Redirect user based on Role using Custom Authorization Filter in ASP.Net MVC

I have applied authorization filter with role id on each action method in a controller.

For exmaple I have 3 action method in a controller

how to redirect user based on role in mvc c#

    public class userValidationController : Controller
    {
        private ResourceEntities db = new ResourceEntities();
        private ResourceEntities2 userRoleDb = new ResourceEntities2();
        [HttpPost]
        public ActionResult ValidateUser(string user, string pass)
        {
            ResourceEntities1 ValidateUser = new ResourceEntities1();
            var s = ValidateUser.sp_Validation(user, pass);
            var item = s.FirstOrDefault();
            if (item == 1)
            {
                ViewBag.Message = "Invalid deleated user";
                return View("Index");
            }
            else if (item == 2)
            {
                Session["UserName"] = user;
                return RedirectToAction("Index", "userRole");
            }
            else if (item == 3)
            {
                ModelState.AddModelError("", "Invalid User Name or Password");
                ViewBag.Message = "Invalid user kindly contact admin";
                return View("Index");
            }
            else
            {
                ModelState.AddModelError("", "Invalid User Name or Password");
                ViewBag.Message = "Invalid user kindly contact admin";
                return View("Index");
            }
        }
    }

when Item == 2 I am redirect to userRole Controller where I want request to select action method automatically based on role ID.

Please suggest how can I do it.

[CustomAuthFilter]
public class userRoleController : Controller
{
    [CustomAuthorizeAttribute(0)]
    public ActionResult Index()
    {
        return View();
    }

    [CustomAuthorizeAttribute(1)]
    public ActionResult candidateRole()
    {
        return View();
    }

    [CustomAuthorizeAttribute(2)]
    public ActionResult hrRole()
    {
        return View();
    }
}
