如要实现列表中地址全路径“bubufx-11-2.html”，在首次进入时，使用短路径“bubufx.html”，只有再次href后才显示全路径“bubufx-11-2.html”，下面使用路由规则来实现。

​

//"/bubufx-11-2.html"，eID=11，pageIndex=2
routes.MapRoute("bubufx", "{action}-{eID}-{pageIndex}.html",
               new { controller = "bubufx", action = "Index" });

//"/bubufx-11.html"，eID=11，pageIndex默认是1
routes.MapRoute("bubufx_No_pageIndex", "{action}-{eID}.html",
               new { controller = "bubufx", action = "Index", eID = 1, pageIndex = 1 });

//"/bubufx.html"，eID默认是1，pageIndex默认是1
routes.MapRoute("bubufx_No_eID_pageIndex", "{action}.html",
               new { controller = "bubufx", action = "Index", eID = 1, pageIndex = 1 });

完整方案：

routes.MapRoute("bubufx_wuAction", "{controller}.html", new { controller = "home", action = "index", id = "" });//没有Action的路由规则
routes.MapRoute("bubufx_wuID", "{controller}/{action}.html", new { controller = "home", action = "index", id = "" });//没有ID的路由规则
routes.MapRoute("Default", "{controller}/{action}/{id}.html", new { controller = "home", action = "index", id = "" });//默认匹配
routes.MapRoute("Root", "", new { controller = "home", action = "index", id = "" });//根目录路由规则
