XmlTextAttribute-Konstruktor ()

Initialisiert eine neue Instanz der XmlTextAttribute-Klasse.

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

Syntax

'Declaration
Public Sub New
'Usage
Dim instance As New XmlTextAttribute

public XmlTextAttribute ()

public:
XmlTextAttribute ()

public XmlTextAttribute ()

public function XmlTextAttribute ()

Hinweise

Sie können die Art, in der XmlSerializer ein öffentliches Feld oder eine öffentliche Lese-/Schreib-Eigenschaft serialisiert, überschreiben, indem Sie XmlAttributes erstellen und die entsprechende XmlText-Eigenschaft auf XmlTextAttribute festlegen. Weitere Informationen finden Sie unter der XmlAttributeOverrides-Klasse.

Beispiel

Im folgenden Beispiel wird eine Klasse serialisiert, die das öffentliche Feld Comment enthält. Im Beispiel wird ein XmlTextAttribute auf das Feld angewendet und dabei die Serialisierung als XML-Element überschrieben, sodass es als XML-Text serialisiert wird.
