multicast delegate

I think a better explanation is this:
The multicast delegate as a container that can store a lot of the same type.

using System;
namespace MulticastDelegate
{
    delegate  void SI_Deletegate();
    class Person
    {
        private string _name;
        private string _country;
        public Person(string name,string country)
        {
            this._name = name;
            this._country = country;
        }


        public void SelfIntroduction()
        {
            Console.WriteLine(_name+" is come from "+_country);
        }
    }
    class Program
    {
        static void Main(string[] args)
        {
            Person A = new Person("Ken","Hong Kong");
            Person B = new Person("Jumn","England");
            Person C = new Person("Mary","India");
            SI_Deletegate a = new SI_Deletegate(A.SelfIntroduction);
            SI_Deletegate b = new SI_Deletegate(B.SelfIntroduction);
            SI_Deletegate c = new SI_Deletegate(C.SelfIntroduction);


            SI_Deletegate sid = null;
            Console.WriteLine("Start self introduction...");
            sid = a + b;
            sid += c; // the use "+="  symbol  add function
            sid();
            Console.WriteLine("\nAfter removal.");
            sid -= c; // the use "-="  symbol Remove function
            sid();      
        }
    }
}
