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

System.DateTime.Now.Month
System.DateTime.Now.Year
System.DateTime.Now.Day

And so on.........You have lots of things you can get from DateTime.Now

Answer 3

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);

Answer 4

Hi ravi, instead of string try to declare an enum like the following

public enum Month
{
   January = 1,
   February,
   March,
   .... so on
}

then pass it to the function of yours and use the followings in your function

return System.DateTime.DaysInMonth(year, month);

Instead of string try to use integer, as it will reduce the overhead of parsing strings.
