public:
 static property System::Xml::Linq::XNamespace ^ None { System::Xml::Linq::XNamespace ^ get(); };
public static System.Xml.Linq.XNamespace None { get; }
member this.None : System.Xml.Linq.XNamespace
Public Shared ReadOnly Property None As XNamespace

Eigenschaftswert

XNamespace

Der XNamespace, der keinem Namespace entspricht.The XNamespace that corresponds to no namespace.

Beispiele

Im folgenden Beispiel wird diese Eigenschaft verwendet, um zu bestimmen, welche Elemente keinen Namespace haben.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

Dieses Beispiel erzeugt die folgende Ausgabe:This example produces the following output:

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

Hinweise

Wenn ein Element oder Attribut keinen Namespace hat, wird sein Namespace auf den von dieser Eigenschaft zurückgegebenen Namespace festgelegt.If an element or attribute is in no namespace, its namespace will be set to the namespace returned by this property.
