Beispiele

Der folgende Code zeigt die Verwendung einer einzelnen Auslöseaktivität in einem Workflow für die Implementierung der Ausnahmebehandlung. In diesem Beispiel wird das Festlegen von FaultType auf null gezeigt. Dieses Codebeispiel stammt aus dem Throw SDK-Beispiel in der Datei ThrowWorkFlow.cs. Weitere Informationen finden Sie unter Verwenden von Throw.
