如何在asp.net c#中突出显示当前所选的ActionLink

@Html.ActionLink("Home", "Index", "Home")

.selected {
   font-weight: bold;
   color: red;
}

@{
    var currentController = ViewContext.RouteData.Values["controller"] as string;
    var currentAction = ViewContext.RouteData.Values["action"] as string;
}

@Html.ActionLink("Home", "Index", "Home", null, new { @class = currentController == "Home" && currentAction == "Index" ? "selected" : "" })
