C# - adding some rubyness: times extension method for ints

times.cs

using System;
using System.Linq;

namespace Times {
    static class Extensions {
        public static void times(this int t, Action f) {
            for (int i = 0; i < t; ++i) {
                f();
            }
        }
    }

    class Program {
        static void Greet() {
            Console.WriteLine("Hi!");
        }

        static void Main() {
            5.times(Greet);
        }
    }
}
