循环引用的含义。 [英] Implications of circular references.

问题描述

我在同一个项目中的2个类之间有一个循环引用（即

每个类指的是另一个）。该应用程序运行良好，我没有看到

问题，这让我感到惊讶。


是否有任何我没有看到的问题（性能明智或垃圾

收集明智）带循环引​​用？


谢谢。

解决方案

我在.NET中知道的唯一循环引用问题是

程序集。 .NET不允许不同程序集中的类

相互引用。


除此之外，没问题。

绕过循环引用问题是.NET使用的垃圾收集算法的优点之一

计算

计划。如果这两个对象都没有可用，那么它们都可以用来获得
GC''d。

我知道你不能在

集会之间进行循环引用。我想知道的是，如果单个程序集中的

对象之间存在循环引用，我是否会（可能需要很难解决）问题。

I have a circular reference between 2 classes in the same project (i.e.
each class refers to the other). The app runs fine and I am seeing no
issues, which kind of surprised me.

Are there any issues that I am not seeing (performance wise or garbage
collection wise) with circular references?

Thanks.

解决方案

The only circular reference issues I know of in .NET are between
assemblies. .NET doesn''t allow classes in different assemblies to
mutually reference each other.

Other than that, no problem.

Getting round the circular references problem is one of the benefits of
the garbage collection algorithm .NET uses over a reference counting
scheme. If neither object is reachable, they''re both available to be
GC''d.

I know about the fact that you can''t do circular refs between
assemblies. What I am wondering is whether I''ll have (possibly
difficult to troubleshoot) issues if there are circular refs between
objects in a single assembly.
