在我的项目中,有两个控制器,即家庭控制器和酒店控制器。我使用视图模型来组合两个模型类。我已经添加了我的控制器。
家庭控制器
public ActionResult Index(){
List<ImageData> details = new List<ImageData>();
var sp_details = (from s in db.service_provider
join p in db.pictures on s.SPID equals p.SPID
join c in db.cities on s.City_ID equals c.City_ID
select new { s.SPID, s.Sp_name, s.Sp_rate, s.service_type, c.Cityname, p.pic }).OrderByDescending(s => s.Sp_rate).Where(p => p.service_type == "Restaurant").Take(3).ToList();
foreach (var item in sp_details)
{
ImageData SpView = new ImageData(); // ViewModel
SpView.SPID = item.SPID;
SpView.Sp_name = item.Sp_name;
SpView.Cityname = item.Cityname;
SpView.Sp_rate = item.Sp_rate;
SpView.pic = item.pic;
details.Add(SpView);
}
return View(details);
}
酒店管制员
public ActionResult Details(int id = 0)
{
List<ImageData> details = new List<ImageData>();
var sp_details = (from s in db.service_provider
join p in db.pictures on s.SPID equals p.SPID
join c in db.cities on s.City_ID equals c.City_ID
where s.SPID == id
select new ImageData()
{
Sp_name = s.Sp_name,
Sp_location = s.Sp_location,
Cityname = c.Cityname,
service_type = s.service_type,
Sp_description = s.Sp_description,
Sp_rate = s.Sp_rate,
Sp_web = s.Sp_web,
Cnt_wh = s.Cnt_wh,
pic = p.pic
});
if (details == null)
{
return HttpNotFound();
}
return View(sp_details);
}
下面的是Index视图的一部分。我已将id值传递给Hotel Controller中的Details action方法。
<p class="name">@Html.ActionLink(item.Sp_name, "Details","Hotel", new { id = item.SPID })</p>
但是没有传递值,也没有显示酒店控制器中详细信息操作方法的详细信息。因为我是mvc 4的新手,我无法找到错误。

尝试明确添加一个代表null
参数的htmlAttributes
参数并与this overload匹配,以确保您的对象作为路由参数正确传递:
@Html.ActionLink(item.Sp_name, "Details","Hotel", new { id = item.SPID }, null)
ActionLink()
帮助程序不包含只接受您提供的Text,Action,Controller和RouteValues的重载,因此需要此额外参数。
