首先谢谢上面的,偶有疑问

 if (temp != null)
            {
                temp(this, new System.EventArgs());///为什么到这一句会跑到public void ReceiveTestEvent()这个EventReceiver里面去执行呢？谢谢

            }

[king19840811]

if (temp != null)
{
temp(this, new System.EventArgs());///为什么到这一句会跑到public void ReceiveTestEvent()这个EventReceiver里面去执行呢？谢谢

}

temp就是激活事件，
EventReceiver
public void Subscribe(EventSource source)
{
TestEventDelegate temp = new TestEventDelegate(ReceiveTestEvent);
source.TestEvent += temp;

} 这里订阅了一个事件。
而该事件所调用的方法就是public void ReceiveTestEvent()

还有就是为什么输出System.Console.WriteLine(sender.ToString());//出来的是Sort.EventSource?
要想出来event1怎么办呢?谢谢.

[king19840811]

sender.ToString()是输出当前实例的类型不可能输出event1

谢谢...结贴送分.
