C# - passing a function of unknown type to another function and calling it

In my program i'm suppose to get a function as a parameter, and call it from within another function. can it be done?

Sure, you could just take in a Delegate and utilize Delegate.DynamicInvoke or Delegate.Method.Invoke. Barring more information, this answers your question.

Thus:

class Foo {
    public void M(Delegate d) {
        d.DynamicInvoke();
    }
}

Action action = () => Console.WriteLine("Hello, world!");
var foo = new Foo();
foo.M(action);
