Question

 public IEnumerable<SelectListItem> GetList(int? ID)
 {
      return from s in db.List
             orderby s.Descript
             select new SelectListItem
             {
                 Text = s.Descript,
                 Value = s.ID.ToString(),
                 Selected = (s.ID == ID)
             };
 }

I return the above to a view and populate a DropDownList. I would like to add a default SelectListItem (0, "Please Select..") to the above linq result before it is returned to the view. Is this possible?

Answer 1

return new[] { new SelectListItem { Text = ... } }.Concat(
       from s in db.List
       orderby s.Descript
       select new SelectListItem
       {
           Text = s.Descript,
           Value = s.ID.ToString(),
           Selected = (s.ID == ID)
       });
