XmlTextReader.LinePosition Property

Gets the current line position.

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

public int LinePosition { get; }
/** @property */
public final int get_LinePosition ()

public final function get LinePosition () : int

Property Value

The current line position.

NoteNote

In the Microsoft .NET Framework version 2.0 release, the recommended practice is to create XmlReader instances using the System.Xml.XmlReader.Create method. This allows you to take full advantage of the new features introduced in this release. For more information, see Creating XML Readers.

This property is most commonly used for error reporting, but can be called at any time. The property's starting value is 1.

The position indicated is the first character of text in the markup.

 <root>
 abc<tag/>
 </root>

On the first line of the preceding XML text, a LinePosition of 2 corresponds to the character r; on the second line, a LinePosition of 5 corresponds to the character t; and on the third line, a LinePosition of 3 corresponds to the character r.

Combined with LineNumber, a value of 1,1 indicates the start of the document.

The following example displays each node including its depth, line number, and line position.

using System.IO;
using System.Xml;
