在Html.RenderAction MVC路线图得到了例外：在路由表中没有路由提供的值相匹配

我使用ASP.NET MVC 5，这是我的路线图所有的动作，除了：

I use ASP.NET MVC 5 and this is My Route Map for all of the actions except Home/index:

 routes.MapRoute(
                name: "randomNumber",
                url: "{controller}/{randomNumber}/{action}",
                defaults: new { },
                constraints: new { randomNumber = @"\d+" }
            );

和第一页：我不想用 {randomNumber}

因此​​，第一个解决方案，我认为是：

So the first solution I think is:

routes.MapRoute(
                 name: "Default",
                 url: "{controller}/{action}",
                 defaults: new { controller = "Home", action = "Index" }
            );

该路线图解决我的问题，但造成的另一个问题是：客户端可以访问其他操作，而不 {randomNumber} ，但我只是想在首页 首页控制器不随机数进行访问。

This route map solve my problem, but caused another problem that is: clients can access to other actions without {randomNumber}, but I just want the Index action of Home Controller accessed without random number.

其他的解决办法是：

  routes.MapRoute(
                     name: "Default",
                     url: "Home/Index",
                     defaults: new { controller = "Home", action = "Index" }
                );

但有了这个地图我无法访问与根URL，我需要访问与根URL是这样的： www.mydomainaddress.com

But with this map I can't access Home/index with root url, I need to access Home/index with root url like this: www.mydomainaddress.com

最后，我发现这一点：

   routes.MapRoute(
                     name: "Default",
                     url: "",
                     defaults: new { controller = "Home", action = "Index" }
                );

但我得到的例外：在 index.cshtml 在路由表中没有路由匹配所提供的值文件中的这一行： @ {Html.RenderAction（archiveList中，家）;}

我不知道的路线图，我添加的关系Cyclobutyl和的RenderAction 帮手？

I don't know the ralation of the route map that I added and RenderAction helper?

不过，如果我添加下面的两个路线图都，一切都会好的：

But If I add both the following two route maps, everything will be OK:

   routes.MapRoute(
                     name: "Default",
                     url: "",
                     defaults: new { controller = "Home", action = "Index" }
                );

 routes.MapRoute(
               name: "HomeActions",
               url: "Home/{action}",
               defaults: new { controller = "Home" }
           );

但你也知道（我需要用随机数访问的所有动作），我不能添加第二个地图路线

But I can't add the second map route as you know (I need all actions accessed with random number)

我不明白发生了什么事，当我添加默认地图，什么相关的的RenderAction 帮手？

I can't understand what happened when I add the Default map, and what related to RenderAction helper?

任何人不会对此有什么想法？任何建议？

Does any one have any idea about this? any suggestion?
