MVC自定义路由实现URL重写，SEO优化

    //App_Start-RouteConfig.cs
    public class RouteConfig
    {
        public static void RegisterRoutes(RouteCollection routes)
        {
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

            //商品详情自定义路由
            routes.MapRoute(
                             "Product", // 路由名称
                             "Product/{id}", // 带有参数的 URL
                             new { controller = "Default", action = "Detail", id = UrlParameter.Optional } // 参数默认值
            );

            //MVC默认自带路由
            routes.MapRoute(
                name: "Default",
                url: "{controller}/{action}/{id}",
                defaults: new { controller = "Default", action = "Index", id = UrlParameter.Optional }
            );
        }
    }

        //DefaultController  http://localhost:9900/Product/6000访问通过
        public ActionResult Detail()
        {
            int GoodID = MSCL.ConvertHelper.ObjectToInt(RouteData.Values["id"], 0);
            var model = DataRootBase.Context.From<GoodInfo>().Where(p => p.GoodID == GoodID).ToFirstDefault();
            return View(model);
        }
