Get the number of days between two different DateTime objects

Question

How can I get the difference between days between two DateTime objects?

private static string DaysAfterAYear(DateTime initialDate)
{
    DateTime endDate = initialDate.AddYears(1);
    endDate = endDate.AddMonths(1);
    return ??
}

I need to get the difference between initialDate and endDate.

Answer 1

Use the subtraction method:

static void Main(string[] args)
{
    DateTime begin = DateTime.Now;
    DateTime end = begin.AddYears(1).AddMonths(1);
    var result = end.Subtract(begin).TotalDays;
}

Answer 2

DateTime dt1 = new DateTime(2011,01,01);
DateTime dt2 = new DateTime(2011,01,20);
int ireturn = (int)dt2.Subtract(dt1).TotalDays;

Answer 3

DateTime start = DateTime.Now;
DateTime end = DateTime.Now.AddDays(5);
TimeSpan span = end.Subtract(start);
return span.Days;

Answer 4

        int days = 10;
        DateTime initialDate = DateTime.Now;
        DateTime endDate = DateTime.Now.AddDays(days);
        TimeSpan duration = endDate.Subtract(initialDate);

span.Days, span.TotalDays, TimeSpan. TotalHours vs Hours, , , .

Hours - , , days ( ), Total hours - TimeSpan, .

Answer 5

DateTimes TimeSpan:

var elapsedDays = (endDate - initialDate).TotalDays;
