How to Pass Data From Controller to View using ViewBag and ViewData?

ViewBag and ViewData In Asp.Net MVC

Both are used to pass data from controller to view.

ViewData is a dictionary of objects which store and retrieve the data based on key.

ViewData["Today"] = DateTime.Now;

See the above code.

ViewBag uses the dynamic
keyword internally and the dynamic keyword is introduced in C# v4. It allows
objects to add as properties.

ViewBag.list = list;

See the above code.

In this, both do not provide compile-time error checking. Means if given ABC as a key name in the controller and in view if you misspell Abc then it will not provide compile-time checking. You will get the error at runtime only. It is good practice to pass data from controller to view using a strongly typed model.

ViewBag is a sugar coating over ViewData. Internally ViewBag properties are stored name-value pair list.
