9@104 states "Use the sender/arguments signature for event handlers".
This is very good, but if you use that, there are some additional rules you should obey:
- Do not pass
null as the event sender parameter when raising a non-static event.
(Static events do NOT have an (object) instance and thus NO sender.
- Do not pass
null as the event data parameter when raising an event.
Use EventArgs.Empty when no relevant data can/should be sent with the event.
These two come from MSDN (see http://msdn.microsoft.com/en-us/library/ms229011.aspx). |
