C# 委托事件

一.委托

    GreetingDelegate delegate1;//声明委托    delegate1 = EnglishGreeting; // 先给委托类型的变量赋值    delegate1 += ChineseGreeting;   // 给此委托变量再绑定一个方法    // 将先后调用 EnglishGreeting 与 ChineseGreeting 方法    delegate1 ("Jimmy Zhang");  

二.事件

cs1： 声明部分：

    private int numAgo=0;    public delegate void GetNumDelegate(int num);    public GetNumDelegate GetNumEvent;

            numAgo++;

            //注册事件后执行            if (GetNumEvent != null)            {                GetNumEvent(numAgo);            }

 

cs2：调用部分：

FunCodeLineCounter funCodeLineCounter = new FunCodeLineCounter();

funCodeLineCounter.GetNumEvent += GetAgoNumFile;

        public void GetAgoNumFile(int num)        {            toolStripStatusLabel1.Text = "当前读取第"+num+"个文件";                   }
