清除未使用的对象 [英] Clearing out unused objects

问题描述

快速检查-当我想要摆脱一个对象时，我可以将其分配为null并自动进行垃圾收集吗，还是需要做其他事情?例如:

Quick check - when I want to get rid of an object, can I just assign it to null and it'll get garbage-collected automatically, or is there something else that needs to be done? For example:

            List<RandomClass> TestList = new List<RandomClass>();

            for (int x = 0; x<500000;x++)
                TestList.Add(new RandomClass());

            TestList = null;

这样简单就能清除TestList使用的所有资源吗?

Will simply doing this clear out any and all resources TestList was using?

推荐答案

该对象超出范围，因此，只要不是全局对象，您就不必担心它.

The garbage collector will remove any object when the object goes out of scope, so you don't really need to worry about it, so long as an object that's not global.
