For additional information about FTP server status codes, see RFC 959, "File Transfer Protocol," Section 4.2, "FTP Replies," available at http://www.rfc-editor.org.

The following code example sends an FTP request to make a new directory on an FTP server and checks the status code returned in the response.

static bool MakeDirectoryOnServer( Uri^ serverUri )
{
   // The serverUri should start with the ftp:// scheme. 
   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;
}
