More simplest way when you don't want to change your code much .. Thanks @Hugo Hilário for the concept

using Microsoft.Web.Mvc;     
using System.Web.Mvc;
using System.Web.Mvc.Html;

namespace Demo.Web.Mvc
{
    public static class UIHelper
    {             
        public static MvcHtmlString ActivePage(this HtmlHelper helper, string linkText, string action, string controller)
        { 
            string currentController = helper.ViewContext.Controller.ValueProvider.GetValue("controller").RawValue.ToString();
            string currentAction = helper.ViewContext.Controller.ValueProvider.GetValue("action").RawValue.ToString();    

            var actionLink = helper.ActionLink(linkText, action,controller);
            var isCurrentRoute = currentController == controller;// && currentAction == action; uncomment if you want to segregate by action also

            return MvcHtmlString.Create(string.Format("<li{0}>", isCurrentRoute ? " class=\"YourActiveCssClass\"" : string.Empty) + actionLink + "</li>");    

        }
    }
}

Layout page

<div class="navbar-collapse collapse">
     <ul class="nav navbar-nav"> 
          @Html.ActivePage("User", "Index", "User") 
          @Html.ActivePage("State", "Index", "State") 
          @Html.ActivePage("City", "Index", "City") 
     </ul>                     
</div>
