Poznámky
Lze XmlTypeAttribute použít k řízení způsobu serializace XmlSerializertypu pomocí . Pokud je například typ serializován, XmlSerializer použije například název třídy jako název elementu XML. Vytvořením XmlTypeAttribute, nastavením XmlType vlastnosti na ni a vytvořením objektu XmlAttributeOverrides můžete změnit název elementu XML.
