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.
