You can't. ViewBags don't extend anything that can be passed as a parameter. I'm referring specifically to the viewbag itself, not the variable properties. You can pass those, as objects. You have other options though. You could replace the ViewBag with a session variable. Session variables can be directly accessed inside models by referencing them like this:

System.Web.HttpContext.Current.Session["error"] = "error!";

and of course you can easily reference this in an index page or controller.

Have you tried passing the Viewbag into the Method?

Where are you using the class library in your MVC project?

Update: You are calling the class library from the controller

Here is an example if your viewbag is for ice cream and your class library calculates price.

  1. In controller and viewbag is set to chocolate.
  2. Call class library and pass Viewbag.Icecream.ToString()
  3. Return from class libray "$1.50"
  4. Pass the returned data to the view
