DropDownListFor通过ViewBag

Question

这是THIS的后续行动.

我的控制器

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);
}

视图是这样的：

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

视图代码有问题。如何将ViewBag值放到下拉列表中？

我仍然不确定你到底想要选择什么，但以下几点应该有效：

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)
}
