Actionresult vs JSONresult

Question

I have 2 questions:

1. What is the difference between JSONResult and ActionResult?

2. When to use JSONResult in MVC?

Answer 1

According to the MSDN documentation for the ActionResult:

The ActionResult class Encapsulates the result of an action method and is used to perform a framework-level operation on behalf of the action method.

An action method responds to user input by performing work and returning an action result. An action result represents a command that the framework will perform on behalf of the action method. The ActionResult class is the base class for action results

And for JsonResult:

Represents a class that is used to send JSON-formatted content to the response.
