删除匿名事件处理程序 [英] Removing anonymous event handlers

问题描述

可能重复：

C＃：如何删除lambda事件处理程序

是否可以删除作为匿名函数附加的事件处理程序？假设我有一个事件，我以这种方式订阅：

Is it possible to remove an event handler which was attached as anonymous function? Let's say I have an event, and I subscribe to it in this way:

TestClass classs = new TestClass ();
classs.myCustomEvent +=  (a,b) => { Console.Write(""); };

是否可能以某种方式删除此eventHandler？

Is it possible somehow to remove this eventHandler using -= ??

推荐答案

有可能，但您需要先将其存储在本地变量中：

It is possible, but you need to store it in a local variable first:

MyDelegate handler = (a, b) => { Console.Write(""); };
class.myCustomEvent += handler;
class.myCustomEvent -= handler;
