I know the life cycle of ViewBag of C# MVC, is by request.

Doubt

If I set one ViewBag with the same name in several controllers, there is the possibility of the set information being read / misinterpreted in View?

Example

  • Request X access to ControllerA ago ViewBag.Mensagem = "SOP"
  • Y request access to ControllerA ago ViewBag.Mensagem = "SO"
  • Request W access to ControllerB ago ViewBag.Mensagem = "SOPortuguês"

However, the Y request is rendered first, so it occurs when using the ViewBag.Mensagem in View, turn up SOPortuguês instead of SO?

  1. One ViewBag transfers data from controller to view, ideally temporary data that is not included in a model.
  2. The life of a ViewBag lasts only during the current http request. The values of a ViewBag will be null if redirection occurs.

That is, the value of ViewBag is unique within a Request, so for each call you will have a different value in your case.
