距离今天数周

Question

我将来有个约会，我想知道这有几周的路程。

Answer 1

(futureDate - DateTime.Today).TotalDays / 7

Answer 2

I think you'd be best getting the no of days and dividing that by 7

DateTime start = DateTime.Now;
DateTime end = DateTime.Now.AddDays(21);

double noOfDays = (end - start).TotalDays;
double noOfWeeks = noOfDays  / 7;
