Events and delegate types

[jochemstoel]

Can we use delegates like below, is there an equivalent of this using CLR? If so, how would I go about doing that?

using System;

namespace SampleApp {
   public delegate string MyDel(string str);
	
   class EventProgram {
      event MyDel MyEvent;
		
      public EventProgram() {
         this.MyEvent += new MyDel(this.WelcomeUser);
      }
		
      public string WelcomeUser(string username) {
         return "Welcome " + username;
      }
		
      static void Main(string[] args) {
         EventProgram obj1 = new EventProgram();
         string result = obj1.MyEvent("AtsushiSuzuki");
         Console.WriteLine(result);
      }

   }
}

You can consume .NET events by event.add(callback) and event.remove(callback). You cannnot define .NET events (this is by design), or invoke an event (not implemented).
