XmlAttributes.XmlType-Eigenschaft

Ruft ein Objekt ab, das angibt, wie XmlSerializer eine Klasse serialisiert, der das XmlTypeAttribute zugewiesen wurde, oder legt dieses fest.

Namespace: System.Xml.Serialization
Assembly: System.Xml (in system.xml.dll)

Syntax

'Declaration
Public Property XmlType As XmlTypeAttribute
'Usage
Dim instance As XmlAttributes
Dim value As XmlTypeAttribute

value = instance.XmlType

instance.XmlType = value

public XmlTypeAttribute XmlType { get; set; }

public:
property XmlTypeAttribute^ XmlType {
    XmlTypeAttribute^ get ();
    void set (XmlTypeAttribute^ value);
}

/** @property */
public XmlTypeAttribute get_XmlType ()

/** @property */
public void set_XmlType (XmlTypeAttribute value)

public function get XmlType () : XmlTypeAttribute

public function set XmlType (value : XmlTypeAttribute)

Eigenschaftenwert

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

Hinweise

Mit dem XmlTypeAttribute können Sie steuern, wie ein Typ vom XmlSerializer serialisiert wird. Standardmäßig verwendet der XmlSerializer beim Serialisieren eines Typs z. B. den Klassennamen als Namen des XML-Elements. Durch das Erstellen eines XmlTypeAttribute, das Festlegen einer XmlType-Eigenschaft für dieses und das Erstellen eines XmlAttributeOverrides-Objekts können Sie den Namen des XML-Elements ändern.

Beispiel

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