XNamespace.Addition(XNamespace, String) Operator

Definition

Namespace:

Source:

Combines an XNamespace object with a local name to create an XName.

public:
 static System::Xml::Linq::XName ^ operator +(System::Xml::Linq::XNamespace ^ ns, System::String ^ localName);
public static System.Xml.Linq.XName operator + (System.Xml.Linq.XNamespace ns, string localName);
static member ( + ) : System.Xml.Linq.XNamespace * string -> System.Xml.Linq.XName
Public Shared Operator + (ns As XNamespace, localName As String) As XName

Parameters

ns
XNamespace

An XNamespace that contains the namespace.

localName
String

A String that contains the local name.

Returns

XName

The new XName constructed from the namespace and local name.

Examples

The following example shows the use of the + operator to create an XName from an XNamespace and a local name.

XNamespace aw = "http://www.adventure-works.com";
XElement root = new XElement(aw + "Root",
    new XElement(aw + "Child")
);
Console.WriteLine(root);

Dim aw As XNamespace = "http://www.adventure-works.com"
Dim root As XElement = New XElement(aw + "Root", _
    New XElement(aw + "Child") _
)
Console.WriteLine(root)

In Visual Basic, this is the preferred idiom:

Imports <xmlns="http://www.adventure-works.com">

Module Module1
    Sub Main()
        Dim aw As XNamespace = GetXmlNamespace()
        Dim root As XElement = _
            <Root>
                <Child/>
            </Root>
        Console.WriteLine(root)
    End Sub
End Module

This example produces the following output:

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

Remarks

This operator enables the common idiom of combining a namespace and a local name in the construction of an element or attribute. This idiom provides some of the benefits of having namespace prefixes, in that you can refer to a namespace using a variable that is short. This eliminates syntactic noise in the code that creates XML trees.
