title: How should i create a callback
body: <p>What is the best way to write a callback? I only need to call 1 function that has the sig of void (string, int); and this would need to invoke a class since i have member objs that i need to process. Whats the best way to write this? in C i would do pass a func pointer and an void*obj. i dislike that and i suspect there is a better way to do this in C#?</p>
