There is no restriction on how static and instance events and event handlers are used with one another. You can subscribe a static method as a handler for an instance event or subscribe an instance method as a handler for a static event. However, as with accessing other instance members from a static method defined in the same class hierarchy, you cannot publish an instance event or subscribe any handler for an instance event from within a static method, constructor, or property accessor that is defined in the same class or class hierarchy where the instance event is referenced. You can only make reference to a public instance event from within a static method using an accessible object reference to a class instance that defines the event. For more information on publishing and subscribing handlers for class events, see Publishing and subscribing to class events.
