想实现这种链接：

www.xxxx.com/news/1015.html

用这两种方法，都实现不了

Html.ActionLink()
Url.Action()

这两种方法，都会生成

/?id=1015

所以只能手动拼接链接地址了，但手动拼接的话，不能指定

new {area="xxx"}

不能指定导致，网站的路由乱了

比如，正常下请求：

www.xxxx.com/news/1015.html 正确

login.xxxx.com/news/1015.html 也能正确请求，

以下是三个路由：

 routes.MapRoute(
                name: "Default",
                url: "{controller}/{action}/{id}",
                defaults: new
                {
                    controller = "Home",
                    action = "Index",
                    id = UrlParameter.Optional
                },
                namespaces: new string[] { "NoahHotel.Extensions.Controllers.WebSite" }
                );

routes.Add("NoahHotel__Domain_Login", new DomainRoute(
                "login.noahhotel.cn",
                "{controller}/{action}/{id}",
                new
                {
                    area = "Login",
                    controller = "Home",
                    action = "Login",
                    id = UrlParameter.Optional,
                    Namespaces = new string[] { "NoahHotel.Extensions.Controllers.Login" }
                }
                ));

context.MapRoute(
                "Category",
                "Category/{Action}/{CategoryId}.html",
                new
                {
                    controller="Category",
                    action="Info",
                    CategoryId=@"(\d)+"
                },
                null,
                new string[] { "NoahHotel.Extensions.Controllers.WebSite" }
                );

是哪里出问题了吗？
