如何取消注册“匿名"事件处理程序 [英] How do I Unregister 'anonymous' event handler

问题描述

说我是否在监听一个事件:

Say if I listen for an event:

Subject.NewEvent += delegate(object sender, NewEventArgs e)
{
    //some code
}); 

现在如何取消注册此事件?或者只是让内存泄漏?

Now how do I un-register this event? Or just allow the memory to leak?

推荐答案

如果您需要取消注册事件，我建议避免事件处理程序的匿名委托.

If you need to unregister an event, I recommend avoiding anonymous delegates for the event handler.

这是将它分配给本地方法更好的一种情况 - 您可以完全取消订阅事件.

This is one case where assigning this to a local method is better - you can unsubscribe from the event cleanly.
