date range

[jellybeannn]

Hi, I've got a date range between a start and end date, which has to be each month on the valuation day,

but if end date(2010/07/20) is before the valuation date(2010/07/31), the valuation month for that month must be displayed.

if (endDate.Day < validDay) is true, then it works perfect. but if it's false, it duplicates all of the fields.

I tried this in my code:

public List<DateTime> GetDates(DateTime startDate, DateTime endDate, int validDay)
    {
        TimeSpan span;
        span = endDate - startDate;

        List<DateTime> result = new List<DateTime>();

        DateTime dateToParse = DateTime.MinValue + span;

        int yearMonths = 0;
        if (dateToParse.Year > 0)
        {
            yearMonths = (dateToParse.Year - 1) * 12;
        }

        int monthCount = (yearMonths + dateToParse.Month) - 1;

                  // ************* Here is the problem
        int lastRow = 0;
        if (endDate.Day < validDay)
            lastRow = (monthCount + 1);
        else
            lastRow = monthCount;

        for (int i = 0; i < lastRow; i++)
        {
            DateTime currDate = endDate.AddMonths(-(monthCount - i));
            int lastDayOfMonth = DateTime.DaysInMonth(currDate.Year, currDate.Month);
            currDate = new DateTime(currDate.Year, currDate.Month, lastDayOfMonth);
            if (endDate.Day > validDay)
            {
                currDate = new DateTime(currDate.Year, currDate.Month, validDay);
                    result.Add(currDate);
            }
            if (currDate.Day <= validDay)
            {
                result.Add(currDate);
            }
            else
            {
                currDate = new DateTime(currDate.Year, currDate.Month, validDay);
                result.Add(currDate);
            }
        }

        return result;
    }

Sorry, I'm not quite following the problem. My understanding from your code is that you want to get dates between give dates.

Maybe you are missing else.

if (endDate.Day > validDay)
                {
                    currDate = new DateTime(currDate.Year, currDate.Month, validDay);
                    result.Add(currDate);
                }
                else
                if (currDate.Day <= validDay)
                {
                    result.Add(currDate);
                }
                else
                {
                    currDate = new DateTime(currDate.Year, currDate.Month, validDay);
                    result.Add(currDate);
                }
