URL 授权的 Mvc Areas-Controller-Action 列表

Question

它可以是不同的方法。结果，我想从应用程序中获取所有 url。

我计划在我的应用程序中授权。而且，我需要这些（区域名称、控制器名称、操作名称）来询问何时发出请求。简而言之，URL 地址。我试过这些。

Example:

• Trial (AreaRegistration)
  • Trial1Controller
    • Home ActionResult    >>> /Trial/Trial1/Home/
    • A ActionResult           >>> /Trial/Trial1/A/
    • B ActionResult           >>> /Trial/Trial1/B/
  • Trial2Controller
• Examp (AreaRegistration)
  • Examp1Controller
    • Home ActionResult    >>> /Examp/Examp1/Home/
    • A ActionResult;          >>> /Examp/Examp1/A/
  • Examp2Controller
    • Home ActionResult    >>> /Examp/Examp2/Home/

var areas = Assembly.GetExecutingAssembly().GetTypes().Where(type => typeof(AreaRegistration).IsAssignableFrom(type)).ToList();
foreach(var area in areas)
{
    var controllers = Assembly.GetExecutingAssembly().GetTypes().Where(type => typeof(Controller).IsAssignableFrom(type)).ToList();
    foreach (var controller in controllers)
    {
         var methods = controller.GetMethods(BindingFlags.Public | BindingFlags.Instance);
         foreach (var method in methods)
         {
              if (method.ReturnType == typeof(ActionResult))
              {
                    lstControllerActions.Add(string.Format("Area -> Controller -> Action : {0} -> {1} -> {2}", area.Name, controller.Name, method.Name));
              }
         }
     }
}

lstControllerActions Result:

• Area -> Controller -> Action : Trial -> Trial1 -> Home
• Area -> Controller -> Action : Trial -> Trial1 -> A
• Area -> Controller -> Action : Trial -> Trial1 -> B
• Area -> Controller -> Action : Trial -> Examp1 -> Home
• Area -> Controller -> Action : Trial -> Examp1 -> A
• Area -> Controller -> Action : Trial -> Examp2 -> Home
• Area -> Controller -> Action : Examp-> Trial1 -> Home
• Area -> Controller -> Action : Trial -> Trial1 -> A
• Area -> Controller -> Action : Trial -> Trial1 -> B
• Area -> Controller -> Action : Trial -> Examp1 -> Home
• Area -> Controller -> Action : Trial -> Examp1 -> A
• Area -> Controller -> Action : Trial -> Examp2 -> Home

一切都很美好，但是，区域之间没有连接控制器。

这个问题已经解决了。来自 @kamal-hamidi 的引述，谢谢。

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

    // Get all controllers with their actions
    var getAllcontrollers = (from item in list
        let name = item.Name

        {
            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(
