Eigenschaftswert

XmlTypeAttribute

Ein XmlTypeAttribute, das ein XmlTypeAttribute überschreibt, das einer Klassendeklaration zugewiesen wurde.

Beispiele

Im folgenden Beispiel wird ein XmlTypeAttribute Objekt erstellt und der XmlType Eigenschaft eines XmlAttributes Objekts zugewiesen.

Hinweise

Dies XmlTypeAttribute kann verwendet werden, um zu steuern, wie ein Typ von der XmlSerializer. Wenn beispielsweise ein Typ serialisiert wird, wird der XmlSerializer Klassenname standardmäßig als XML-Elementname verwendet. Durch Erstellen einer XmlTypeAttribute, durch Festlegen der XmlType Eigenschaft und Erstellen eines XmlAttributeOverrides Objekts können Sie den XML-Elementnamen ändern.
