线程可以在App终止后存活吗

Question

If a .NET program creates and starts a System.Threading.ThreadPool thread, and then the program ends (either naturally or by crashing):

• Is it possible for the Thread to survive and carry on processing on its own?
• Is it possible that an App will look like it has terminated due to the main UI thread having ended, but for a background thread to carry on running invisibly?

Answer 1

根据定义，如果进程的其中一个线程仍在工作，那么它实际上并没有结束 。

Answer 2

一个线程不能独立于一个进程生存，所以没有。

Answer 3

No. And from the horse's mouth (MSDN)

The threads in the managed thread pool are background threads. That is, their IsBackground properties are true. This means that a ThreadPool thread will not keep an application running after all foreground threads have exited.
