Eigenschaftswert

Ein DtsError-Objekt.

Beispiele

Das folgende Codebeispiel erstellt eine Aufgabe Send Mail und fügt sie einem Paket hinzu. Nicht alle erforderlichen Eigenschaften der Aufgabe Send Mail sind gesetzt, daher gibt es beim Ausführen des Pakets Fehler und Warnungen in den DtsErrors und DtsWarnings Sammlungen. Die Methode Contains wird verwendet, um zu prüfen, ob die Sammlungen mit der Syntax DtsErrors[index] zugänglich sind, und falls ja, erhält sie einige Eigenschaften mit dieser Syntax.

Hinweise

Wenn der Aufruf der Methode Contains zurückkehrt true, können Sie über die Syntax Connections[index]auf das angegebene Element in der Sammlung zugreifen. Wenn die Methode Contains zurückgibt false, wirft diese Eigenschaft eine Ausnahme. In C# ist diese Eigenschaft der Indexer für die DtsErrors Klasse.
