Could static thread be stopped in Kestrel on Linux without manual abort?

Question

User-1350516731 posted

public class HomeController {

public static Thread Thread = new Thread(new ThreadStart(Work));

public ViewResult Index()
{
if(!Thread.IsAlive && DateTime.Now < new DateTime(2020,12,31))
    Thread.Start()

return View();

}

public static void Work()
{
}

}

What reasons could lead to Thread abort in this piece of code rather than manual server machine stop on Linux if we call Index only once a year?

Hi Alex9 ,

Static threads will not stop by themselves. In general, a thread is stopped :  after running the Work() method, or you call the Abort() method of the thread, or an exception is thrown in the thread.

static variables are initialized on the first reference. so the code

if(!Thread.IsAlive && DateTime.Now < new DateTime(2020,12,31))

the first time Thread.IsAlive is run, it calls the initialization of Thread (poor practice to use a class name as a variable). Your initializer:

public static Thread Thread = new Thread(new ThreadStart(Work));

starts a thread, which exits quickly as it has no code to execute.
