如何阻止垃圾收集器 [英] How to stop garbage collector

问题描述

C＃中是否有办法阻止垃圾收集器自动杀死我们的对象

。我想自己杀死它？


有没有这样做？

谢谢

解决方案

我忘了问这个场景中发生了什么。


ArrayList first = new ArrayList（）;


ArrayList second = first


first.Dispose（ ）


剂量这三行代码使得第二个无用的变量没有

在哪里？


谢谢

这里有几点需要注意。


1.你在结束时错过了一个分号第二行和第三行，所以

你不会编译=）

2. ArrayList对象没有Dispose方法。

3.假设你把它设置为null，first那么确实会是

null，但是第二是仍然是ArrayList实例。基本上，

你正在从第一个删除指针。对象。该对象不会被破坏/收集/无论如何，因为第二现在有一个参考

它。


此外，垃圾收集器不被称为对象抢夺者。有一个原因。
它只会收集垃圾（你不会使用的空间），而不是你还在使用的东西。

希望这会有所帮助，

ArrayList second = first

first.Dispose（）

Is there a way in C# to stop garbage collector from killing our object
automatically.I''d like to kill it myself??

Is there away to to do so?
Thanks

解决方案

I forgot to ask what happenes in this scenario.

ArrayList first = new ArrayList();

ArrayList second = first

first.Dispose()

Dose these three lines of code makes second a useless variable poiting to no
where?

Thanks

A couple of things to note here.

1. You''re missing a semicolon at the end of the second and third lines, so
you won''t compile =)
2. The ArrayList object doesn''t have a Dispose method.
3. Assuming instead that you set it to null, "first" would then indeed be
null, but "second" would still be the ArrayList instance. Essentially,
you''re removing the pointer from "first" to the object. The object doesn''t
get destroyed/collected/whatever, because "second" now has a reference to
it.

Also, the garbage collector isn''t called "the object snatcher" for a reason.
It''s only going to collect garbage (space you aren''t using), not stuff that
you are still using.

Hope this helps,
