有没有办法做到在CLR一个WeakList或WeakCollection（如WeakReference的）？ [英] Is there a way to do a WeakList or WeakCollection (like WeakReference) in CLR?

问题描述

使用名单，其中，WeakReference的＆GT; 将无法工作，因为我想要的。我想要的是在WeakReferences是自动的从列表中删除的时，他们引用的对象被垃圾回收。

Using a List<WeakReference> will not work as I want. What I want is for WeakReferences to be automatically removed from the list whenever the object they reference is garbage collected.

ConditionalWeakTable＆LT; TKEY的，TValue＆GT;！不满足我要么，因为虽然它的键和值是弱引用和收藏价值，不能一一列举。

ConditionalWeakTable<TKey,TValue> does not satisfy me either, because although its keys and values are weakly referenced and collectable, you cannot enumerate them!

推荐答案

我同意实施 WeakList＆LT; T＆GT; 是可能的，但我不认为这是完全轻松的。欢迎你来这里使用我的实现。该 WeakCollection＆LT; T＆GT; 类依赖于<一href="http://nitokitchensink.$c$cplex.com/SourceControl/changeset/view/51391#1006414"><$c$c>WeakReference<T>,而这又取决于<一href="http://nitokitchensink.$c$cplex.com/SourceControl/changeset/view/51391#1006416"><$c$c>SafeGCHandle.

I agree that implementing a WeakList<T> is possible, but I don't think it's exactly easy. You're welcome to use my implementation here. The WeakCollection<T> class depends on WeakReference<T>, which in turn depends on SafeGCHandle.
