DropDownListFor via via ViewBag

Question

这是THIS的后续行动。

我控制器

using (ISession session = NHIbernateSession.OpenSession()) 
{ 
    var index = session.Query<Transport>().ToList(); 
    List<SelectListItem> items = new List<SelectListItem>(); 
    foreach (var car in index) 
    { 
     items.Add(new SelectListItem() 
      { Text = car.Modelis.model_name, Value = car.Modelis.Id.ToString() }); 
    } 
    ViewBag.Modeliai = new SelectList(items, "Id", "model_name"); 
    return View(items); 
} 

观是这样的：

@Html.DropDownListFor(model => model.Modelis.model_name, ViewBag.Modeliai) 

而且东西是错误的查看代码。如何将ViewBag值放到下拉列表中？

我仍然不知道你真正想要的选择，但下面应该工作：

using (ISession session = NHIbernateSession.OpenSession()) 
{ 
    var index = session.Query<Transport>().ToList(); 
    List<SelectListItem> items = new List<SelectListItem>(); 
    foreach (var car in index) 
    { 
     items.Add(new SelectListItem() 
      { Text = car.Modelis.model_name, Value = car.Modelis.Id.ToString() }); 
    } 
    ViewBag.Modeliai = items; 
    return View(index); 
} 

和

foreach (var transport in Model) 
{ 
    @Html.DropDownListFor(model => transport.Modelis.model_name, ViewBag.Modeliai) 
}
