Il n'y a pas de flux de réponse.

L’exemple suivant montre comment utiliser GetResponseStream pour retourner l’instance Stream utilisée pour lire la réponse du serveur.
// Creates an HttpWebRequest with the specified URL.
HttpWebRequest^ myHttpWebRequest = (HttpWebRequest^)( WebRequest::Create( url ) );
// Sends the HttpWebRequest and waits for the response.

// Gets the stream associated with the response.
Stream^ receiveStream = myHttpWebResponse->GetResponseStream();
Encoding^ encode = System::Text::Encoding::GetEncoding( "utf-8" );
// Pipes the stream to a higher level stream reader with the required encoding format.
StreamReader^ readStream = gcnew StreamReader( receiveStream,encode );
Console::WriteLine( "\r\nResponse stream received." );

La GetResponseStream méthode retourne le flux de données de la ressource Internet demandée.
Note
Vous devez appeler l’une Stream.Closedes méthodes , Stream.Dispose, HttpWebResponse.Closeou HttpWebResponse.Dispose pour fermer le flux et libérer la connexion en vue d’une réutilisation. Il n’est pas nécessaire de fermer ou de supprimer les deux Stream instances et HttpWebResponse , mais cela ne provoque pas d’erreur. L’échec de la fermeture ou de la suppression du flux entraîne l’absence de connexions de votre application.
