XmlTextReader.LineNumber-Eigenschaft
Ruft die aktuelle Zeilennummer ab.
Namespace: System.Xml
Assembly: System.Xml (in system.xml.dll)
Syntax
'Declaration
Public ReadOnly Property LineNumber As Integer
'Usage
Dim instance As XmlTextReader
Dim value As Integer
value = instance.LineNumber
public int LineNumber { get; }
public:
virtual property int LineNumber {
int get () sealed;
}
/** @property */
public final int get_LineNumber ()
public final function get LineNumber () : int
Eigenschaftenwert
Die aktuelle Zeilennummer.
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.
Diese Eigenschaft wird i. d. R. für Fehlerberichte verwendet, kann aber jederzeit aufgerufen werden. Der Anfangswert für diese Eigenschaft ist 1.
In Kombination mit der LinePosition zeigt der Wert 1,1 den Dokumentanfang an.
Beispiel
Im folgenden Beispiel werden die einzelnen Knoten mit ihrer Tiefe, Zeilennummer und Zeilenposition angezeigt.
