XmlTextReader.Depth-Eigenschaft
Ruft die Tiefe des aktuellen Knotens im XML-Dokument ab.
Namespace: System.Xml
Assembly: System.Xml (in system.xml.dll)
Syntax
'Declaration
Public Overrides ReadOnly Property Depth As Integer
'Usage
Dim instance As XmlTextReader
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 empfohlene Vorgehensweise für die Version Microsoft .NET Framework, Version 2.0 besteht darin, mithilfe der System.Xml.XmlReader.Create-Methode XmlReader-Instanzen zu erstellen. So können Sie die neuen Features dieser Version in vollem Umfang nutzen. Weitere Informationen finden Sie unter Erstellen von XML-Readern.
Beispiel
Im folgenden Beispiel werden die einzelnen Knoten mit ihrer Tiefe, Zeilennummer und Zeilenposition angezeigt.
