This should work:

DateTime.Now.ToString("hh.mm.ss.ffffff");

If you don't need it to be displayed and just need to know the time difference, well don't convert it to a String. Just leave it as, DateTime.Now();

And use TimeSpan to know the difference between time intervals:

Example

DateTime start;
TimeSpan time;

start = DateTime.Now;

//Do something here

time = DateTime.Now - start;
label1.Text = String.Format("{0}.{1}", time.Seconds, time.Milliseconds.ToString().PadLeft(3, '0'));
