// element is an AutomationElement.
object objPattern;
SelectionPattern selPattern;
if (true == element.TryGetCurrentPattern(SelectionPattern.Pattern, out objPattern))
{
selPattern = objPattern as SelectionPattern;
}
' element is an AutomationElement.

If True = element.TryGetCurrentPattern(SelectionPattern.Pattern, objPattern) Then
selPattern = DirectCast(objPattern, SelectionPattern)
End If
