我正在构建一个C＃应用程序，一切似乎都是正确的，但我遇到了以下错误：

＆＃39; /＆＃39;中的服务器错误应用

无法找到资源。

请求的网址：/ Products / Main

一切似乎都是正确的。我有产品型号：

public class ProductsController : Controller
{
        // GET: Product
        public ActionResult Main(string category,
                                  string name,
                                  SortCriteria? criteria,
                                  SortOrder? order)
        {
            var model = new ProductsViewModel
            {
                Category = category,
                Name = name,
                Criteria = criteria ?? SortCriteria.Name,
                Order = order ?? SortOrder.ASC
            };

            var products = new ProductRepository().GetAll();
            model.Categories =
                products.Select(p => p.Category).Distinct().Select(c => new SelectListItem { Value = c, Text = c }).ToList();

            if (!string.IsNullOrEmpty(category))
            {
                products = products.Where(p => p.Category.Equals(category));
            }

            if (!string.IsNullOrEmpty(name))
            {
                products = products.Where(p => p.Name.ToLower().Contains(name.ToLower()));
            }

            if (criteria == SortCriteria.Name)
            {
                if (order == SortOrder.DESC)
                    products = products.OrderByDescending(p => p.Name);
                else
                    products = products.OrderBy(p => p.Name);
            }
            else
            {
                if (order == SortOrder.DESC)
                    products = products.OrderByDescending(p => p.Price);
                else
                    products = products.OrderBy(p => p.Price);
            }

            model.Products = products.Select(MapToModel).ToList();

            return View(model);
        }

        [HttpGet]
        public ActionResult Create()
        {
            return View(new ProductViewModel());
        }

        [HttpPost]
        public ActionResult Create(ProductViewModel model)
        {
            new ProductRepository().Create(MapFromModel(model));
            return RedirectToAction("Index");
        }

        private ProductViewModel MapToModel(Product p)
        {
            return new ProductViewModel
            {
                Id = p.ID,
                Name = p.Name,
                Price = p.Price,
                Category = p.Category
            };
        }

        private Product MapFromModel(ProductViewModel p)
        {
            return new Product
            {
                ID = p.Id,
                Name = p.Name,
                Price = p.Price
            };
        }
}

我有一个关于此主要操作结果的视图。

这是我的网址格式：

routes.MapRoute(
            name: "Default",
            url: "{culture}/{controller}/{action}/{id}",
            defaults: new {culture="en", controller = "Home", action = "Index", id = UrlParameter.Optional }
        );

Answer 1

输入控制器名称和操作方法名称，否则在route.config文件中更改控制器和操作方法名称...

routes.MapRoute(
            name: "Default",
            url: "{culture}/{controller}/{action}/{id}",
            defaults: new {culture="en", controller = "Products", action = "Main", id = UrlParameter.Optional }
        );

我在＆＃39; /＆＃39;中收到服务器错误应用程序在我的ASP.NET MVC 5应用程序中
