      Returns checksum types supported by the server.


      public override FileChecksumType[] GetSupportedChecksumTypes()

      Return Value

      Checksum types supported by the server.


      Shows how to use GetFileChecksum and CalculateLocalChecksum methods to get checksum returned from the server and calculate checksum of a local file.
