是什么阻止了 C# 中的线程被收集?

问题描述

在 .NET 中，在这段代码之后，什么机制可以阻止 Thread 对象被垃圾回收?

In .NET, after this code, what mechanism stops the Thread object from being garbage collected?

new Thread(Foo).Start();
GC.Collect();

是的，假设 something 引用了该线程是安全的，我只是在徘徊到底是什么.由于某种原因，Reflector 没有向我显示 System.Threading，所以我自己无法挖掘它(我知道 MS 发布了 .NET 框架的源代码，我只是手边没有它).

Yes, it's safe to assume something has a reference to the thread, I was just wandering what exactly. For some reason Reflector doesn't show me System.Threading, so I can't dig it myself (I know MS released the source code for the .NET framework, I just don't have it handy).

推荐答案

运行时只要线程在运行就保持对线程的引用.只要有人仍然保留该引用，GC 就不会收集它.

The runtime keeps a reference to the thread as long as it is running. The GC wont collect it as long as anyone still keeps that reference.
