Parameters

prefix: String

The prefix of the namespace you want to find.

Boolean

true if there is a namespace defined; otherwise, false.

Examples

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

if ( nsmgr->HasNamespace( String::Empty ) )
{
   Console::WriteLine( nsmgr->DefaultNamespace );
}

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

If nsmgr.HasNamespace(String.Empty) Then
    Console.WriteLine(nsmgr.DefaultNamespace)
End If

To determine whether there is a default empty namespace defined, set prefix to String.Empty. A return value of true indicates that there is a default namespace defined in the current scope; false indicates that no default namespace is defined.
