How to get the days for particular month and year?

Answer 1

do you mean the number of days in a month?

System.DateTime.DaysInMonth(int year, int month)

Answer 2

If you want all days as a collection of DateTime:

public static IEnumerable<DateTime> daysInMonth(int year, int month)
{
    DateTime day = new DateTime(year, month, 1);
    while (day.Month == month)
    {
        yield return day;
        day = day.AddDays(1);
    }
}

The use is:

IEnumerable<DateTime> days = daysInMonth(2010, 07);
