XmlNodeReader.NodeType Property

Gets the type of the current node.

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

public override XmlNodeType NodeType { get; }
/** @property */
public XmlNodeType get_NodeType ()

public override function get NodeType () : XmlNodeType

Property Value

One of the XmlNodeType values representing the type of the current node.

NoteNote

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

The following example reads an XML and displays each of the nodes.

using System;
using System.IO;
using System.Xml;

public class Sample
{
  private const String filename = "items.xml";

  public static void Main()
  {
    XmlNodeReader reader = null;

    try
    {           
        //Create an XmlNodeReader to read the XmlDocument.
        XmlDocument doc = new XmlDocument();
        doc.Load(filename);
        reader = new XmlNodeReader(doc);

        //Parse the file and display each of the nodes.
        while (reader.Read())
        {
           switch (reader.NodeType)
           {
             case XmlNodeType.Element:
               Console.Write("<{0}>", reader.Name);
               break;
             case XmlNodeType.Text:
               Console.Write(reader.Value);
               break;
             case XmlNodeType.CDATA:
               Console.Write(reader.Value);

             case XmlNodeType.XmlDeclaration:
               Console.Write("<?xml version='1.0'?>");
               break;

           }       
          }

     finally
     {
       if (reader!=null)
         reader.Close();
     }
  }

The example uses the file, items.xml, as input.
