Description: ViewData is a dictionary object in the ASP.NET framework that allows data to be passed from a controller to a view. This object is used to store key-value pairs, where the key is a string and the value can be any type of object. ViewData is part of the System.Web.Mvc namespace and is commonly used to send temporary data that does not need to be persisted between requests. Unlike other data transfer mechanisms, such as ViewBag or TempData, ViewData is more explicit and relies on a dictionary approach, allowing for more direct access to the data. However, its use can be less type-safe, as values are stored as objects and must be cast to the appropriate type before being used in the view. Despite this, ViewData remains a valuable tool for developers looking for a quick and flexible way to pass information to views in ASP.NET web applications.
