学习委托

using System; //无参数的委托

namespace ConsoleApp1
{
    class Program
    {

        delegate void MyDel();

        public void Print1()
        {
            Console.WriteLine("I am print 1");
        }

        public void Print2() { Console.WriteLine("I am print 2"); }

        static void Main(string[] args)
        {
          
            Program program = new Program();

            MyDel myDe = program.Print1;
            myDe += program.Print2;

            myDe();

            Console.ReadKey();

 

        }
    }
}
