You are limited by the OS not by the programming language.

If you look at the stopwatch class in c#
it talks of a limit of 100 nanoseconds.
I gues this depends on hardware etc.

It should be emphasized that the unit of measurement is
not the same as resolution.

Using QueryPerformanceCounter you can measure to the accuracy of the
processor clock. Note that the act of measuring will add some delay, and if
you have a variable clockspeed (notebook powersave, for example) then your
results won't be very nice.
