怎么死锁？ [英] How did it dead lock?

问题描述

有时我的程序会停止，当我打破它时，我看到2个线程

等待锁定语句试图锁定同一个对象。如果我看起来这些线程的调用堆栈中没有任何其他调用来锁定

语句，所以我不知道它是如何可能的什么都可以上锁。


有人能解释一下吗？


谢谢

解决方案

是否有可能是你刚才提到的另一个线程

持有锁？

您好，

我不这么认为，没有任何其他线程的源代码

可用

你刚刚提到的另外一个线程是否可以锁定？

如果你试图锁定（这）然后它可以导致死锁。你尝试使用SOS / Windbg确定死锁和堆栈跟踪吗？

还发布了一个代码。

Hi,
Sometimes my program stops and when I break it I see 2 threads both
waiting at a lock statement trying to lock the same object. If I look
up the call stack of these threads there aren''t any other calls to lock
statements so I don''t see how it''s possible for anything to be locked.

Can anyone explain this to me?

Thanks

解决方案

Hi,

Is it possible that another thread other than the 2 you just mentioned
is holding the lock?

Hello,

I don''t think so, there aren''t any other threads with source code
available

If you are trying to lock(this) then it can lead in to dead locks. Did
you try using SOS/Windbg to identify the dead lock and the stack trace?
Also post a smaple code.
