我收到以下异常:
Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.
Source Error:
Line 34: <div>
Line 35: @Html.LabelFor(m => m.accountStatus)
Line 36: (HERE) @Html.DropDownListFor(m => m.accountStatus, Model.accStat)
Line 37: </div>
Line 38: </fieldset>
以下是我正在使用的模型。我在我的模型中创建了一个 List 属性。我在我的 Html.DropDownListFor 助手中引用它。但我得到了例外。
public class OperatorModel
{
[Required]
[Display(Name = "Account ID")]
public string accountID { get; set; }
[Required]
[Display(Name = "Account Name")]
public string accountName { get; set; }
[Required]
[Display(Name = "Password")]
public string password { get; set; }
public List<SelectListItem> accStat
{
get
{
List<SelectListItem> lst = new List<SelectListItem>();
lst.Add(new SelectListItem { Text="ACTIVE", Value="0", Selected=true });
lst.Add(new SelectListItem { Text="DEACTIVATED", Value="1" });
return lst;
}
}
编辑
以下是我的控制器代码:
public class AdministratorController : Controller
{
//
// GET: /Administrator/
public ActionResult Index()
{
return View();
}
public ActionResult Create()
{
return View();
}
public ActionResult Read()
{
return View();
}
public ActionResult Update()
{
return View();
}
public ActionResult Disable()
{
return View();
}
public ActionResult Enable()
{
return View();
}
}
