何时循环引用存在.NET垃圾回收器问题 [英] A Question about the .NET garbage collector when cyclic references exist

问题描述

我知道，.NET垃圾回收器检测到循环引用，但我不知道循环引用是否可能会导致物体停留需要更长的时间。

I'm aware that the .net garbage collector detects cyclic references but I was wondering whether cyclic references may cause objects to stay longer than necessary.

我在我的ASP.NET应用程序中的循环引用（希望的一对性能方面的原因），我可以与脱身？

I have a cyclic reference in my ASP.NET app (an intended one for performance related reasons), can I get away with that?

推荐答案

它并不需要的CLR不再删除比非循环引用循环引用。 CLR使用技术来收集垃圾的组合。快速的版本，虽然是它植根于所有对象（在栈上的对象，或具有较强的GC手柄举行）开始。任何对象，它是从访问这些对象是活的。任何东西都不会被收集。循环引用不会影响该算法比其他CLR的结果，有一定要检查他们，而不是走在圈子

It doesn't take the CLR any longer to remove a cyclic reference than a non-cyclic reference. The CLR uses a combination of techniques to garbage collect. The quick version though is it starts with all rooted objects (objects on the stack, or held with a strong GC handle). Any object that is reachable from these objects is alive. Anything else will be collected. A cyclic reference won't affect the results of this algorithm other than the CLR has to make sure to check for them and not walk in circles
