The UI for the AutomationElement no longer exists.

The identifier is only guaranteed to be unique to the UI of the desktop on which it was generated. Identifiers can be reused over time.

The format of run-time identifiers might change in future releases. The returned identifier should be treated as an opaque value and used only for comparison; for example, to determine whether an AutomationElement is in the cache.

The following example shows how to retrieve the run-time identifier of an AutomationElement.

// element is an AutomationElement.
int[] id = element.GetRuntimeId();
