问题描述

我们如何知道对象的引用计数是多少？有时希望计数在释放时等于1，而不是在VB自动释放时为0。

How do we know an object's reference count is how much? Sometimes hope count is equal to 1 on the release, rather than to 0 when released automatically by the VB.

推荐答案

你没有。对象不参考计数;引用计数方案具有循环引用问题，其中两个对象相互引用但是无法访问，因此泄漏。

.NET使用标记和扫描方法，该方法不使用引用计数。 br />

You don't. Objects are not reference counted; reference counting schemes have the circular reference problem, where two objects refer to each other but are otherwise inaccessible and therefore leak.
.NET uses a "mark and sweep" approach which does not use reference counts.
