LineNumber Property

XmlTextReader.LineNumber Property


Gets the current line number.

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

public int LineNumber { get; }

Property Value

Type: System.Int32

The current line number.


Starting with the .NET Framework 2.0, we recommend that you create XmlReader instances by using the XmlReader.Create method to take advantage of new functionality.

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

Combined with LinePosition, 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;
using System.IO;
using System.Xml;

public class Sample{

  public static void Main(){

    // Create the XML fragment to be parsed.
    string xmlFrag  = 

    // Create the XmlNamespaceManager.
    NameTable nt = new NameTable();
    XmlNamespaceManager nsmgr = new XmlNamespaceManager(nt);

    // Create the XmlParserContext.
    XmlParserContext context = new XmlParserContext(null, nsmgr, null, XmlSpace.None);

    // Create the reader.
    XmlTextReader reader = new XmlTextReader(xmlFrag, XmlNodeType.Element, context);

    // Parse the XML and display each node.
    while (reader.Read()){
       switch (reader.NodeType){
         case XmlNodeType.Element:
           Console.Write("{0} {1},{2}  ", reader.Depth, reader.LineNumber, reader.LinePosition);
           Console.WriteLine("<{0}>", reader.Name);
         case XmlNodeType.Text:
           Console.Write("{0} {1},{2}  ", reader.Depth, reader.LineNumber, reader.LinePosition);
           Console.WriteLine("  {0}", reader.Value);
         case XmlNodeType.EndElement:
           Console.Write("{0} {1},{2}  ", reader.Depth, reader.LineNumber, reader.LinePosition);
           Console.WriteLine("</{0}>", reader.Name);

    // Close the reader.
