在多线程应用程序中中止线程时的内存状态

Question

I didn't find a relevant search hit about what will happen to the memory a thread is using when is it being aborted, if it is a multi-threaded application.

Will there will any memory leak?

Also, if I didn't call Thread.ResetAbort() in catch clause will exception ThreadAbortException be thrown to the outer catch and outer catch if any...

Thanks.

• Threads do not use memory. Processes have memory. Threads run in their parent process.

• In C# objects allocated by an object are not different depending which thread has allocated them. Read up on garbage collection.

Also, if I didn't call Thread.ResetAbort() in catch clause will exception ThreadAbortException be thrown to the outer catch and outer catch if any...

There is something called a documentation and this is a VERY simple lookup there. Let me quote for you. All I did was type "ThreadAbortException" into google, which leads me to

https://msdn.microsoft.com/en-us/library/system.threading.threadabortexception%28v=vs.110%29.aspx?f=255&MSPPError=-2147217396

Now the quote:

When a call is made to the Abort method to destroy a thread, the common language runtime throws a ThreadAbortException. ThreadAbortException is a special exception that can be caught, but it will automatically be raised again at the end of the catch block. When this exception is raised, the runtime executes all the finally blocks before ending the thread. Because the thread can do an unbounded computation in the finally blocks or call Thread.ResetAbort to cancel the abort, there is no guarantee that the thread will ever end. If you want to wait until the aborted thread has ended, you can call the Thread.Join method. Join is a blocking call that does not return until the thread actually stops executing.

Simple like that. It automatically is rethrown at the end of the catch.
