   // This application doesn't want they proxy to be used so it sets
   // the global proxy to an empy proxy.
   IWebProxy^ myProxy = GlobalProxySelection::GetEmptyWebProxy();
   
   // Get the response.
   WebResponse^ response = request->GetResponse();
   
   // Display the response to the console.
   Stream^ stream = response->GetResponseStream();
   StreamReader^ reader = gcnew StreamReader( stream );
   Console::WriteLine( reader->ReadToEnd() );
   
   // Clean up.
   reader->Close();
   stream->Close();
   response->Close();
   return 0;

            IWebProxy myProxy = GlobalProxySelection.GetEmptyWebProxy();
            GlobalProxySelection.Select = myProxy;
            // Get the response.

Remarques

La GetEmptyWebProxy méthode retourne une instance vide IWebProxy pour indiquer qu’aucun proxy n’est utilisé pour accéder à une ressource Internet.

Au lieu d’appeler la GetEmptyWebProxy méthode, vous pouvez affecter null à des membres tels que la WebClient.Proxy propriété , qui spécifie le proxy qui communique avec les serveurs distants pour le compte de l’objet WebClient .
