Gets the namespace associated with a particular prefix for this XElement.

public:
 System::Xml::Linq::XNamespace ^ GetNamespaceOfPrefix(System::String ^ prefix);
public System.Xml.Linq.XNamespace GetNamespaceOfPrefix (string prefix);
public System.Xml.Linq.XNamespace? GetNamespaceOfPrefix (string prefix);
member this.GetNamespaceOfPrefix : string -> System.Xml.Linq.XNamespace
Public Function GetNamespaceOfPrefix (prefix As String) As XNamespace

Parameters

prefix
String

A string that contains the namespace prefix to look up.

Returns

XNamespace

An XNamespace for the namespace associated with the prefix for this XElement.

Examples

The following example creates an XML tree that has a namespace with an associated prefix. It then uses this method to retrieve the XNamespace for the prefix.

XElement xmlTree = XElement.Parse("<Root xmlns:aw='http://www.adventure-works.com'/>");
XNamespace awNamespace = xmlTree.GetNamespaceOfPrefix("aw");
Console.WriteLine("Namespace: {0}", awNamespace);

When using Visual Basic, you would typically use the GetXmlNamespace Operator operator, as follows

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

Module Module1
    Sub Main()
        Dim xmlTree As XElement = <aw:Root/>
        Dim awNamespace As XNamespace = GetXmlNamespace(aw)
        Console.WriteLine("Namespace: {0}", awNamespace)
    End Sub
End Module

This example produces the following output:

Namespace: http://www.adventure-works.com

Remarks

This method looks through the XML tree for namespace attributes that are in scope for this element. Namespace prefixes are specified in namespace attributes that are in the XML tree.
