Asp.net mvc Action不调用Action

我有以下代码：

视图：

GetImage从不开火。 错误在哪里

FireBag消息：网络错误：500内部服务器错误-http://localhost:8178/error?action=GetImage&controller=Image&imageName=9bbc2035-f753-4212-985b-b6e689150529.Jpeg

编辑： 我的路线：

routes.MapPageRoute("Error", "error", "~/Error.aspx");

            routes.MapRoute(
                "Cinema Full", // Route name
                "{city}/cinema/{id}/{action}/{subaction}", // URL with parameters
                new { city = "astana", controller = "Cinema", action = "Overview", subaction = UrlParameter.Optional }, // Parameter defaults
                new { city = new CityConstraint() }
            );

            routes.MapRoute(
                "Cinema", // Route name
                "{city}/cinema", // URL with parameters
                new { city = "astana", controller = "Cinema", action = "Index" }, // Parameter defaults
                new { city = new CityConstraint() }
            );

            routes.MapRoute(
                "Default", // Route name
                "{controller}/{action}/{subaction}", // URL with parameters
                new { controller = "Home", action = "Index", subaction = UrlParameter.Optional } // Parameter defaults
            );

我认为url帮助程序调用url.ActionGetImage，Image，new{imageName=bannerImage.Image}会使用第一个路由配置生成错误的url。尝试在开始处添加路由：

    routes.MapRoute(
        "ImageGen", // Route name
        "images/{imageName}", // URL with parameters
        new { controller = "Image", action = "GetImage"} // Parameter defaults
    );

您在global.asax中的路由配置是什么？您还需要显示CityConstraint类的代码。

routes.MapPageRoute("Error", "error", "~/Error.aspx");

            routes.MapRoute(
                "Cinema Full", // Route name
                "{city}/cinema/{id}/{action}/{subaction}", // URL with parameters
                new { city = "astana", controller = "Cinema", action = "Overview", subaction = UrlParameter.Optional }, // Parameter defaults
                new { city = new CityConstraint() }
            );

            routes.MapRoute(
                "Cinema", // Route name
                "{city}/cinema", // URL with parameters
                new { city = "astana", controller = "Cinema", action = "Index" }, // Parameter defaults
                new { city = new CityConstraint() }
            );

            routes.MapRoute(
                "Default", // Route name
                "{controller}/{action}/{subaction}", // URL with parameters
                new { controller = "Home", action = "Index", subaction = UrlParameter.Optional } // Parameter defaults
            );

    routes.MapRoute(
        "ImageGen", // Route name
        "images/{imageName}", // URL with parameters
        new { controller = "Image", action = "GetImage"} // Parameter defaults
    );
