獲取所有區域，控制器和操作作爲樹

Question

我需要獲取已註冊爲列表和所有控制器的所有區域作爲子列表和操作的相同事物。是這樣的：

AdminArea 
    HomeController 
    Index 
    Add 
    ... 
    OtherController 
    ... 
AnotherArea 
    HomeController 
     Index 
     ... 
... 

我已經檢查的this問題的答案，而這one，但他們不是我要找的。 第一個返回所有已註冊的路由，第二個返回所有的控制器。

更新

好了，用下面的代碼，我可以得到所有的領域，並與第二個問題，我可以得到所有控制器的答案，但我不能搞清楚每個控制器屬於什麼區域。

var areaNames = RouteTable.Routes.OfType<Route>() 
      .Where(d => d.DataTokens != null && d.DataTokens.ContainsKey("area")) 
      .Select(r => r.DataTokens["area"]).ToList() 
      .Distinct().ToList(); 

Answer 1

所以這裏是我想出來的，這正是我想要的。 我希望這會有所幫助。

public virtual ActionResult Index() 
    { 
     var list = GetSubClasses<Controller>(); 

     // Get all controllers with their actions 
     var getAllcontrollers = (from item in list 
      let name = item.Name 
      where !item.Name.StartsWith("T4MVC_") // I'm using T4MVC 
      select new MyController() 
      { 
       Name = name.Replace("Controller", ""), Namespace = item.Namespace, MyActions = GetListOfAction(item) 
      }).ToList(); 

     // Now we will get all areas that has been registered in route collection 
     var getAllAreas = RouteTable.Routes.OfType<Route>() 
      .Where(d => d.DataTokens != null && d.DataTokens.ContainsKey("area")) 
      .Select(
       r => 
        new MyArea 
        { 
         Name = r.DataTokens["area"].ToString(), 
         Namespace = r.DataTokens["Namespaces"] as IList<string>, 
        }).ToList() 
      .Distinct().ToList(); 


     // Add a new area for default controllers 
     getAllAreas.Insert(0, new MyArea() 
     { 
      Name = "Main", 
      Namespace = new List<string>() 
      { 
       typeof (Web.Controllers.HomeController).Namespace 
      } 
     }); 


     foreach (var area in getAllAreas) 
     { 
      var temp = new List<MyController>(); 
      foreach (var item in area.Namespace) 
      { 
       temp.AddRange(getAllcontrollers.Where(x => x.Namespace == item).ToList()); 
      } 
      area.MyControllers = temp; 
     } 

     return View(getAllAreas); 
    } 

    private static List<Type> GetSubClasses<T>() 
    { 
     return Assembly.GetCallingAssembly().GetTypes().Where(
      type => type.IsSubclassOf(typeof(T))).ToList(); 
    } 

    private IEnumerable<MyAction> GetListOfAction(Type controller) 
    { 
     var navItems = new List<MyAction>(); 

     // Get a descriptor of this controller 
     ReflectedControllerDescriptor controllerDesc = new ReflectedControllerDescriptor(controller); 

     // Look at each action in the controller 
     foreach (ActionDescriptor action in controllerDesc.GetCanonicalActions()) 
     { 
      bool validAction = true; 
      bool isHttpPost = false; 

      // Get any attributes (filters) on the action 
      object[] attributes = action.GetCustomAttributes(false); 

      // Look at each attribute 
      foreach (object filter in attributes) 
      { 
       // Can we navigate to the action? 
       if (filter is ChildActionOnlyAttribute) 
       { 
        validAction = false; 
        break; 
       } 
       if (filter is HttpPostAttribute) 
       { 
        isHttpPost = true; 
       } 

      } 

      // Add the action to the list if it's "valid" 
      if (validAction) 
       navItems.Add(new MyAction() 
       { 
        Name = action.ActionName, 
        IsHttpPost = isHttpPost 
       }); 
     } 
     return navItems; 
    } 

    public class MyAction 
    { 
     public string Name { get; set; } 

     public bool IsHttpPost { get; set; } 
    } 

    public class MyController 
    { 
     public string Name { get; set; } 

     public string Namespace { get; set; } 

     public IEnumerable<MyAction> MyActions { get; set; } 
    } 

    public class MyArea 
    { 
     public string Name { get; set; } 

     public IEnumerable<string> Namespace { get; set; } 

     public IEnumerable<MyController> MyControllers { get; set; } 
    } 

爲了得到行動，我用這個answer。
