ViewResult V / S ActionResult

Question

How to decide whether to use ActionResult or ViewResult? I know that ActionResult is an abstract class with ViewResult as a subtype, but I have seen examples using both of these functions for the same functionality. Is there something that sets them apart?

Answer 1

ActionResultis the base type, while it ViewResultis a subtype ActionResult.

When you set the type of the returned action ActionResult, you can return any subtype of it, for example, Json, PartialView, View, RedirectToAction .

The first thing to understand --- ActionResult and ViewResult is basically a return type for a method (for example, an action in MVC).

The second difference --- ActionResult can return any type of result, if ViewResult can return the type of result View only.
