Beispiele

Im folgenden Codebeispiel wird ein FileSystemTask und BulkInsertTask einem Paket hinzugefügt, und die Aufgaben in einer-Schleife werden mithilfe der- InnerObject Methode von abgerufen TaskHost , um den Tasktyp zu bestimmen.

Hinweise

Sie können die jeweilige Aufgaben Instanz abrufen, indem Sie die InnerObject der TaskHost als Aufgabentyp umwandeln. Anschließend verwenden Sie das-Objekt der Aufgabe, um direkt auf seine Methoden und Eigenschaften zuzugreifen.
