Why does DateTime.Now.TimeOfDay.ToString(“HH:mm:ss.ffffff”) throw FormatException?

Question

I\'m having a similar problem with FormatException being thrown. My code is simply:

void Orders_OnSubmit()
{
   DateTime CurrentTime = DateTime.Now;
   rtbAd         


        

Answer 1

TimeOfDay is of type TimeSpan and it has different formatting options than DateTime. You also need to escape the colon (:)

 currentTime.TimeOfDay.ToString("hh\\:mm\\:ss\\.ffffff") 

Your sample tried to use the "HH" format which is defined for DateTime, but not for TimeSpan.
