(How) is it possible to bind/rebind a method to work with a delegate of a different signature?

Question

I\'m a c++ developer having used signals & slots in c++ which to me seems to be analogous to delegates in c#. I\'ve found myself at a loss in searching for the functiona

Answer 1

Try the following

class Example {
  static void foo(int i) {
    Console.WriteLine(i);
  }
  public static void Main() {
    Action someCallback = () => foo(5);
    someCallback();
  }
}

Or for something even closer to the C++ counter part

class Example {
  static void foo(int i) {
    Console.WriteLine(i);
  }
  static Action bind(Action action, T value) {
    return () => action(value);
  }
  public static void Main() {
    Action someCallback = bind(foo, 5);
    someCallback();
  }
}

Explanation. What's happening here is that I am creating a new delegate by means of a lambda expression. The lambda is the expression starting with () =>. In this case it creates a delegate accepting no arguments and producing no value. It is compatible with the type Action.
