One shot events using Lambda in C#

Question

I find myself doing this sort of thing quite often:-

 EventHandler eh = null;  //can\'t assign lambda directly since it uses eh
 eh = (s, args) =>
 {
     //s

Another user encountered a very similar problem, and I believe the solution in that thread applies here.

In particular, what you have is not an instance of the publish/subscribe pattern, its a message queue. Its easy enough to create your own message queue using a Queue{EventHandler}, where you dequeue events as you invoke them.

So instead of hooking on to an event handler, your "one-shot" events should expose a method allowing clients to add an function to the message queue.
