Returns identifiers for routed events that have been registered to the event system.
Assembly: PresentationCore (in PresentationCore.dll)
More RoutedEvent objects can be registered later. This method gets a snapshot and the collection of routed events is writeable throughout an application's lifetime. The collection returned might be quite large. Even just counting the events that are part of the WPF APIs, the collection count is in the high hundreds.
