C# time in microseconds

You can use "ffffff" in a format string to represent microseconds:

Console.WriteLine(DateTime.Now.ToString("HH:mm:ss.ffffff"));

To convert a number of ticks to microseconds, just use:

long microseconds = ticks / (TimeSpan.TicksPerMillisecond / 1000);

If these don't help you, please provide more information about exactly what you're trying to do.

EDIT: I originally multiplied ticks by 1000 to avoid losing accuracy when dividing TimeSpan.TicksPerMillisecond by 1000. However, It turns out that the TicksPerMillisecond is actually a constant value of 10,000 - so you can divide by 1000 with no problem, and in fact we could just use:

const long TicksPerMicrosecond = 10;

...

long microseconds = ticks / TicksPerMicrosecond;

I was unable to get Johns tick to micorosecond conversion to work. Here is how I was able to measure Microsecond and Nanosecond resolution by using ticks and the Stopwatch:

Stopwatch sw = new Stopwatch();
sw.Start();

// Do something you want to time

sw.Stop();

long microseconds = sw.ElapsedTicks / (Stopwatch.Frequency / (1000L*1000L));
long nanoseconds = sw.ElapsedTicks / (Stopwatch.Frequency / (1000L*1000L*1000L));

Console.WriteLine("Operation completed in: " + microseconds + " (us)");
Console.WriteLine("Operation completed in: " + nanoseconds + " (ns)");

"ffffff" is what you need.

return DateTime.Now.ToString("HH:mm:ss.ffffff");
