XmlNamespaceManager.HasNamespace Method

Gets a value indicating whether the supplied prefix has a namespace defined for the current pushed scope.

Namespace:  System.Xml
Assembly:  System.Xml (in System.Xml.dll)

public virtual bool HasNamespace(
	string prefix
)

Parameters

prefix
Type: System.String
The prefix of the namespace you want to find.

Return Value

Type: System.Boolean
true if there is a namespace defined; otherwise, false.

To determine whether there is a default empty namespace defined, set prefix to String.Empty. If the method returns true, this indicates that there is a default namespace defined in the current scope. Returning false indicates that no default namespace is defined.

NoteNote

xmlns:x= "" is illegal according to W3C Namespaces in XML recommendation.

The following example displays the default namespace, if one exists.


if (nsmgr.HasNamespace(String.Empty))
  Console.WriteLine(nsmgr.DefaultNamespace);
