Return Value

The last element, or a null reference (Nothing in Microsoft Visual Basic .NET) if there is no such element.

An AutomationElement can have additional child elements that do not match the current view condition and thus are not returned when navigating the element tree.

The structure of the AutomationElement tree changes as the visible user interface (UI) elements on the desktop change. It is not guaranteed that an element returned as the last child element will be returned as the last child on subsequent passes.
