i get knocked for being wrong for not using ready made class and functions

using System;

namespace ConsoleApplication1
{
    public class Program
    {
        public delegate int OuterDelegate(object[] o);
        public delegate int InnerDelegate(object[] o);

                t += (int)io;
            }
            return t;
        }


        static void Main(string[] args)
        {
            Program p = new Program();

            InnerDelegate oInnerDelegate = new InnerDelegate(p.MyMethod);
            OuterDelegate oOuterDelegate = new OuterDelegate(oInnerDelegate);

            int i = oOuterDelegate(new object[] { 1, 2, 3, 4 });
            Console.WriteLine(i.ToString());

            Console.WriteLine("done");
            Console.Read();
        }        
    }
}

Now, the question I still have is how could I change the OuterDelegate to execute some code on what was returned from the InnerDelegate?

delegate int D1(params int[] list);
delegate void D2(int p);

class DeliDelegate {
  internal void Run(){
    InvokeBoth(ShowInt, Sum, 1, 2, 3, 4, 5);
    InvokeBothAndSome(ShowInt, Sum, 1, 2, 3, 4, 5);
  }

  void InvokeBoth(D2 outer, D1 inner, params int[] p) {
    outer(inner(p));
  }

  void InvokeBothAndSome(D2 outer, D1 inner, params int[] p) {
    int res = inner(p);
    res = res * 6;
    outer(res);
  }

  int Sum(params int[] i) {
    int result = 0;
    foreach (int j in i) {
      result += j;
    }
    return result;
  }

  void ShowInt(int i) {
    Console.WriteLine("Value is {0}", i);
  }
}
