Beispiele

Im folgenden Beispiel wird eine Klasse mit dem Namen Transportation eines Felds MyVehicles serialisiert, das ein Array von Vehicle Objekten zurückgibt. Das Beispiel wendet das XmlArrayItemAttribute Feld an, sodass instanzen XmlSerializer der Car Klasse eingefügt werden können, die von der Vehicle Klasse abgeleitet werden, in das Array.
