自定义路由

Question

我在MembersAreaRegistration文件中的区域，称为会员及以下注册路线：

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网址：

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

随着这条路线注册一切正常。不过，我增加了以下网址：

~/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."

我也想有网址

~/Members/Profile/Edit/3 

我应该怎么才能有修改所有这些网址正常工作？

您将需要添加一些额外的路线，在您已经定义的路线之前。这是因为这些是您希望在更普通的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" } 
    );
