Prefix Property

XmlTextReader.Prefix Property

Gets the namespace prefix associated with the current node.

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

public override string Prefix { get; }

Property Value

Type: System.String
The namespace prefix associated with the current node.


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.

The following example displays the local name of each node, and, if they exist, the prefix and namespace URI.

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

public class Sample {

  public static void Main() {

    XmlTextReader reader = null;

    try {

       // Load the reader with the XML file.
       reader = new XmlTextReader("book2.xml");

       // Parse the file.  If they exist, display the prefix and  
       // namespace URI of each node. 
       while (reader.Read()) {
         if (reader.IsStartElement()) {
           if (reader.Prefix==String.Empty)
              Console.WriteLine("<{0}>", reader.LocalName);
           else {
               Console.Write("<{0}:{1}>", reader.Prefix, reader.LocalName);
               Console.WriteLine(" The namespace URI is " + reader.NamespaceURI);

     finally {
        if (reader != null)
} // End class

The example uses the file, book2.xml, as input.
