Thread.Abort（）最后阻止 [英] Thread.Abort() and finally block

问题描述

假设我有一个childThread当前正在运行一个finally块来

清理外部资源。同时主线程调用

childThread.Abort（）。问题是：当抛出ThreadAbortException

时，childThread是否完成了

finally块中的剩余代码？

Say I have a childThread currently is running a finally block to
cleanup external resources. At the same time the main thread calls
childThread.Abort(). The question is: when the ThreadAbortException
is thrown, does the childThread finish the remaining code in the
finally block?

进行实验。

这是找到这类问题答案的最佳方法。

编写一个简单的代码模型，看看它的作用。

即有一个线程在最后一个块中休息10秒，然后

然后打印一些消息。然后让主线程启动它，等待2秒

并中止它。看看邮件是否被打印出来。


离开我的头顶，没有编写和运行上面的例子，

我相信答案是不 ;。即，最后块将无法完成。

Do the experiment.
This is the best way to find answer to such kind of questions.
Write a simple piece of code the models the situation and see what it does.
I.e. have a thread that sleeps for, say, 10 seconds in the final block and
then prints some message. Then have main thread start it, wait 2 seconds
and abort it. See if the message gets printed.

Off the top of my head, without writing and running the above example,
I believe the answer is "no". I.e., "finally" block will not be completed.

保证finally块被调用。这条规则很少有例外。
。线程中止不是其中之一。

The finally block is guaranteed to be called. There are very few exceptions
to this rule. Thread aborts aren''t one of them.

这是找到这类问题答案的最佳方法。
在模型中编写一段简单的代码，看看

的作用。即有一个线程在最后一个块中睡了10秒，然后打印一些消息。然后让主线程启动它，等待2秒
并中止它。看看消息是否被打印出来。

在我没有编写并运行上述示例的情况下，我不相信，答案是不。即，最后阻止将无法完成。

来自帮助文件：

"在线程中止之前执行Unexcucuted finally块;这个

包括抛出异常时执行的任何finally块。
