How to add “active” class to Html.ActionLink in ASP.NET MVC

I'm trying to add an"active" class to my bootstrap navbar in MVC, but the following doesn't show the active class when written like this:

<ul class="nav navbar-nav">

  <li>@Html.ActionLink("Home", "Index", "Home", null, new {@class="active"})</li>

  <li>@Html.ActionLink("About", "About", "Home")</li>

  <li>@Html.ActionLink("Contact", "Contact", "Home")</li>

</ul>

This resolves to what looks like a correctly formatted class, but doesn't work:

<a class="active" href="/">Home</a>

In the Bootstrap documentation it states that 'a' tags shouldn't be used in the navbar, but the above is how I believe is the correct way of adding a class to an Html.ActionLink. Is there another (tidy) way I can do this?

Extension:

public static MvcHtmlString LiActionLink(this HtmlHelper html, string text, string action, string controller)

{

    var context = html.ViewContext;

    if (context.Controller.ControllerContext.IsChildAction)

        context = html.ViewContext.ParentActionViewContext;

    var routeValues = context.RouteData.Values;

    var currentAction = routeValues["action"].ToString();

    var currentController = routeValues["controller"].ToString();



    var str = String.Format("<li role=\"presentation\"{0}>{1}</li>",

        currentAction.Equals(action, StringComparison.InvariantCulture) &&

        currentController.Equals(controller, StringComparison.InvariantCulture) ?

        " class=\"active\"" :

        String.Empty, html.ActionLink(text, action, controller).ToHtmlString()

    );

    return new MvcHtmlString(str);

}

Usage:

<ul class="nav navbar-nav">

    @Html.LiActionLink("About", "About", "Home")

    @Html.LiActionLink("Contact", "Contact", "Home")

</ul>

In layout page
