// Send the 'fileWebRequest' and wait for response.
FileWebResponse^ myFileWebResponse = dynamic_cast<FileWebResponse^>(myFileWebRequest->GetResponse());
// Process the response here.
Console::WriteLine( "\nResponse Received::Trying to Close the response stream.." );
// Release resources of response Object*.

Hinweise
Die Close -Methode bereinigt die von einem FileWebResponse verwendeten Ressourcen und schließt den Antwortdatenstrom durch Aufrufen der Stream.Close -Methode.
Hinweis
Der Antwortdatenstrom muss geschlossen werden, um zu vermeiden, dass die Systemressourcen knapp werden. Sie können den Antwortdatenstrom schließen, indem Sie entweder Stream.Close oder aufrufen. Close
