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>
