C # Create a thread After the thread is processed, use return to return, but the system handle is not released at all. O

Return is the natural end, the key is to release unmanaged objects before return. Abort is the abnormal end in the main thread.

I tested and found that the oService.SocketRun () function does not release the handle even if it returns immediately without writing any code.

I haven't tried the "call GC.Collect ()" method, but it is strange if you call GC.Collect continuously in the main thread.

The handle will be reclaimed after the instance osThread is confirmed to be invalid. You can throw events to the main thread before the end of the oService.SocketRun method, end the thread on the main thread (note the synchronization Invoke), and only forcefully recycle osThread. ).

Don't worry about this, the system will automatically recycle,
Microsoft's automatic recycling is used for this purpose

After the thread runs, it will be automatically recovered. Originally, these tasks are not yours to manage.
osThread = null;
GC.Collect ();

Originally, the system will manage things by itself, but it has to be done by myself. I don't think it makes much sense ..

personal opinion for reference only..

In fact, I think this is normal.It is not the end of the thread, the handle will disappear immediately.
Here is my opinion:
The thread has its own counter and its own context. When the technical device = 0, the system will release resources. Note that it is system management, so there is also some time. We can often see the 3 states of the thread when we read the os book. There is a state called the zombie state, which is the zombie process under Linux. It means that it is over, but the system has not released resources, and its lifetime is this period of time. Windows is a multi-threaded model, its threads and unix The following processes are basically the same.

Your return just means that you gave up the right to act on the thread, the effect at this time is that the counter will be -1. Nothing else
