在路由参数上设置多个RouteConstraint

Question

这是我正在使用的代码，但是编译器说：匿名类型不能具有相同名称的多个属性

context.MapRoute("RouteName", "statics/category/{fileName}",
                            new
                            {
                                controller = "myController",
                                action = "Index"
                            },
                            new
                            {
                                fileName = new fnRouteConstraint(),
                                fileName = new AnotherRouteConstraint()
                            });

给出约束名称：

        routes.MapRoute(
                   name: "app2",
                   url: "app/{id}",
                   defaults: new { controller = "App", action = "Index", id = UrlParameter.Optional },
                  constraints: new { RouteConstraint1 = new RouteConstraint1(),
                                     RouteConstraint2 = new RouteConstraint2() 
                                    }
               );
