public override string NamespaceURI { get; }

The namespace URI of the current node; otherwise an empty string.

This property is relevant to Element and Attribute nodes only.

NoteNote

The XmlValidatingReader class is obsolete in Microsoft .NET Framework version 2.0. You can create a validating XmlReader instance by using the XmlReaderSettings class and the Create method. For more information, see Validating XML Data with XmlReader.

The following example reads an XML fragment.

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

public class Sample
{
    public static void Main()
    {
        XmlTextReader reader = null;

        try
        {
            //Create the XML fragment to be parsed.
            string xmlFrag = "<book> " +
                            "<title>Pride And Prejudice</title>" +
                            "<bk:genre>novel</bk:genre>" +
                            "</book>";

            //Create the XmlNamespaceManager that is used to
            //look up namespace information.
            NameTable nt = new NameTable();
            XmlNamespaceManager nsmgr = new XmlNamespaceManager(nt);
            nsmgr.AddNamespace("bk", "urn:sample");

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

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

            //Parse the XML fragment.  If they exist, display the   
            //prefix and namespace URI of each element.
            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)
                reader.Close();
        }
    }
} // End class
