Are Stopwatch.ElapsedTicks and Stopwatch.Elapsed.Ticks always the same?

What does ElapsedTicks and Elapsed.Ticks in the Stopwatch class mean? When could the meaning be different than intended?

Solution

  • I just found out that ElapsedTicks in the Stopwatch class doesn't mean real "ticks" if StopWatch.IsHighResolution is true.

    Note (if IsHighResolution is True - from Microsoft Connect link (now dead)):

    Stopwatch ticks are different from DateTime.Ticks. Each tick in the DateTime.Ticks value represents one 100-nanosecond interval. Each tick in the ElapsedTicks value represents the time interval equal to 1 second divided by the Frequency.

    You can do the math above or it seem you can use StopWatch.Elapsed.Ticks instead of StopWatch.ElapsedTicks.
