How do I implement ViewData in ASP.NET MVC?
To implement ViewData in ASP.NET MVC, you can use the ViewData dictionary to pass data from your controller to your view.
Can you give me an example of how to use ViewData?
Sure! In your controller, you can set ViewData like this: ViewData["Message"] = "Hello, World!". Then, in your view, you can access it using @ViewData["Message"].
What are the limitations of using ViewData?
ViewData is dynamic, which means you lose compile-time checking. It's also less performant than using strongly-typed models.
When should I use ViewData instead of ViewBag?
You can use either, but ViewData is a dictionary and requires string keys, while ViewBag is a dynamic property, making it easier to use.
