How can I make a delay inside my “for loop”?

Question

How can I write a code to make a delay at the end of my “for loop” to make e.g. 1 millisecond delay before going through the next loop?

I don't think you can add a delay of 1 ms accurately , you may see this similar question for adding delay http://stackoverflow.com/questions/5449956/how-to-add-a-delay-for-a-2-3-seconds?answertab=votes#tab-top — Habib, Feb 24 '14 at 16:53
For such a small time delay (1ms) I'd probably use a spinner in conjunction with a `Stopwatch`. — Nick Gotch, Feb 24 '14 at 19:03

Thread.Sleep(1) will wait for at least 1 millisecond. More realistically it will sleep for about 16ms, as it gives up your thread's time slice and something else will get to run for a full time slice before it can resume.

Try using Thread.Sleep(1)

The input parameter for Thread.Sleep is the millisecond delay you want.

You can use

Try{
Thread.Sleep(1);
}Catch(Exception e){
}

Why the try catch call? Can a Thread.Sleep() call cause an exception on its own? – Chris Schiffhauer Feb 24 '14 at 17:03

i can't use thread as it will terminate the whole programme. but i just need to put delay in part of my programme. how can i make a delay function plz? – CowBoy Feb 24 '14 at 17:06
why ? i mean why it will terminate the whole code? if u'll handle it in catch clause it will work smoothely.. – Ashish Ratan Feb 24 '14 at 17:09
another way, u can also use a free for loop till 1000 steps before executing your second loop – Ashish Ratan Feb 24 '14 at 17:12
it will give little delay in computation... – Ashish Ratan Feb 24 '14 at 17:13

If you need to avoid the Thread class, and are using .NET 4.5 asynchronously, you can use the following:

await Task.Delay(1);
