Please clarify what you are trying to accomplish.

Hi Mark, I thought that i got properly what exactly OP wants from his actual question therefore I answered here.
What I got from his eg. is all he wants the days between two days, I agree with your comment that question he mentioned and actually ask'd is far different. But I just tried to solve what he ask'd with actual example.

Why are you answering? The question was for the OP to clarify not for you to make assumptions about what they wanted. I'm glad you can read minds and know exactly what was asked for.

Solution 1

Try this: From this link[^]

C#

public static int Weekdays(DateTime dtmStart, DateTime dtmEnd)
    {
        // This function includes the start and end date in the count if they fall on a weekday
        int dowStart = ((int)dtmStart.DayOfWeek == 0 ? 7 : (int)dtmStart.DayOfWeek);
        int dowEnd = ((int)dtmEnd.DayOfWeek == 0 ? 7 : (int)dtmEnd.DayOfWeek);
        TimeSpan tSpan = dtmEnd - dtmStart;
        if (dowStart <= dowEnd)
        {
            return (((tSpan.Days / 7) * 5) + Math.Max((Math.Min((dowEnd + 1), 6) - dowStart), 0));
        }
        return (((tSpan.Days / 7) * 5) + Math.Min((dowEnd + 6) - Math.Min(dowStart, 6), 5));
    }

Tests (each test returns 5):

C#

int ndays = Weekdays(new DateTime(2009, 11, 30), new DateTime(2009, 12, 4));
   System.Console.WriteLine(ndays);

   // leap year test
   ndays = Weekdays(new DateTime(2000, 2,27), new DateTime(2000, 3, 5));
   System.Console.WriteLine(ndays);

   // non leap year test
   ndays = Weekdays(new DateTime(2007, 2, 25), new DateTime(2007, 3, 4));
   System.Console.WriteLine(ndays);

Solution 2

This should work fine for you

DateTime date = DateTime.Now;
long dateAsLong = date.ToFileTime();
DateTime orgDate = DateTime.FromFileTime(dateAsLong);

Or

DateTime mydate = new DateTime( 1970, 1, 1, 0, 0, 0, 0 );
long mL64 = mydate.Ticks;
