c# - 如何为路由注册区域

Question

我创建了具有 3 个不同区域的 MVC 应用程序。 (管理员、用户、新闻) 这是我在 App_Start 目录中的 RouteConfig.cs 文件:

public class RouteConfig
{
    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional },
            namespaces: new[] { "TestMvcApplication.Controllers" }
        );
    }
}

这是我的 AdminAreaRegisteration.cs 文件:

    namespace TestMvcApplication.Areas.Admin
{
    public class AdminAreaRegistration : AreaRegistration
    {
        public override string AreaName
        {
            get
            {
                return "Admin";
            }
        }

        public override void RegisterArea(AreaRegistrationContext context)
        {
            context.MapRoute(
                "Admin_default",
                "Admin/{controller}/{action}/{id}",
                new { controller = "Home", action = "Index", id = UrlParameter.Optional },
                namespaces: new[] { "TestMvcApplication.Areas.Admin.Controllers" }                
            );
        }
    }
}

最后这是我的 Global.asax.cs 文件内容:

namespace TestMvcApplication
{
    // Note: For instructions on enabling IIS6 or IIS7 classic mode, 
    // visit http://go.microsoft.com/?LinkId=9394801

    public class MvcApplication : System.Web.HttpApplication
    {
        protected void Application_Start()
        {
            AreaRegistration.RegisterAllAreas();

            WebApiConfig.Register(GlobalConfiguration.Configuration);
            FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
            RouteConfig.RegisterRoutes(RouteTable.Routes);
            BundleConfig.RegisterBundles(BundleTable.Bundles);
            AuthConfig.RegisterAuth();
        }
    }
}

我网站的主页已完全加载并且可以正常工作。但是管理主页或其他区域没有被路由检测到，我给出了这个错误信息:

Server Error in '/' Application.
The resource cannot be found.
Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable.  Please review the following URL and make sure that it is spelled correctly.

Requested URL: /Admin/Home

我该如何解决这个问题？ 谢谢。

Answer 1

在 RegisterRoutes 的某处调用 AreaRegistration.RegisterAllAreas()

public static void RegisterRoutes(RouteCollection routes)
{
    routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
    AreaRegistration.RegisterAllAreas();
    ....
}

提示:使用类似 RouteDebugger 2.0 的工具或 Routing Debugger调查你的路线

获取最新的 NuGet: Route Debugger for MVC或 RouteDebugger for WepApi
