Multicast delegate weird behavior in C#?

Question

I have this simple event :

public class ClassA
{
    public event Func Ev;
    public int Do(string l)
    {
        return Ev(l);
    }
}
         


        

Answer 1

Invoking a multicast non-void delegate returns the value of the last handler that was executed.

You have very little control over who is first or last. It is a lousy system to use.

That is why most events and delegates return void.
