Solution 1

Let .Net handle this for you:

public DateTime LastDayOfMonthFromDateTime(DateTime dateTime)
{
   DateTime firstDayOfTheMonth = new DateTime(dateTime.Year, dateTime.Month, 1);
   return firstDayOfTheMonth.AddMonths(1).AddDays(-1);
}

Solution 2

C#

public int GetDaysInMonth(int month, int year)
{
DateTime date = DateTime.Now;
if (month == 12) date = new DateTime(year + 1, 1, 1);
else date = new DateTime(year, month + 1, 1);
return date.AddDays(-1).Day;
}

Thanks Mohd Wasif and Sunasara Imdadhusen for your immediate response.

I will explain my application briefly.(ASP.NET)
I place 3 DropDownLists in my design page.

DDL1-Date (1-31)
DDL2-Month (Jan-Dec)
DDL3-Year (2000-2015)
eg: When i select 2001,Mar...My date must show 31.
When i select 2004,Feb...My date must show 29.
Kindly help me.

Thanks & Regards,
Sukanya Narayanan.

protected void SelectLastDateByMonthAndYear()
{
/// Convert the month & year values to int before passing them to GetDaysInMonth
int days = GetDaysInMonth(<selected value from month drop down>, <selected value from year drop down>);

ddlDate.Items.FindByText(days.ToString()).Selected = true;
}
