在视图中显示从控制器的列表MVC

Question

enter image description here我有一个控制器，从用户定义的函数使用实体framwework.I我试图只显示我的数据在视图中，并填充我的表中的数据。

我的控制器看起来是这样的：

public ActionResult Index() 
    { 
     var description = "Toyota"; 
     QuotingEngineEntities1 vehicles = new QuotingEngineEntities1(); 


     List<object> list = new List<object>(); 

     using (var context = new QuotingEngineEntities1()) 
     { 

      var vehicle = from s in context.fn_GetVehicle(description) 
          select new 
          { 
           s.MAKE, 
           s.MODEL, 
           s.PRICE, 
           s.POWER, 
           s.Transmission 
          }; 


      list.Add(vehicle.FirstOrDefault()); 


     } 

     ViewBag.list = list; 

     return View(ViewBag.list); 
    } 

和我的看法是这样的

@foreach (var v in ViewBag.list) 
    { 
     <li>@v.MODEL</li> //i get an error 
     <br /> 
    } 

我终于得到它的干活。通过数据不得不循环将其添加到列表中。

public ActionResult Index() 
     { 
      var description = "Toyota"; 

      List<fn_GetVehicle_Result> list = new List<fn_GetVehicle_Result>(); 

       using (var context = new QuotingEngineEntities1()) 
       { 

        var query = context.fn_GetVehicle(description); 

        foreach (var v in query) 
        { 

         list.Add(v); 

        } 

        ViewBag.list = list; 
       } 



      return View("Index",ViewBag.list); 
     }

您正在尝试使用Viewbag与您的清单数据，但它不这样做明智的方式，你不要有Viewbag加入到View()方法。它由控制器自动发送到视图中。

我建议使用ViewModel或ExpandoObject将您的集合发送到视图中。你可以实现诸如以下

//控制器

public ActionResult Index() 
{ 

     using (var context = new QuotingEngineEntities1()) 
     { 

      var vehicle = from s in context.fn_GetVehicle(description) 
          select new 
          { 
           s.MAKE, 
           s.MODEL, 
           s.PRICE, 
           s.POWER, 
           s.Transmission 
          }; 

      dynamic yourmodel = new ExpandoObject(); 
      yourmodel.Vehicles = vehicle.ToList(); 

     } 


     return View(yourmodel); 
} 

//视图

@using YourProject; // Your Project Name 
@model dynamic 

@foreach (var v in model.Vehicles) 
{ 
    <li>@v.MODEL</li> 
    <br /> 
}
