路由約束

Question

所以我有ASP.NET MVC應用程序。我想配置它的路線。以下是我的RouteConfig代碼：

public static void Register(RouteCollection routes, bool useAttributes = true) 
{ 
    routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); 
    routes.IgnoreRoute("favicon.ico");  

    routes.MapRoute(
     "Default", 
     "{controller}/{action}/{id}", 
     new { controller = "Home", action = "Index", id = UrlParameter.Optional } 
    ); 
} 

此路線工作正常。此外，我在我的應用程序中有一個區域，並嘗試配置它的路由。這是我區的註冊代碼：

public override void RegisterArea(AreaRegistrationContext context) 
{ 
    try 
    {               
     context.MapRoute(
      name: "SiteSettings_Controller", 
      url: "SiteSettings/{controller}/{action}/{id}", 
      defaults: new {action = "Index", id = UrlParameter.Optional, 
      // here I tried to use @"(UserManagement|Tools|Settings)" 
      //as constraint but it takes no effect 
      constraints: new {controller = "UserManagement|Tools|Settings" } 
     );        
    } 
    catch (Exception e) 
    { 
     // here I get InvalidOperationException "" 
    }   
} 

我想限制SiteSettingsArea的路線控制器，但是當我去爲「localhost /站點設置/ UserManagement」網址我得到消息InvalidOperationException異常「在路由表中沒有路由匹配提供的值「。我相信這個網址對應SiteSettings_Controller路線，但顯然我錯了。我怎樣才能正確限制路線中的控制器？

如果您搜索您的代碼庫SiteSettings_Controller是否出現在其他地方？

當我剛測試它時，下面的代碼肯定適用於我。

using System; 
using System.Web.Mvc; 

namespace WebApplication1.Areas.SiteSettings 
{ 
    public class SiteSettingsAreaRegistration : AreaRegistration 
    { 
     public override string AreaName 
     { 
      get 
      { 
       return "SiteSettings"; 
      } 
     } 

     public override void RegisterArea(AreaRegistrationContext context) 
     { 
      context.MapRoute(
       name: "SiteSettings_Controller", 
       url: "SiteSettings/{controller}/{action}/{id}", 
       defaults: new 
       { 
        action = "Index", 
        id = UrlParameter.Optional 
       }, 
      constraints: new { controller = "UserManagement|Tools|Settings" } 
      ); 
     } 
    } 
}
