'Declaration
 
Public Overloads Shared Function Compress( _
   ByVal buffer() As Byte, _
   ByVal level As CompressionLevel _
) As Byte()

'Usage
 
Dim buffer() As Byte
Dim level As CompressionLevel
Dim value() As Byte
 
value = GZipCompressedStream.Compress(buffer, level)

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

Parameters

buffer

The array of bytes to compress.

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.
