C# delegates are similar to pointers to functions, in C or C++. A delegate is a reference type variable that holds the reference to a method. The reference can be changed at runtime.

Delegates are especially used for implementing events and the call-back methods. All delegates are implicitly derived from the System.Delegate class.

```
using System;delegate int ReplaceNumber(int n);namespace DelegateApp{   class UseDelegate   {      static int number = 10;      public static int AddNumber(int p)      {         number += p;         return number;      }      public static int MultNumber(int q)      {         number *= q;         return number;      }      public static int getNumber()      {         return number;      }      static void Main(string[] args)      {         //create delegate instances         ReplaceNumber numberc1 = new ReplaceNumber(AddNumber);         ReplaceNumber numberc2 = new ReplaceNumber(MultNumber);                  //calling the methods using the delegate objects         numberc1(25);         Console.WriteLine("First Value of Number: {0}", getNumber());         numberc2(5);         Console.WriteLine("Second Value of Number: {0}", getNumber());         Console.ReadKey();      }   }}
```
