使用 MVC 使用 List<string> 填充 @Html.DropDownList

我正在嘗試使用 MVC 和 Razor 使用列表填充 @Html.DropDownList。貝婁是我的控制器程式碼。所以我需要從我的 ViewBag 中選擇列表並填寫下拉列表。

public ActionResult Register()
   {
       sparklingEntities context = new sparklingEntities();
       var query = (from discs in context.Disciplines
                    select discs).ToList();
       List<string> listOfDiscs = new List<string>();
       foreach (var item in query)
       {
           listOfDiscs.Add(item.Discipline);
       }
       ViewBag.ListOfDisciplines = listOfDiscs;
       return View();
   }

謝謝您的幫助。

如果這是在您的模型屬性的編輯器中：

@Html.DropDownList("", new SelectList(ViewBag.ListOfDisciplines, Model))

//Increase performance by Eliminating foreach loop!
public ActionResult Register()
{
   sparklingEntities context = new sparklingEntities();
   var query = (from discs in context.Disciplines
                select discs.Discipline); // change this line as discs.Discipline
   ViewBag.ListOfDisciplines = listOfDiscs;
   return View();
}
