The XNamespace that corresponds to no namespace.

Examples

The following example shows uses this property to determine which elements are in no namespace.

XNamespace aw = "http://www.adventure-works.com";

XElement root = new XElement("Root",
    new XElement(aw + "ChildInNamespace", "content"),
    new XElement("ChildInNoNamespace", "content")
);

if (root.Name.Namespace == XNamespace.None)
    Console.WriteLine("Root element is in no namespace");
else
    Console.WriteLine("Root element is in a namespace");

if (root.Element(aw + "ChildInNamespace").Name.Namespace == XNamespace.None)
    Console.WriteLine("ChildInNamespace element is in no namespace");
else
    Console.WriteLine("ChildInNamespace element is in a namespace");

if (root.Element("ChildInNoNamespace").Name.Namespace == XNamespace.None)
    Console.WriteLine("ChildInNoNamespace element is in no namespace");
else
    Console.WriteLine("ChildInNoNamespace element is in a namespace");
Imports <xmlns:aw="http://www.adventure-works.com">

Module Module1
    Sub Main()
        Dim root As XElement = _
            <Root>
                <aw:ChildInNamespace>content</aw:ChildInNamespace>
                <ChildInNoNamespace>content</ChildInNoNamespace>
            </Root>

        If (root.Name.Namespace Is XNamespace.None) Then
            Console.WriteLine("Root element is in no namespace")
        Else
            Console.WriteLine("Root element is in a namespace")
        End If

        If (root.Element(GetXmlNamespace(aw) + "ChildInNamespace") _
                .Name.Namespace Is XNamespace.None) Then
            Console.WriteLine("ChildInNamespace element is in no namespace")
        Else
            Console.WriteLine("ChildInNamespace element is in a namespace")
        End If

        If (root.Element("ChildInNoNamespace") _
                .Name.Namespace Is XNamespace.None) Then
            Console.WriteLine("ChildInNoNamespace element is in no namespace")
        Else
            Console.WriteLine("ChildInNoNamespace element is in a namespace")
        End If
    End Sub
End Module

This example produces the following output:

Root element is in no namespace
ChildInNamespace element is in a namespace
ChildInNoNamespace element is in no namespace

Remarks

If an element or attribute is in no namespace, its namespace will be set to the namespace returned by this property.
