C# Delegates

 A Simple Example of Delegates

using System;
public class Test
 {
  public delegate int CalculationHandler(int x, int y);
  static void Main(string[]  args)
   {
     Math math = new Math();
    //create a new instance of the delegate class

     CalculationHandler sumHandler = new CalculationHandler(math.Sum);
    //invoke the delegate
      int result = sumHandler(8,9);
     Console.WriteLine("Result is: " + result);
     }
   }

 public class Math
  {
    public int Sum(int x, int y)
     {
       return x + y;
     }
  }
