Hinweise

Wichtig

Dieser Typ implementiert die IDisposable-Schnittstelle. Nach Abschluss der Verwendung sollten Sie den Typ entweder direkt oder indirekt löschen. Zum direkten Löschen des Typs rufen Sie seine Dispose-Methode in einem try/catch-Block auf. Zum indirekten Löschen verwenden Sie ein Sprachkonstrukt wie using (in C#) oder Using (in Visual Basic). Weitere Informationen finden Sie im Abschnitt „Verwenden eines Objekts, das IDisposable implementiert“ des Themas „Die IDisposable-Schnittstelle“.

Diese Methode entfernt mehrere Zertifikate aus einem X.509-Zertifikatspeicher. Wenn bei der Entfernung eines Zertifikats ein Fehler auftritt, wird der Vorgang wiederhergestellt, und es werden keine Zertifikate entfernt.
