Beispiele

Das folgende Beispiel zeigt die Verwendung von Membern WindowsIdentity der-Klasse.The following example shows the use of members of WindowsIdentity class. Ein Beispiel für das Abrufen eines Windows-Konto Tokens durch einen-Befehl der nicht verwalteten Win32 LogonUser -Funktion und die Verwendung dieses Tokens, um die Identität eines anderen Benutzers anzunehmen, finden Sie unter der WindowsImpersonationContext -Klasse.For an example showing how to obtain a Windows account token through a call to the unmanaged Win32 LogonUser function, and use that token to impersonate another user, see the WindowsImpersonationContext class.

Hinweise

Rufen Sie GetCurrent die Methode auf, WindowsIdentity um ein-Objekt zu erstellen, das den aktuellen Benutzer darstellt.Call the GetCurrent method to create a WindowsIdentity object that represents the current user.

Wichtig

Dieser Typ implementiert die IDisposable-Schnittstelle.This type implements the IDisposable interface. Nach Abschluss der Verwendung sollten Sie den Typ entweder direkt oder indirekt löschen.When you have finished using the type, you should dispose of it either directly or indirectly. Zum direkten Löschen des Typs rufen Sie seine Dispose-Methode in einem try/catch-Block auf.To dispose of the type directly, call its Dispose method in a try/catch block. Zum indirekten Löschen verwenden Sie ein Sprachkonstrukt wie using (in C#) oder Using (in Visual Basic).To dispose of it indirectly, use a language construct such as using (in C#) or Using (in Visual Basic). Weitere Informationen finden Sie im Abschnitt „Verwenden eines Objekts, das IDisposable implementiert“ des Themas „Die IDisposable-Schnittstelle“.For more information, see the "Using an Object that Implements IDisposable" section in the IDisposable interface topic.
