Introduction
Let us see the available action results in the controllers Asp.Net MVC 4
Controllers
Controllers are nothing but the classes that are inherited from a base class called as controller . Controller serves the web request first , so when ever a request has been made from the user (EX: To view the data ,download the file ) , controller should respond for it i.e it should send the data the UI . To send the requested data we need some entity right ? . Here in Controllers we had an entity called action result.
They are different types of action results .
ViewResult
This is the most common type of action result , that returns a view which is responsible for rendering html content to the browser
PartialViewResult
This is same as view type but it can be used in some other views also .
Redirect Result
Redirect to the user to another URL (With in the same/Different applications )
RedirectToRouteResult
Redirect the user to another action method not to the URL
ContentResult
This is used to return any type of content (i.e irrespective of datatype) .But we have to specify the content data type .By default it was string type
JsonResult
This is used to return Json Object .
JavaScriptResult
This is used when ever user wants to send the java script data object .
File Result
