Public Property XmlType As XmlTypeAttribute

Wartość właściwości

XmlTypeAttribute

Element XmlTypeAttribute , który zastępuje XmlTypeAttribute deklarację klasy zastosowaną do klasy.

Uwagi

Może XmlTypeAttribute służyć do kontrolowania, w jaki sposób typ jest serializowany przez XmlSerializer. Na przykład domyślnie, gdy typ jest serializowany, XmlSerializer używa nazwy klasy jako nazwy elementu XML. XmlTypeAttributeTworząc właściwość , ustawiając XmlType jej właściwość i tworząc XmlAttributeOverrides obiekt, można zmienić nazwę elementu XML.
