How to get the total number of days in a year from the given date

Question

I would like to get the total number of days in a year left from the given date .. Assume if a user gives 04-01-2011(MM-DD-YYYY) I would like to find the remaining days left. How to do this..

Answer 1

Perhaps just:

DateTime.IsLeapYear(DateTime.Now.Year) ? 366 : 365

Sorry, read it as if you just wanted the number of days in current year...

Answer 2

should do the trick

int daysLeft = new DateTime(DateTime.Now.Year, 12, 31).DayOfYear - DateTime.Now.DayOfYear;
