XPathNavigator.LocalName Eigenschaft

public:
 abstract property System::String ^ LocalName { System::String ^ get(); };

public abstract string LocalName { get; }

member this.LocalName : string

Public MustOverride ReadOnly Property LocalName As String

Eigenschaftswert

Ein String, der den lokalen Namen des aktuellen Knotens enthält, oder Empty, wenn der aktuelle Knoten keinen Namen aufweist (z. B. bei Text- oder Kommentarknoten).

Beispiele

Das folgende Beispiel durchläuft die Knotenstruktur rekursiv und zeigt Informationen zu Element knoten und Text an.

Hinweise

Der zurückgegebene lokale Name hängt vom des XPathNodeType aktuellen Knotens ab. Der lokale Name für das <bk:book> -Element lautet z. B book. .

In der folgenden Tabelle wird der von der LocalName -Eigenschaft zurückgegebene Wert basierend auf dem XPathNodeType des aktuellen Knotens aufgeführt.
