确定新的MVC。我曾问this质询时，得到一个答案，但我想知道如果有一个简单的解决方案。

说我有一个布局为一个无序列表菜单中的母版页。我怎么会去上当前选择的菜单项设置一个CSS类？

编辑：

我使用只是因为它来设置开箱当你开始一个新的MVC应用程序菜单

＆LT; UL ID =菜单＆GT;   ＆LT;立GT;＆LT;％：Html.ActionLink（家，索引，家）％GT;＆LT; /李＆GT;   ＆LT;立GT;＆LT;％：Html.ActionLink（关于，关​​于，家）％GT;＆LT; /李＆GT;＆LT; / UL＆GT;

解决方案

这的Jakub Konecki答案使我在正确的方向...这里是控制器动作我结束了：

[ChildActionOnly]    公众的ActionResult的MainMenu（）    {        VAR项目=新的List＆LT;＆菜单项GT;        {            新菜单项的{text =家，行动=索引，控制器=家，选择= FALSE}，            新菜单项的{text =我的档案，行动=索引，控制器=档案，选择= FALSE}，            新菜单项的{text =关于，行动=关于，控制器=家，选择= FALSE}        };        串动= ControllerContext.ParentActionViewContext.RouteData.Values​​ [行动]的ToString（）。        。字符串控制器= ControllerContext.ParentActionViewContext.RouteData.Values​​ [控制器]的ToString（）;        的foreach（在项目VAR项）        {            如果（item.Controller ==控制器和放大器;＆安培; item.Action ==操作）            {                item.Selected = TRUE;            }        }        返回PartialView（项目）;    }

希望这可以帮助别人。

OK new to MVC. I had asked this question earlier and got an answer but I am wondering if there is a simpler solution.

Say I have a master page with a menu laid out as an unordered list. How would I go about setting a css class on the currently selected menu item?

EDIT:

I am using the menu just as it comes setup out of the box when you start a new mvc app

<ul id="menu"> <li><%: Html.ActionLink("Home", "Index", "Home")%></li> <li><%: Html.ActionLink("About", "About", "Home")%></li> </ul>

解决方案

The answer from Jakub Konecki led me in the right direction... here is the controller action I ended up with:

[ChildActionOnly] public ActionResult MainMenu() { var items = new List<MenuItem> { new MenuItem{ Text = "Home", Action = "Index", Controller = "Home", Selected=false }, new MenuItem{ Text = "My Profile", Action = "Index", Controller = "Profile", Selected = false}, new MenuItem{ Text = "About", Action = "About", Controller = "Home", Selected = false } }; string action = ControllerContext.ParentActionViewContext.RouteData.Values["action"].ToString(); string controller = ControllerContext.ParentActionViewContext.RouteData.Values["controller"].ToString(); foreach (var item in items) { if (item.Controller == controller && item.Action == action) { item.Selected = true; } } return PartialView(items); }

Hope this helps someone.
