises an exception.
