'Tempdata' does not exist in current context

Question

I am trying to pass some value from one controller to another something like

TempData["data"]="data";

but it says Tempdata does not exist in current context.So i decided to use ViewBag and surprisingly, i get the same error message for ViewBag.

I read about it and it has something to do with BaseController.So I really have to derive from a basecontroller to make it work?

Your controller must be inheriting `System.Web.Mvc.Controller` — Tushar Gupta, Feb 03 '16 at 07:12
Your controller must be derived from Controller not ControllerBase!!! — Lungisani, Jan 29 '20 at 11:35

Your controller must be derived from BaseController
You can use TempData[""] to pass message from one controller to another. Here is a code which will help you:

namespace namespaceName.Controllers
{
    public class ControllerName : Controller
    {
        public ActionResult firstController()
        {
            var data = TempData["data"].ToString();
        }
        public ActionResult secondController()
        {
            TempData["data"] = "data";
            return RedirectToAction("firstController");
        }
    }
}

the TempData["data"] = "data" will be passed to firstController from secondController
Hope this helps
