MVC: Using ViewBag for Data Storage

Passing data to a View.

Sometimes a business requirement necessitates data to passed from a Controller to the View for displaying to the user.
One method MVC provides is the object ViewBag which allows you to easily attach inference-typed variables for initialing with many types of data.

To illustrate this feature, I first created a very simple controller and generic action method which constructs a message welcome users to my site along with the current date and time.
The variable “Greeting,” is a completely arbitrary name I’ve decided to use that is easy to remember later when I’m in the View.

With my Controller created, now I’ll create the View to display my welcome message.
In order to retrieve my message, all I need to do is call the ViewBag object, then its Greeting variable.

To see my example message, I’ll add a simple HTML link to my homepage which allows me to execute my controller.
