MVC3路由器

C# code

   public static void RegisterRoutes(RouteCollection routes)        {            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");            List<string> language = Common.XMLHelper.GetValueAll_();            foreach (string str in language)            {                routes.MapRoute(Guid.NewGuid().ToString().Substring(0, 5), "{languages}", new { controller = "Book", action = "Index", languages = str });            }            routes.MapRoute(                "Default", // 路由名称                "{controller}/{action}/{id}", // 带有参数的 URL                new { controller = "Book", action = "Index", id = UrlParameter.Optional } // 参数默认值            );        }

请教路由规则问题List<string> 是一个类似en-us、zh-cn的泛型集合,为什么我在浏览器里面输入www.123.com/zh-cnnnnnn也能进入到Action里面呢？

[解决办法]
routes.MapRoute(Guid.NewGuid().ToString().Substring(0, 5), "{languages}", new { controller = "Book", action = "Index", languages = str });
这样只是指定languages的缺省值，如果希望只允许en-us, zh-cn，用这个试试：

routes.MapRoute(Guid.NewGuid().ToString().Substring(0, 5), str , new { controller = "Book", action = "Index"});
