asp.net-mvc-2 - 区域内的自定义路由

Question

我有一个名为 Members 的区域，并在 MembersAreaRegistration 文件中注册了以下路线:

context.MapRoute(
     "Members_Profile",
     "Members/Profile/{id}",
     new { controller = "Profile", action = "Index", id = UrlParameter.Optional },
     new string[] { "MyProject.Web.Mvc.Areas.Members.Controllers" }
     );

context.MapRoute(
     "Members_default",
     "Members/{controller}/{action}/{id}",
     new { controller = "Home", action = "Index", id = UrlParameter.Optional },
     new string[] { "MyProject.Web.Mvc.Areas.Members.Controllers" }
     );

我希望能够映射以下 URL:

~/Members (should map ~/Members/Home/Index )
~/Members/Profile/3 (should map ~/Members/Profile/Index/3)

通过此路由注册，一切正常。不过，我添加了以下 URL:

~/Members/Profile/Add 

我得到了错误:

"The parameters dictionary contains a null entry for parameter 'id' of non-nullable type 'System.Int32' for method 'System.Web.Mvc.ActionResult Index(Int32)' in 'MyProject.Web.Mvc.Areas.Members.Controllers.ProfileController'. An optional parameter must be a reference type, a nullable type, or be declared as an optional parameter."

我也想要网址

~/Members/Profile/Edit/3

为了让所有这些 URL 正常工作，我应该修改什么？

您需要在已定义的路由之前添加一些额外的路由。这是因为这些是您希望在已有的更通用路线之前选择的特定路线。

context.MapRoute(
     "Members_Profile",
     "Members/Profile/Add",
     new { controller = "Profile", action = "Add" },
     new string[] { "MyProject.Web.Mvc.Areas.Members.Controllers" }
     );

context.MapRoute(
     "Members_Profile",
     "Members/Profile/Edit/{Id}",
     new { controller = "Profile", action = "Edit", id = UrlParameter.Optional },
     new string[] { "MyProject.Web.Mvc.Areas.Members.Controllers" }
     );
