這個為什麼報錯。

using System;





namespace myevent

{

public delegate void mydelegate(mystruct aa);

public struct mystruct

{

public int id;

public string name;

}

public class A

{

// private mydelegate m_Handler = null;



public event mydelegate myevent;



}

class Program

{

static void Main(string[] args)

{

mystruct mys = new mystruct();

mys.id = 100;

mys.name = "my name";

A myA = new A();

myA.myevent += new mydelegate(myA_myevent);//error???



}



public void myA_myevent(mystruct aa)

{

Console.WriteLine("用戶ID：{0},用戶名：{1}", aa.id, aa.name);

}

}





}

我剛剛試了下你的代碼，程序都沒反應，也沒報錯
你代碼連事件都沒觸發

[majingshuai]

myA.myevent += new mydelegate(myA_myevent);这句话错了
　　　委托后面的参数不对

[kingvsliuzhi]

using System;

namespace myevent

{

public delegate void mydelegate(mystruct aa);

public struct mystruct

{

public int id;

public string name;

}



public class A

{

public event mydelegate myevent;

}

class Program

{

static void Main(string[] args)

{

mystruct mys = new mystruct();

mys.id = 100;

mys.name = "my name";

A myA = new A();

Program p = new Program();//為什么要加這個？ 在這里做什么用？謝謝

myA.myevent += new mydelegate(p.myA_myevent);

//請教此時如何去觸發myevent 事件？（此處就當不知道 class A里的東西 如：A就是一個窗體對象,可以實現嗎？ ） 謝謝

//mydelegate myhander = new mydelegate(p.myA_myevent);

//myhander(mys);

Console.Read();

}

public void myA_myevent(mystruct aa)

{

Console.WriteLine("用戶ID：{0},用戶名：{1}", aa.id, aa.name);

Console.Read();

}

}



}

頂。。。

Program p=new Program();加這個是什麼意思了？
