Delegates and Lambda Expressions

Question

Hello Friends,

I was wondering do I need to refactor this codes that is using a delegate with a lambda expression, or is this best practice? Thanks !

 

namespace Delagate
{
    delegate bool MeDelagate(int n);

    class Program
    {
        //static bool LessThanFive(int n) { return n < 5; }
       // static bool LessThanTen(int n) { return n < 10; }
        //static bool GreaterThanThirteen(int n) { return n > 13; }

        static void Main(string[] args)
        {
            int[] numbers = new[] { 2, 7, 3, 7, 9, 17,5, 1, 8, 1700 };
            IEnumerable<int> result = RunNumbersThroughGauntlet(numbers, n => n > 1500);
            foreach (int n in result)
                Console.WriteLine(n);
        }
        static IEnumerable<int> RunNumbersThroughGauntlet(IEnumerable<int> numbers, MeDelagate gauntlet)
        {
            foreach (int number in numbers)
                if (gauntlet(number))
                    yield return number;
        }
    }
}
