htmlhelper dropdownlist selectlist to List<selectlist>

I create a select list and set it to viewbag then shot it as dropdownlist in view.. but it throws this exception:

{"Cannot convert type 'System.Collections.Generic.List<System.Web.Mvc.SelectListItem>' to 'System.Web.Mvc.SelectList'"}

here is my controller and html helper in view:

ViewBag.ProjeTipiList = valueSettingsService.GetRuzgarTurbunProjeTipiList().OrderBy(t => t.ProjeTipKod).ToSelectList(t => t.ProjeTipKod, t => t.Id.ToString(), "...Seçiniz...");

 @Html.DropDownListFor(model => model.ProjeTipId, (SelectList)ViewBag.ProjeTipiList, "Select One")

how can I fix this ?

Because DropDownList does not accept a list of strings, It accepts IEnumerable<SelectListItem>. 

@Html.DropDownListFor(model => model.ProjeTipId, ((List<string>)ViewBag.ProjeTipiList).Select(m => new SelectListItem { Text = m, Value = m }))

I would do it this way:

ViewBag.ProjeTipiList = valueSettingsService.GetRuzgarTurbunProjeTipiList().OrderBy(t => t.ProjeTipKod).ToList();

@Html.DropDownListFor(model => model.ProjeTipId, new SelectList(ViewBag.ProjeTipiList,"ProjeTipKod","Id", "...Seçiniz...") ,"Select One")
