C＃中的线程执行顺序

Question

I have a list of thread I want to ensure the execution order between them this is the code

for (int k = 0; k < RadioList.Count; k++)
{                                     
    for (int i = 0; i < filePaths.Count(); i++)
    {
        Thread t = new Thread(delegate()
        {                                  
            Thread_Encde_function(TempRadio.PublishPoint, filePaths[i], encodingtype);
        });
        t.Start();
        Thread.Sleep(1000);
    }
}

I want to know if thread.join() can do the job.

Answer 1

If your tasks can execute asynchronously (out of order), then threads are appropriate. However, if you have a number of tasks you want to execute in order (strictly one after the other), then why use threads? You should just execute them in your for loop, as they can't be parallelized. Using Thread.Join to wait for the thread right after you start it will do the trick, but that way you will have to wait until a task is finished before starting the next one, effectively executing them in order.

However, if you have some parts of the tasks that can be executed simultaneously, and other parts that have to be sequential, you can take a look at the C# Task Parallel Library , it makes doing things like that easy.
