2012.6.10 事件

事件也是 委托事件

和委托用法一样

 

只是赋值的时候只能用 +=

 class Program
    {
        static ShaoShui ss = new ShaoShui();
        static void Main(string[] args)
        {

           // ss.evshaoshui = ss_evshaoshui;

            
            ss.evshaoshui += new SSdelegate(ss_evshaoshui);
            for (int i = 0; i < 100; i++)
            {
                Thread.Sleep(500);
                Console.WriteLine("现在水温是" + (i + 1));
                ss.Jiaore();
            }
            
           
            Console.ReadKey();
        }

        static void ss_evshaoshui()
        {
            Console.WriteLine("水开了");
        }
       
    }
    public delegate void SSdelegate();
  
    public class ShaoShui
    {
        public event SSdelegate evshaoshui;
       // public SSdelegate evshaoshui;
        int n = 0;

        public void Jiaore()
        {
            n++;
            if (n >= 100)
            {
                if (evshaoshui != null)
                {
                    evshaoshui();
                }
            }
        }
    }
