public static System.Xml.Linq.XNamespace Xmlns { get; }

Public Shared ReadOnly Property Xmlns As XNamespace

Property Value

Examples

The following example shows how to add a namespace to an XML tree. The namespace for the attribute that declares the namespace is the namespace returned by this property.

XNamespace aw = "http://www.adventure-works.com";  
XElement root = new XElement(aw + "Root",  
    new XAttribute(XNamespace.Xmlns + "aw", "http://www.adventure-works.com"),  
    new XElement(aw + "Child", "content")  
);  
Console.WriteLine(root);  
Dim root = <aw:Root xmlns:aw="http://www.adventure-works.com">  
               <aw:Child>content</aw:Child>  
           </aw:Root>  
Console.WriteLine(root)  

In Visual Basic, the preferred idiom is:

Imports <xmlns:aw='http://www.adventure-works.com'>  
  
Module Module1  
    Sub Main()  
        Dim root As XElement = _  
            <aw:Root>  
                <aw:Child>content</aw:Child>  
            </aw:Root>  
        Console.WriteLine(root)  
    End Sub  
End Module  

This example produces the following output:

<aw:Root xmlns:aw="http://www.adventure-works.com">  
  <aw:Child>content</aw:Child>  
</aw:Root>  

Remarks

When you declare namespaces, the namespace attributes themselves are in the xmlns namespace. The W3C standard specifies that this namespace does not have to be declared as an attribute in the XML tree. It is a reserved namespace that is always automatically available in the XML parser.
