using System;

delegate void FunctionToCall(ref int X);

class MainClass
{
   public static void Add2(ref int x) { 
       x += 2; 
   }
   
   public static void Add3(ref int x) { 
       x += 3; 
   }

   static void Main(string[] args)
   {
      FunctionToCall functionDelegate = Add2;
      functionDelegate += Add3;
      functionDelegate += Add2;

      int x = 5;
      functionDelegate(ref x);

      Console.WriteLine("Value: {0}", x);
   }
}
Value: 12
