He creado un programa ficticio muy simple para comprender Delegados y eventos. En mi programa a continuación, simplemente llamo a un método. Cuando llamo a un método, se llaman automáticamente cinco métodos con la ayuda de delegados y eventos.

Eche un vistazo a mi programa y hágame saber dónde estoy equivocado o correcto, ya que esta es la primera vez que uso delegados y eventos.

using System;

namespace ConsoleApplication1
{
    public delegate void MyFirstDelegate();

    class Test
    {
        public event MyFirstDelegate myFirstDelegate;

        public void Call()
        {
            Console.WriteLine("Welcome in Delegate world..");
            if (myFirstDelegate != null)
            {
                myFirstDelegate();
            }
        }        
    }

    class AttachedFunction
    {
        public void firstAttachMethod()
        {
            Console.WriteLine("ONE...");
        }
        public void SecondAttachMethod()
        {
            Console.WriteLine("TWO...");
        }
        public void thirdAttachMethod()
        {
            Console.WriteLine("THREE...");
        }
        public void fourthAttachMethod()
        {
            Console.WriteLine("FOUR...");
        }
        public void fifthAttachMethod()
        {
            Console.WriteLine("FIVE...");
        }
    }

    class MyMain
    {
        public static void Main()
        {
            Test test = new Test();
            AttachedFunction attachedFunction = new AttachedFunction();
            test.myFirstDelegate += new MyFirstDelegate(attachedFunction.firstAttachMethod);
            test.myFirstDelegate += new MyFirstDelegate(attachedFunction.SecondAttachMethod);
            test.myFirstDelegate += new MyFirstDelegate(attachedFunction.thirdAttachMethod);
            test.myFirstDelegate += new MyFirstDelegate(attachedFunction.fourthAttachMethod);
            test.myFirstDelegate += new MyFirstDelegate(attachedFunction.fifthAttachMethod);

            test.Call();
            Console.ReadLine();
        }
    }
}
