Delegate , Event in 2.0

 

• Define custom eventargs first if necessary
• Define delegate
• public delegate void MathMessage(string msg,int result);
• Define event with new created delegate () (so event is  a special delegate with two special parameters (sender, eventargs)
• public event MathMessage ComputationFinished;
• Define methods (can define anonymous method)
• Register methods with event (event+=method name , new way)
