Question

我有以下代码：

查看：

<li>
    <a href="<%=bannerImage.Url%>">
    <img src='<%=Url.Action("GetImage", "Image", new {imageName = bannerImage.Image})%>'></a>
</li>

控制器：

public ActionResult GetImage(string imageName)
{
    var folder = ConfigurationManager.AppSettings["ImagesFolder"];
    return File(folder + imageName, "image/jpg");
}

GetImage永远不会开火哪里出错？

FireBag消息："NetworkError: 500 Internal Server Error - http://localhost:8178/error?action=GetImage&controller=Image&imageName=9bbc2035-f753-4212-985b-b6e689150529.Jpeg"

修改
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 helper调用Url.Action（“GetImage”，“Image”，new {imageName = bannerImage.Image}）使用第一个路由配置生成错误的URL。尝试添加路线（在开头）：

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

Url.Action不会调用操作
