I was just looking at your original code - you're hooking up the event after you call the method which raises the event (which means the event is null - per my suggestion to write code which checks to see if it's null before raising the event).

If you change the order of the code it should work:

            BankAccounts oBank = new BankAccounts();
            oBank.ReaderRetreived += new ReaderRetreivedEvent(ReaderRetreived);  // COMPILE ERROR HERE
            oReader = oBank.GetReader("select * from registers");
