XmlValidatingReader.Name Eigenschaft

Definition

Namespace:

System.Xml

Assembly:

System.Xml.ReaderWriter.dll

Quelle:

XmlValidatingReader.cs

Ruft den gekennzeichneten Namen des aktuellen Knotens ab.

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

public override string Name { get; }

member this.Name : string

Public Overrides ReadOnly Property Name As String

Eigenschaftswert

String

Der gekennzeichnete Name des aktuellen Knotens. Beispielsweise Name ist bk:book für das -Element <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.

Knotentyp	Name
Attribute	Der Name des Attributs.
DocumentType	Der Name des Dokumenttyps.
Element	Der Tagname.
EntityReference	Der Name der Entität, auf die verwiesen wird.
ProcessingInstruction	Das Ziel der Verarbeitungsanweisung.
XmlDeclaration	Das xml-Zeichenfolgenliteral.

Beispiele

Im folgenden Beispiel wird eine XML-Datei gelesen und jeder knoten angezeigt.

Hinweis

Die XmlValidatingReader -Klasse ist in .NET Framework 2.0 veraltet. Sie können eine Validierungsinstanz erstellen, XmlReader indem Sie die XmlReaderSettings -Klasse und die Create -Methode verwenden. Weitere Informationen finden Sie im Abschnitt Hinweise unter der XmlReader Referenzseite.
