#using <System.Xml.dll>

using namespace System;
using namespace System::IO;

   XmlElement^ elem = dynamic_cast<XmlElement^>(doc->DocumentElement->FirstChild);
   Console::Write( "{0}:{1} = {2}", elem->Prefix, elem->LocalName, elem->InnerText );
   Console::WriteLine( "\t namespaceURI={0}", elem->NamespaceURI );
}

// This code produces the following output.
// bk:ISBN = 1-861001-57-5  namespaceURI=urn:samples

    Console.WriteLine("\t namespaceURI=" + elem.NamespaceURI);
  }
}

// This code produces the following output.
// bk:ISBN = 1-861001-57-5  namespaceURI=urn:samples

Imports System.IO
Imports System.Xml

public class Sample

  public shared sub Main()

    Dim doc as XmlDocument = new XmlDocument()
    doc.LoadXml("<book xmlns:bk='urn:samples'>" & _
                "<bk:ISBN>1-861001-57-5</bk:ISBN>" & _
                "<title>Pride And Prejudice</title>" & _
                "</book>")

    ' Display information on the ISBN element.
    Dim elem as XmlElement 
    elem = CType(doc.DocumentElement.ChildNodes.Item(0),XmlElement) 
    Console.Write("{0}:{1} = {2}", elem.Prefix, elem.LocalName, elem.InnerText)
    Console.WriteLine("  namespaceURI=" + elem.NamespaceURI)
  end sub
end class

' This code produces the following output.
' bk:ISBN = 1-861001-57-5  namespaceURI=urn:samples

備註

這是在建立時指定的命名空間 URI。 例如， NamespaceURI 是元素 bk：book xmlns：bk= 「urn：samples」 的 < urn：samples>
