Cannot apply indexing with [] to an expression of type 'System.Dynamic.DynamicObject'

Question

When I try to assign a value to the ViewBag I get the following error:

Cannot apply indexing with [] to an expression of type 'System.Dynamic.DynamicObject'

My code is as follows:

public ActionResult Success() {    ViewBag["SuccessBody"] = TempData["successBody"];    return View(); } 

PS: Why I do this you may ask? Because I am redirecting to the Success action and I needed something that persists across redirects. Then, I am assigning the value to ViewBag in order to pass the Value to a 'shared' view.

Answer 1

ViewBag is a dynamic wrapper for ViewData, so these two statements are the same:

ViewBag.SuccessBody = TempData["successBody"]; ViewData["SuccessBody"] = TempData["successBody"]; 

Answer 2

Have you tried

ViewBag.SuccessBody = TempData["successBody"];
