Actionresult vs JSONresult
I have 2 questions:
What is the difference between JSONResult and ActionResult?
When to use JSONResult in MVC?
ActionResult is an abstract class that an action can return.
The helper methods in Controller (eg, Json() , Content() , View() , ...) return different concrete classes that inherit ActionResult , including JsonResult .
You should declare your action methods as returning ActionResult , so that they have the freedom to return any concrete result class.
Use JsonResult when you want to return raw JSON data to be consumed by a client (javascript on a web page or a mobile client).
Use ActionResult if you want to return a view, redirect etc to be handled by a browser.
ActionResult is an abstract class . JsonResult is subtype of ActionResult . So we can return json content in both types.
