关于处理对象删除处理程序 [英] Remove handlers on disposing object

问题描述

我能想到的一些凌乱的方式来解决这个问题，但它让我觉得应该有一个更优雅的解决方案比那些我已经想出。

什么是一个对象之前，清理所有的事件处理程序的本身被设置最合适的方式。这是一个耻辱的事件处理程序将不可枚举。

在理论上，是它认为更正确的code添加处理程序的对象要记得删除它不是假设的对象将自身清洁之前它超出范围？

要对上述问题，我会说是的。有关事件的基本原理是，事件射手不应该负责管理自己的处理程序;谁添加的事件应该做清理工作。

I can think of a few messy ways to solve this, but it strikes me that there should be a far more elegant solution than those which I've already come up with.

What's the most appropriate way for an object to cleanse itself of all of its event handlers prior to being disposed. It's a shame the event handler can't be enumerated upon.

In theory, is it considered more correct for the code adding the handler to an object to remember to remove it than assuming the object will clean itself up before it goes out of scope?

解决方案

To the above question, I'll have to say yes. The basic theory about events is that the event firer shouldn't be responsible for managing its own handlers; whoever added the event should do cleanup.
