Question

I have no idea how to work this out but my drop down list code looks as follows:

in the action:

  DateTime[] allSundaysInMonth = GetDatesOfSundays(System.DateTime.Now);
  DateTime[] allSundaysInLastMonth = GetDatesOfSundays(System.DateTime.Now.AddDays(-30)); 
  List<SelectListItem> listOfSundays = new List<SelectListItem>();
  foreach (DateTime dt in allSundaysInThisMonth)
  {
    listOfSundays.Add(new SelectListItem
    {
      Text = dt.Name,
      Value = dt.Id.ToString(),
      Selected = dt.CompanyId == Id
    });

    return listOfSundays;
  }

I need to take the last two sundays af last month and all sundays of this month, but not future sundays, and build a list with all these sundays.

Answer 1

This is something i did while on a past project

public List<SelectListItem> CompanySelectList(List<Company> companyList, int selectedId = 0)
    {
        List<SelectListItem> listToReturn = new List<SelectListItem>();
        foreach (Company c in companyList)
        {
            listToReturn.Add(new SelectListItem
            {
                Text = c.CompanyName,
                Value = c.CompanyId.ToString(),
                Selected = c.CompanyId == selectedId
            });
        }
        return listToReturn;
    }

just modify your T so it will return what you need.
