如何将描述附加到控制器（ASP.net MVC）中的每个 ActionMethod？
所以最近，我想出了一种动态构建导航栏菜单的方法，其中控制器（及其索引 ActionMethod）将列在每个页面顶部的水平栏中（通过 Site.Master），但也基于用户分配的角色。列出的每个控制器还将列出（在垂直下拉列表中）用户可用的 ActionMethods。
请参阅此处，了解我写给 为 ASP.NET MVC 创建一个扩展控制器类，解决了上述问题。
我意识到我还想为每个控制器自动创建一个默认索引页面，其中列出所有可用的 ActionMethod 以及每个 ActionMethod 的简短的 1 或 2 句话描述，但正在考虑如何将描述附加到 ActionMethod。
我的假设是我需要做三件事：
（1）创建我自己的属性，例如，描述并装饰每个控制器中的每个 ActionMethod，如下所示：
[Authorize(Roles="Admin")]
public class SomeController : ExtController
{
[Description("This method adjusts all of your widgets making them better.")]
public ActionResult TweakWidgets()
{
return View();
}
}
（2）创建一个 public ActionResult Index() 方法在我的基类 (ExtController) 中，继承 ExtController 的每个类都将使用该基类来显示该用户可用的 ActionMethods 及其描述的列表。
(3) 在 Views/Shared 中创建一个 Index.aspx 视图来构建这样的页面。
这是一个明智的做法吗？有更好的方法吗？
So recently, I came up with a way to dynamically build a nav-bar menu where the Controller (And its Index ActionMethod) would be listed in a horizontal bar at the top of each page (via Site.Master) but also based on the user's assigned roles. Each Controller listed would also list (in a vertical drop-down) the ActionMethods available to the user.
See here for the code I wrote to create an Extended Controller class for ASP.NET MVC which solved the above mentioned problem.
I realized that I also want to automatically create a default Index page for each Controller that lists all the ActionMethods available and a short 1 or 2 sentence description of each ActionMethod, but was pondering how to attach the description to the ActionMethod.
My assumption is that I need to do 3 things:
(1) Create my own Attribute, say, Description and decorate each ActionMethod in each Controller like so:
[Authorize(Roles="Admin")]
public class SomeController : ExtController
{
[Description("This method adjusts all of your widgets making them better.")]
public ActionResult TweakWidgets()
{
return View();
}
}
(2) Create a public ActionResult Index() method in my base class (ExtController) which will be used by every class inheriting ExtController to show a listing of the ActionMethods and their Descriptions available to that user.
(3) Create an Index.aspx View in Views/Shared that will build such a page.
Is this a sensible approach? Is there a better way to do this?

似乎是一个合理的方法。
但是，System 中已经有一个 DescriptionAttribute 类。您可能可以利用的 ComponentModel。手册页上还有一些用于反映该属性的示例代码。
Seems like a reasonable approach.
However there already is a DescriptionAttribute class in System.ComponentModel that you could probably leverage. There's some example code for reflecting on that property as well on the manual page.
