Question

我正在将模型项传递到Visual Studio 2015中的字典错误中。错误消息显示：onCreateView 1 [CmsShoppingCart.Models.Data.ProductDTO]'，但是此字典需要一个模型项类型“ System.Collections.Generic.IEnumerable`1 [CmsShoppingCart.Models.ViewModels.Shop.ProductVM]”。

在Visual Studio中，我在返回View（productVMList）时收到“检测不到的代码”；我要实现的是查看产品列表和有效的产品搜索栏。我的控制器是

The model item passed into the dictionary is of type 'System.Data.Entity.Infrastructure.DbQuery

视图是

public ActionResult Category(string name,string searchString)
        {
        // Declare a list of ProductVM
        List<ProductVM> productVMList;

        using (Db db = new Db())
        {
            // Get category id
            CategoryDTO categoryDTO = db.Categories.Where(x => x.Slug == name).FirstOrDefault();
            int catId = categoryDTO.Id;

            // Init the list
            productVMList = db.Products.ToArray().Where(x => x.CategoryId == catId).Select(x => new ProductVM(x)).ToList();

            // Get category name
            var productCat = db.Products.Where(x => x.CategoryId == catId).FirstOrDefault();
            ViewBag.CategoryName = productCat.CategoryName;
        }

        var product = from c in db.Products
                      select c;
        if (!string.IsNullOrEmpty(searchString))
        {
            product = product.Where(c => c.Name == searchString);
        }
        return View(product);

        // Return view with list 
        return View(productVMList);
    }

传递到字典中的模型项的类型为'System.Data.Entity.Infrastructure.DbQuery`1
