在.NET中,在此代码之后,什么机制阻止Thread对象被垃圾回收？

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

是的,可以安全地假设某些东西有对线程的引用,我只是在徘徊究竟是什么.出于某种原因,Reflector没有向我展示System.Threading,所以我不能自己挖掘它(我知道MS发布了.NET框架的源代码,我只是没有它的方便).

我有以下代码(为了便于阅读而减少):

主类:

public StartProcess()
{
    Thinker th = new Thinker();
    th.DoneThinking += new Thinker.ProcessingFinished(ThinkerFinished);
    th.StartThinking();
}

void ThinkerFinished()
{
    Console.WriteLine("Thinker finished");
}

思想家班级:

public class Thinker
{
    private System.Timers.Timer t;

    public delegate void ProcessingFinished();
    public event ProcessingFinished DoneThinking;

    BackgroundWorker backgroundThread;

    public Thinker() { }

    public StartThinking()
    {
        t = new System.Timers.Timer(5000);    // 5 second timer
        t.AutoReset = false;
        t.Elapsed += new System.Timers.ElapsedEventHandler(t_Elapsed);
        t.Start();

        // start a background thread to do the thinking
        backgroundThread = new BackgroundWorker();
        backgroundThread.DoWork += new DoWorkEventHandler(BgThread_DoWork); …
