ASP.NET MVC 区域 return 空白视图

Question

我有一个 ASP.NET MVC 应用程序，其中也有区域。

简而言之 url 我在如下区域的 RouteConfig 中设置了短 urls 的所有 actionmethods 路由。

//admin dashboard having short url admin/dashboard
context.MapRoute(
            "admin_dashboard",
            "admin/dashboard",
            new { area = "admin", controller = "admin", action = "dashboard" }
        );

//student list having short url admin/studentlist
        context.MapRoute(
            "student_list",
            "admin/studentlist",
            new { area = "admin", controller = "students", action = "List" }
        );

//new student having short url admin/student/new
        context.MapRoute(
            "student_new",
            "admin/student/new",
            new { area = "admin", controller = "students", action = "RegisterStudent" }
        );

//edit student having short url admin/student/id
        context.MapRoute(
            "student_edit",
            "admin/student/{id}",
            new { area = "admin", controller = "students", action = "RegisterStudent" }
        );

如您所见，我已经为所有操作方法定义了短 urls，它也工作正常，除了最后两个调用该方法但 returns 空白视图。

        [Route("admin/student/{id}")]
        [Route("admin/student/new")]
        public ActionResult RegisterStudent(string Id)
        {
         ....mycode
         return View("RegisterStudent", mymodel);
        }

问题是调用方法没有任何错误，但没有返回视图。它 returns 空白视图。为什么会这样是不是我做错了？

Answer 1

路由中id默认为整数。您正在将其视为字符串。

Answer 2

如果你的请求是去你的action方法，那么路由是没有问题的。如果您的操作返回空白 View 那么，一定是 View 本身有问题。
