ASP.NET MVC高亮显示当前页面菜单

1、创建MvcHtmlExtension扩展类

  public static class MvcHtmlExtension

     {

         public static MvcHtmlString MenuLink(this HtmlHelper helper, string text, string action, string controller)

         {

             var routeData = helper.ViewContext.RouteData.Values;

             var currentController = routeData["controller"];

             var currentAction = routeData["action"];

             if (String.Equals(action, currentAction as string, StringComparison.OrdinalIgnoreCase) &&

                 String.Equals(controller, currentController as string, StringComparison.OrdinalIgnoreCase))

             {

                 return helper.ActionLink(text, action, controller, null, new { @class = "menua" });

             }

             return helper.ActionLink(text, action, controller);

         }

     }

2、前台cshtml使用

 <div class="collapse navbar-collapse  pull-right">

                 <ul class="nav navbar-nav">

                     <li>@Html.MenuLink("育儿宝典", "YuErBaoDian", "Home")</li>

                     <li>@Html.MenuLink("关于我们", "About", "Home")</li>

                     <li>@Html.MenuLink("联系我们", "Contact", "Home")</li>

                 </ul>

 </div>
