Examples

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;
}

public 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 = (FtpWebRequest)WebRequest.Create (serverUri);
    request.KeepAlive = true;
    request.Method = WebRequestMethods.Ftp.MakeDirectory;
    FtpWebResponse response = (FtpWebResponse)request.GetResponse ();
    Console.WriteLine ("Status: {0}", response.StatusDescription);
    return true;
}

Remarks

The FtpStatusCode enumeration defines the values returned in the StatusCode property.
