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

Syntax

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

value = instance.Name

public override string Name { get; }

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

/** @property */
public String get_Name ()

public override function get Name () : String

Eigenschaftenwert

Der gekennzeichnete Name des aktuellen Knotens. Der Name für das <bk:book>-Element lautet z. B. bk:book. Der zurückgegebene Name hängt vom NodeType des Knotens ab. Die folgenden Knotentypen geben die jeweils aufgeführten Werte zurück. Alle anderen Knotentypen geben eine leere Zeichenfolge zurück.

Im Beispiel wird die Datei items.xml als Eingabe verwendet.

<?xml version="1.0"?>
<!-- This is a sample XML document -->
<!DOCTYPE Items [<!ENTITY number "123">]>

  <Item>Test with a char entity: &#65;</Item>
  <!-- Fourteen chars in this element.-->
  <Item>1234567890ABCD</Item>
