| Porting to C#, I can create C# events corresponding to Delphi events. But
| those C# events will of course be unicast only.

Not necessarily :-) .C# delegates are always multicast, but you can assign 
only one handler if you wish.

  public delegate void TestHandler(int value);

  {
    private void HandleTest(int value)
    {
      // handler code
    }

    private TestHandler test;

    private void CallTest()
    {
      test = HandleTest; singlecast
      test(123);
      test += HandleTest; // now multicast
    }
  }

You can see that both assigning (singlecast) and += (multicast) are both 
available.
