What is the 'Subtract Days' equivalent of DateTimePicker.Value.AddDays()? : <p>I have a DateTimePicker and two buttons on a form. The buttons are intended to allow a user to cycle backwards and forwards through the dates displayed in the picker.</p>

<p>The code DateTimePicker.Value.AddDays(1); increments the value displayed and DateTimePicker.Value.AddDays(-1); decrements it. It seems a bit clunky to me but this works as expected, is passing in a value of -1 the correct way to decrement the displayed date?</p>

<p>Why isn't there a SubtractDays() method?  </p>
