Mentioned answer is wrong.
TempData object can be used across the controllers
Please follow below steps
public ActionResult Create(Movie movie)
@TempData["sData"] = "UserName";
return RedirectToAction("Welcome","HelloWorld");


<h2>Welcome @TempData["sData"]</h2>

The difference is once we used Tempdata not available for next use.

If you read the “TempData” and call the “Keep” method it will be persisted.


If you read “TempData” by using the “Peek” method it will persist for the next request.

TestStr = TempData.Peek("Raghav").ToString();
