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

    ViewBag and ViewData In Asp.Net MVC.png

    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.

    Code:
    ViewData["Today"] = DateTime.Now;
    
    ViewBag uses the dynamic keyword internally and the dynamic keyword is introduced in C# v4. It allows objects to add as properties.

    Code:
    ViewBag.list = list;
    
    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.
