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

Syntax

'Declaration
Public Overrides ReadOnly Property Depth As Integer
'Usage
Dim instance As XmlValidatingReader
Dim value As Integer

value = instance.Depth

public override int Depth { get; }

public:
virtual property int Depth {
    int get () override;

/** @property */
public int get_Depth ()

public override function get Depth () : int

Eigenschaftenwert

Die Tiefe des aktuellen Knotens im XML-Dokument.

Hinweise

Hinweis

Die XmlValidatingReader-Klasse ist in Microsoft .NET Framework, Version 2.0 veraltet. Sie können eine Instanz eines validierenden XmlReader mithilfe der XmlReaderSettings-Klasse und der Create-Methode erstellen. Weitere Informationen finden Sie unter Validieren von XML-Daten mit "XmlReader".

Im folgenden Beispiel werden die einzelnen Knoten mit ihrer Tiefe, Zeilennummer und Zeilenposition angezeigt.
