How to pass data to layout.cshtml in shared view from home controller Index view

public ActionResult Index()
{
    var _userId = HttpContext.Session.GetString("UserCode");
    var _password= HttpContext.Session.GetString("Password");
    var results =  _userService.LoadUserMenuDetail(_userId, _password);
    return View();
}
