call back design pattern executable code is passed as an argument to other code and it is expected to call back at some time.

using System;
using System.Collections.Generic;
using System.Data.Entity;
using System.Linq;
namespace program
{
    class Example
    {
        static void Main(string[] args)
        {
            CallBackdemo callBackdemo = new CallBackdemo();
            callBackdemo.Test();
            Console.ReadLine();
        }
    }
    public class CallBackdemo
    {
        public void Test()
        {
            TaskCompletedCallBack callback = TestCallBack;
            CallBack testCallBack = new CallBack();
            testCallBack.NewTask(callback);
        }
        public void TestCallBack(string result)
        {
            Console.WriteLine(result);
        }
    }
    public delegate void TaskCompletedCallBack(string Result);
    public class CallBack
    {
        public void NewTask(TaskCompletedCallBack taskCompletedCallBack)
        {
            Console.WriteLine("I have started new execution Task.");
            if (taskCompletedCallBack != null)
                taskCompletedCallBack("I have completed execution Task.");
        }
    }
}
