mvc3之后：如果路由带上扩展名，比如这样：
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("favicon.ico");
routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); //register custom routes (plugins, etc)
var routePublisher = EngineContext.Current.Resolve<IRoutePublisher>();
routePublisher.RegisterRoutes(routes); routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}.html", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional },
new[] { "MyMvc.Web.Controllers" }
);
}
在浏览器输入： http://localhost:15526/Home/Index.html
可能会报错：404错误，
解决方法：把这玩意设置成：
<modules runAllManagedModulesForAllRequests="true">
<!-- <remove name="UrlRoutingModule-4.0" />
<add name="UrlRoutingModule-4.0" type="System.Web.Routing.UrlRoutingModule" preCondition="" />-->
</modules>
