What is a custom event accessor used for?

To limit access to the event
To enable direct assignment of events
To simplify event handling
To automatically trigger events

The correct answer is: To limit access to the event

A custom event accessor serves to control how events are accessed and manipulated within a class or structure. By using custom accessors, you can encapsulate the event, allowing you to limit who can subscribe to or unsubscribe from the event. This kind of access control helps maintain the integrity of the event's invocation and the object that raises the event. In many scenarios, custom accessors provide a way to implement additional logic when an event is added or removed. For instance, you might enforce certain conditions under which a subscriber can register for the event, thereby ensuring that the event is only accessed in a manner that’s safe and appropriate according to your application’s architecture and logic. This capability is distinct from other options that revolve around different functionalities such as direct assignment, simplification of event handling, or automatic triggering, which do not specifically address access control mechanisms.
