C# sub millisecond timing

Is there anywhere in C# to perform timing operations with sub millisecond accuracy? I'm putting timing code in my software and everything is being returned as 0ms. I would like to know if there is a way of getting even finer granularity.

Addendum: is this the correct code to get sub开发者_StackOverflow社区 millisecond timing?

timeSpan.TotalMilliseconds / 10

I'm still getting 0 as the elapsed time

You could always try using QueryPerformanceCounter or the StopWatch class for a managed approach

Use System.Diagnostics.Stopwatch

---

Usually I measure these kinds of scenarios by repeating the operation multiple times (as many as needed to get the milliseconds over a few dozen or hundred.

Then you can adjust and measure more easily.

You could try measuring your performance in matter of Ticks instead of milliseconds. It will be much more accurate in terms of performance.

but I agree with Sam and Tyranid, use System.Diagnostics.StopWatch.

I learned something new. Those Ticks are handy indeed. Complete example:

Stopwatch stopwatch = Stopwatch.StartNew();

// Run code to get duration of

long durationInTicks = stopwatch.ElapsedTicks;
Console.WriteLine($"Duration: {(decimal)durationInTicks / TimeSpan.TicksPerMillisecond:f3}ms");

You can also use stopwatch.ElapsedTicks inside the Console.WriteLine, but I do not know if that has any performance delays, that's why I first retrieve it and put it in a variable.
