Hi George,

I took a look an the IL of the following code:

delegate void MyEventHandler(object sender, EventArgs e);

The compiler generates a class derived from MulticastDelagate
consisting of these "runtime managed" (thus empty) methods:

.ctor
Invoke
BeginInvoke
EndInvoke

However, you *can* provide an CIL implementation too.
I changed "runtime managed" to "cil managed" and
it works:

  .method public hidebysig virtual instance void
          Invoke(object sender,
                 class [mscorlib]System.EventArgs e) cil managed
  {
    ldstr      "test"
    call       void [mscorlib]System.Console::WriteLine(string)
    ret
  }

So if you don't like the "runtime managed" black boxes
you still can roll your own delegate implementation, though
probably a bad idea.

bye
Rob

Hi Robert,

it's "cannot" :))

exactly. this is the point of my question :) I want to know what is inside
these blackboxes (runtime managed). For example, I think that the .cctor sets
the two private fields "_target" and "_methodPtr". What else it does?

How it's the invocation with Invoke optimized?  

All the best, George
