获取从StartDate到EndDate的日期列表

Question

How can i get list of dates between start and end dates using linq or lambda expression.

DateTime StartDate = DateTime.Now;
DateTime EndDate = DateTime.Now.AddMonths(13);
List<DateTime> ListofDates = //Contains list of all dates only between start and end date.

Answer 1

Enumerable.Range(0, (EndDate - StartDate).Days).Select(i => StartDate.AddDays(i))

Answer 2

First of all, when you want Dates and not Datetimes you better use DateTime.Now.Date instead of just DateTime.Now

I've edited SLaks code so you can get the list of dates you want.

DateTime StartDate = DateTime.Now.Date;
DateTime EndDate = DateTime.Now.Date.AddMonths(13);
IEnumerable<double> daysToAdd = Enumerable.Range(0,
                                                (EndDate - StartDate).Days + 1)
                                            .ToList().ConvertAll(d => (double)d);
IEnumerable<DateTime> ListOfDates = daysToAdd.Select(StartDate.AddDays).ToList();

Note that I've added +1 in the enumerable so you can have both the start and end date (you didn't specify it)

Answer 3

List<DateTime> ListofDates = Enumerable.Range(0, (EndDate - StartDate).Days)
                                       .Select(i => StartDate.AddDays(i))
                                       .ToList();
