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

Examples

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

#using <System.Xml.dll>

using namespace System;
using namespace System::IO;
using namespace System::Xml;
int main()
{
   XmlTextReader^ reader = nullptr;
   try
   {
      
      // Load the reader with the XML file.
      reader = gcnew 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 {0}", reader->NamespaceURI );
            }
         }
      }
   }
   finally
   {
      if ( reader != nullptr )
            reader->Close();
   }

}
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)
          reader.Close();
      }

    Public Shared Sub Main()
        Dim reader As XmlTextReader = Nothing
        
        Try
            ' Load the reader with the XML file.

            While reader.Read()

                        Console.WriteLine("<{0}>", reader.LocalName)

                        Console.Write("<{0}:{1}>", reader.Prefix, reader.LocalName)
                        Console.WriteLine(" The namespace URI is " & reader.NamespaceURI)
                    End If
                End If
            End While
        
        Finally
            If Not (reader Is Nothing) Then
                reader.Close()
            End If
        End Try
    End Sub
End Class

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


<book xmlns:bk='urn:samples'>
  <title>Pride And Prejudice</title>
  <bk:genre>novel</bk:genre>
</book>

Remarks

Note

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 relevant to Element and Attribute nodes only.
