MVC Transfer ViewBag value from another controller

Question

I set the value in Viewbag.message in my HomeController by default and successfully displayed it in my Shared/_Layout.cshtml .

After that I added another TestController and in the ViewController Viewbag.message seems to be null. May I find out what is wrong with him.

Correct me if I am mistaken, from my understanding of Viewbag.message should be accessible from all corners?

Answer 1

ViewBag is a dynamic property that takes advantage of the new dynamic features in C # 4.0. This is mainly a wrapper around ViewData, and is also used to transfer data from the controller to the corresponding view.

• His life also lies only during the current request. If the redirection occurs, then its value becomes zero.
• To create complex data types, typecasting is not required.
