   if ( serverUri->Scheme != Uri::UriSchemeFtp )

      return false;
   }

   // Get the object used to communicate with the server.
   FtpWebRequest^ request = dynamic_cast<FtpWebRequest^>(WebRequest::Create( serverUri ));
   request->Method = WebRequestMethods::Ftp::MakeDirectory;
   FtpWebResponse^ response = dynamic_cast<FtpWebResponse^>(request->GetResponse());
   Console::WriteLine( "Status: {0}", response->StatusDescription );
   return true;
}
public static bool MakeDirectoryOnServer (Uri serverUri)
{

    FtpWebRequest request = (FtpWebRequest)WebRequest.Create (serverUri);
