Ruft den gekennzeichneten Namen des aktuellen Knotens ab.

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

Syntax

'Declaration
Public Overrides ReadOnly Property Name As String
'Usage
Dim instance As XmlValidatingReader
Dim value As String

value = instance.Name

public override string Name { get; }

public:
virtual property String^ Name {
    String^ get () override;
