Dùng DateTime.Ticks. Một tick đại diện 1 trăm nano giây.

using System;

namespace ConsoleApplication2
{
    class Program
    {
        static void Main(string[] args)
        {
            try
            {
                long startTick = DateTime.Now.Ticks;
                long endTick = DateTime.Now.Ticks;
                long tick = endTick - startTick;
                long seconds = tick / TimeSpan.TicksPerSecond;
                long milliseconds = tick / TimeSpan.TicksPerMillisecond;
                long microseconds = tick / 10;
                Console.WriteLine("Seconds Elapsed :" + seconds);
                Console.WriteLine("Millseconds Elapsed :" + milliseconds);
                Console.WriteLine("Microseconds Elapsed :" + microseconds);
                Console.ReadLine();
            }
            catch (Exception ex)
            {
                // handle ex
            }
        }
    }
}
