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

public override string NamespaceURI { get; }

Property Value

Type: System.String
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The XmlValidatingReader class is obsolete in .NET Framework 2.0. You can create a validating XmlReader instance by using the XmlReaderSettings class and the Create method. For more information, see the Remarks section of the XmlReader reference page.

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
