Maybe this will help:
public delegate void Handler<in T>(T val);
private List<Delegate> m_list = new List<Delegate>();
public void AddListener<T>(Handler<T> handler) {
m_list.Add(handler);
}
public void Call(object eventArg) {
foreach (var handler in m_list) {
handler.DynamicInvoke(eventArg);
}
}
Then, if you have a handler like this:
private void MyHandler(int val) {
// Do something
}
You can add it to the list like this:
AddListener<int>(MyHandler);
(This assumes I correctly understood what you're trying to do. I'm not sure though.)
