要完成上述所需的网址，只需指定它在你的管理区域的路由配置是这样的：

To accomplish your desired URL above, just specify it in the route configuration of your "Admin" area like this:

public override void RegisterArea(AreaRegistrationContext context)
{
    context.MapRoute(
        "Admin_default",
        "Admin/Accounts/{controller}/{action}/{id}",
        new { action = "Index", id = UrlParameter.Optional }
    );
}

没有必要创建组或用户控制器。

No need to create Groups or Users controllers.
