public static byte[] Compress( 
   byte[] buffer,
   int offset,
   int count,
   CompressionLevel level
)

Parameters

buffer

The array of bytes to compress. A maximum of count bytes are taken from this array and compressed.

offset

The byte offset in buffer at which to begin taking the data to compress.

count

The maximum number of bytes to be taken from buffer.

level

A Xceed.Compression.CompressionLevel value representing the compression level to use.

Return Value

The Xceed.Compression.CompressionMethod.Deflated compression method will always be used.

If the data to compress is not a byte array, it will need to be converted into a byte array before it can be compressed. This can be done, in the case of a string, using the System.Text.Encoding.GetBytes(System.Char[]) method of the System.Text.Encoding class.

The compression level only applies to the Deflated and Deflated64 compression methods.  It does not apply to the BZip2, BWT, or PPMd compression methods.
