asp.net – ActionLink 404错误

我有一个看起来像这样的ActionLink：

@ Html.ActionLink(“Remove”,“RemoveMenuIceCreamMapping”,“I??ceCream”,new {iceCreamId = item.IceCreamId,menuId = item.MenuId},null)

在我的IceCreamController中,我有一个看起来像这样的Action：

[HttpPost]
public PartialViewResult RemoveMenuIceCreamMapping(int iceCreamId,int menuId)
{
   ...
}

做了一点搜索并相信我可能需要修改Global.asax.cs文件的RegisterRoutes中的路由来处理这两个参数.所以我试着这样：

public static void RegisterRoutes(RoutesCollection routes)
{
   routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

   // I added this route in an attempt to handle the two parameters:
   routes.MapRoute(
      "RemoveMenuIceCreamMapping",// Route name
      "IceCream/RemoveMenuIceCreamMapping/{iceCreamId}/{menuId}",// URLwith parameters
      new
      {
         controller = "IceCream",action = "RemoveMenuIceCreamMapping",iceCreamId = UrlParameter.Optional,menuId = UrlParameter.Optional
      } 
   );

   // this was there by default
   routes.MapRoute(
      "Default","{controller}/{action}/{id}",new {controller = "Home",action = "Index",id = UrlParameter.Optional }
   };
}

但这不起作用 – 我得到了“资源无法找到”.错误,404.请求的URL：/ IceCream / RemoveMenuIceCreamMapping / 1/10

1是IceCream的Id,10是菜单的Id.

我期待发生的是将调用RemoveMenuIceCreamMapping动作,传递这两个参数,但我显然没有在这里做一些事情,可能只是误解了如何完成我想要的事情并以错误的方式去做.任何指导都将非常感激.

更新

所以,我读到的另一件事是,在阅读this SO question之后,我的ActionLink没有触发POST,因此从动作中删除[HttpPost]似乎是正确的做法.事实上,一旦我这样做,就找到了路线并执行了行动.
