How would the main thread knows if a Worker Thread is still running

[microkarl]

Hi, I have a question on multithreading, is there a way for the main thread to know how many, if any, worker thread(s) is still running in the background.

Depends on whether you can still access that specific thread. If you have the Thread object that represents the thread, you can use the IsAlive property to see if it is still alive (and thus running).

More concretely, create an ArrayList or Array to keep track of the threads and check the IsAlive Property

 

ArrayList workerThreads = new ArrayList();

 

//create threads

System.Threading.Thread th = new System.Threading.Thread(new ThreadStart(someFunc);

 

workerThreads.Add(th);

 

foreach (object obj in workerThreads)

{

System.Threading.Thread tempThread = (System.Threading.Thread)obj;

Console.WriteLine(tempThread.IsAlive.ToString());

}

 

//something as such
