您可以将数据作为路线值传递：

@using (Html.BeginForm("Index", "QuestionnaireController", new { idQ = TempData["Id"] }, FormMethod.Get))
{
}

您需要定义路线：

routes.MapRoute("NameOfThisRoute",
                "QuestionnaireController/Index/{idQ}",
                 new { controller = "QuestionnaireController", action = "Index" });
