Hinweise

Die ICredentials -Schnittstelle stellt die GetCredential -Methode für Objekte bereit, die Netzwerkanmeldeinformationen für Anwendungen bereitstellen.

Methoden

GetCredential(Uri, String)

Gibt ein NetworkCredential-Objekt zurück, das dem angegebenen URI und Authentifizierungstyp zugeordnet ist.
