Time delay in For loop in c#

Question

how can i use a time delay in a loop after certain rotation? Suppose:

for(int i = 0 ; i<64;i++)
{
........
}

i want 1 sec delay after ea

Answer 1

Once I needed to write a program witch was so sensitive and needed accurate timing (about Nano seconds).

I used all sorts of stuff like Thread.Sleep(), Timer and... but none of them was that accurate that could answer my needs so I used this code for delaying:

var stopWatch = new Stopwatch();
for(int i = 0 ; i<64;i++)
{
stopWatch.Restart();
while (stopWatch.ElapsedMilliseconds <= 1000)
{

}
}

Of course this way is not very CPU friendly, yet when you need accuracy that much you have to go old school.
