目前我有一个包含以下字段的产品数据库表:
名称 类别(例如产品类型) 子类别(例如包装) 价
E.g类别A有3种包装。我希望它在三个不同的表中显示。我可以单独列出三张表,但表格显示相同的数据。
有人可以帮我吗?
我的公共ViewResult Index()控制器类中有这些代码。 var productsCornIndustrial =来自db.Products的cornIndustrial 其中cornIndustrial.Category ==“玉米油”& cornIndustrial.SubCategory ==“工业” 选择cornIndustrial;
return View(productsCornIndustrial.ToList());
var productsCornFoodservice = from cornFoodservice in db.Products
where cornFoodservice.Category == "Corn Oil" & cornFoodservice.SubCategory == "Foodservice"
select cornFoodservice;
return View(productsCornFoodservice.ToList());
var productsCornRetail = from cornRetail in db.Products
where cornRetail.Category == "Corn Oil" & cornRetail.SubCategory == "Retail"
select cornRetail;
return View(productsCornRetail.ToList());

了解ViewModels模式。我会这样写:
构建一个单独的ViewModel类,它将保存您的所有数据:
public class NewViewModel
{
public List<Products> IndustrialList {get;set;}
public List<Products> FoodList {get;set;}
public List<Products> RetailList{get;set;}
//ctor etc... get the data from DAL
}
...
并在控制器中使用此类将视图传递给强类型的ViewModel对象:
public ActionResult Index(int? id)
{
var items = new NewViewModel();
return View(items);
}
