Wenn Sie mit dem Typ haben, sollten Sie es entweder direkt oder indirekt freigeben.When you have finished using the type, you should dispose of it either directly or indirectly. Damit des Typs direkt freigegeben werden, rufen Sie die Dispose -Methode in einer try / catch Block.To dispose of the type directly, call its Dispose method in a try/catch block. Um sie indirekt 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 "mithilfe von ein-Objekt, das implementiert" IDisposable "" in der IDisposable schnittstellenthema.For more information, see the "Using an Object that Implements IDisposable" section in the IDisposable interface topic.

Für apps, die als Ziel der .NET Framework 4.5.2.NET Framework 4.5.2 und früheren Versionen der X509Certificate2 -Klasse implementiert nicht die IDisposable Schnittstelle, und daher keinen keine Dispose Methode.For apps that target the .NET Framework 4.5.2.NET Framework 4.5.2 and earlier versions, the X509Certificate2 class does not implement the IDisposable interface and therefore does not have a Dispose method.
