Question

I am trying to make a new Timers class to aid with my learning of c#. How would I let an argument for a function be a function?

Answer 1

It’s pretty simple. Just make the argument be some kind of delegate type, like Action or Func.

void PassAnAction(Action action)
{
    action(); // call the action
}

T PassAFunction<T>(Func<T> function)
{
    return function();
}
