Parameters
- eventHandler
- Type: SystemDelegate
- sender
- Type: SystemObject
- args (Optional)
- Type: TEventArgs
- exceptionCallback (Optional)
- Type: SystemActionException
Called whenever an exception is raised. If this is supplied then throwEventHelperException has no effect,
all handlers will be called and this function won't let exceptions thrown by the handlers bubble (unless the callback
throws an exception, in which case an EventHelperException that wraps the exception(s) will be thrown). - throwEventHelperException (Optional)
- Type: SystemBoolean
True if exceptions thrown by event handlers should be wrapped into a single EventHelperException, false if the first
exception thrown by an event handler should be rethrown. If this is false then the first event handler that throws
an exception will stop all other event handlers from being called.
Type Parameters
- TEventArgs
Remarks
Note that this is roughly 6x - 9x slower than a normal event handler call.
