对垃圾收集器有什么保证？
根据我的研究,我找到了：
>如果仍然存在对内存的引用,则不会对其进行垃圾回收
>如果没有参考：
>当它是GC时是非确定性的
>当GC释放到终结器时,将在释放内存之前运行.
>无法保证终结者的顺序(所以不要假设父母将在孩子之前运行).
但我真正想知道的是：
是否保证所有内存最终都将被垃圾收集并且终结器(析构函数)在对象上运行(假设程序退出很好).例如,最终退出时没有内存压力的应用程序会强制GC查找所有对象并确保调用终结器(析构函数)(包括静态成员变量)？
我确实在这个页面上找到了一个引用：

In addition,by default,Finalize methods are not called for unreachable objects when an application exits so that the application may terminate quickly.
但我不确定这句话是多么权威.
我还找到了以下文档：
CriticalFinalizerObject
Is there a guarantee that all memory
will eventually be garbage collected
and the finalizer (destructor) run on
the object (assuming the program
exited nicely).
不可以.从Object.Finalize文档中可以清楚地看出,如果使用终结器,则不会调用终结器
>其他一些终结器无法正常完成：
Another finalizer blocks indefinitely
(goes into an infinite loop,tries to
obtain a lock it can never obtain and
so on). Because the runtime attempts
to run finalizers to completion,other
finalizers might not be called if a
finalizer blocks indefinitely.
>其他一些终结者创造更多
制作它的最终目标
不可能完成所有
可终结的对象：
The runtime continues to Finalize
objects during shutdown only while the
number of finalizable objects
continues to decrease.
>其他一些终结者抛出异常：
If Finalize or an override of Finalize
throws an exception,and the runtime
is not hosted by an application that
overrides the default policy,the
runtime terminates the process and no
active try-finally blocks or
finalizers are executed. This behavior
ensures process integrity if the
finalizer cannot free or destroy
resources.
话虽这么说,除非有必要,否则你有更多理由不想使用终结器.
