How do i select a day of a week for entire month at once.

I am doing something very similar but your code and as well as mine use hard coded DayofWeek.

 List<DateTime> dayList = new List<DateTime>();
        DateTime d1 = DateTime.Parse("03/01/2013");
        DateTime d2 = DateTime.Parse("04/01/2013");

        double days = (d2 - d1).TotalDays;

        for (int i = 0; i <= days; i++)
        {
            DateTime d = d1.AddDays(i);
            if ((d.DayOfWeek == DayOfWeek.Monday)) 
            {
                dayList.Add(d);
                Response.Write(d.ToString());  
            }

        }

 I want to let the user select day of the week through a DropDownList  something like 

 if ((d.DayOfWeek == DayOfWeek.DropdownList1.SelectedItem.ToString())) ;
But this wont work. Do i need to use Switch Conditions?

please initialize d1 and d2 with your ddl value, In fact I would suggest you to use Calender Extender for both the start and end date. and than on code behind get this value to the object d1 and d2.
