Property Value

Type: System.Xml.Linq.XNamespace
The XNamespace that corresponds to no namespace.

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

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");

This example produces the following output:

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