Taken from this good article.

Create a custom extension method:

public static class HtmlExtensions
{
    public static MvcHtmlString ActionMenuItem(this HtmlHelper htmlHelper, String linkText,
        String actionName, String controllerName)
    {
        var tag = new TagBuilder("li");

        if ( htmlHelper.ViewContext.RequestContext
            .IsCurrentRoute(null, controllerName, actionName) )
        {
            tag.AddCssClass("selected");
        }

        tag.InnerHtml = htmlHelper.ActionLink(linkText, actionName, controllerName).ToString();

        return MvcHtmlString.Create(tag.ToString());
    }
}

Your HTML markup:

    

        <%= Html.ActionMenuItem("Home", "Index", "Home") %>
        <%= Html.ActionMenuItem("About", "About", "Home") %>
    

Produces the following output:

    

        
Home
