Sleep in loop when application is running, but sleeps too few

Question

private static void Main(string[] args)
{
    for (;;)
    {
        TemporaryCityTool.TemporaryCityTool.AddCity();
        Console.WriteLine("waiting...");
        Thread.Sleep(3600);
    }
}

why Thread.sleep not working. I am getting message waiting all the time. I want that application will wait 10 minutes then continue again.

Answer 1

Thread.Sleep takes a value in milliseconds, not seconds, so this only tells the current thread to wait 3.6 seconds. If you want to wait 10 minutes, use:

Thread.Sleep(1000 * 60 * 10);  // 600,000 ms = 600 sec = 10 min

This is probably an inappropriate use of Sleep, though. Consider using a Timer instead, so that you get something along the lines of:

// Fire SomeAction() every 10 minutes.
Timer timer = new Timer(o => SomeAction(), null, 10 * 60 * 1000, -1);

See this StackOverflow thread for more details on that.

Answer 2

The argument of the Sleep method is in milliseconds, so if you want to sleep for 10 minutes:

Thread.Sleep(10 * 60 * 1000);

Answer 3

3600 is 3.6 seconds. If you want it to sleep for 10 minutes, you should set it to 600000.

Thread.Sleep(1000 * 60 * 10);  // Milliseconds(1000) * Seconds(60) * Minutes(10)

Which is equal to:

Thread.Sleep(600000);

Answer 4

thrad.sleep is in milli seconds 10 mins would be thread.sleep(1000 * 60 * 10)

Why are you using thread.sleep, you may be better using a timer

Answer 5

10 minutes in milliseconds is 600,000. Your Sleep will only wait 3.6 seconds. It's often clearer to use a timespan:

Thread.Sleep(new TimeSpan(0,10,0));

Answer 6

thx, my big mistake. John Feminella i use thread now.

private static void Main(string[] args)
        {
            Thread thrd1 = new Thread(new ThreadStart(Trmain));

            thrd1.Start();
        }

        private static void Trmain()
        {
            for (; ; )
            {
                Console.WriteLine("waiting 10 minutes...");
                Thread.Sleep(1000 * 60 * 10);
            }
        } 

thx all
