What is Action Method in ASP.NET MVC 5?

All the public methods which are written inside a Controller are known as Action Method. When creating Action Method you must follow these rules.

a. Action method must be public.
b. It cannot be overloaded.
c. It cannot be a static method.
d. Every controller has at least one default Action method Index() that returns the view page.
e. ActionResult is a base class of all the result type action methods.

Types of Action Method

Action Result

ActionResult is the base class of all the result type action method. There are following Result type action method in MVC.

ViewResult - Represents HTML and markup.
EmptyResult - Represents no result.
RedirectResult - Represents a redirection to a new URL.
JsonResult - Represents a JavaScript Object Notation result that can be used in an AJAX application.
JavaScriptResult - Represents a JavaScript script.
ContentResult - Represents a text result.
FileContentResult - Represents a downloadable file (with the binary content).
FilePathResult - Represents a downloadable file (with a path).
FileStreamResult - Represents a downloadable file (with a file stream).

Programming Example

1. ViewResult
// GET: Item
        public ViewResult Index()
            ViewBag.ItemList = "Computer Shop Item List Page";
            return View();
Output: It will return Index View Page
//GET: Item
        public EmptyResult Index()
            ViewBag.ItemList = "Computer Shop Item List Page";
            return new EmptyResult();
Output: It will return a blank page with no result.
Redirect Results is used for returning results to specific url. When you need to redirect to another action method, you can use RedirectResult Action Method.
public RedirectResult Index()
            return Redirect("Home/Contact");

When you will run this code, It will redirect you to Contact Page.
JSON Result returns simple text file format and key value pairs. Sometimes you may want to return data in JSON Format and that situation you JSONResult is the best option.
public JsonResult Index()
            Employee emp = new Employee()
                ID = "Emp23",
                Name = "Steven Clark",
                Mobile = "825415426"                
            return Json(emp, JsonRequestBehavior.AllowGet);
        public class Employee
            public string ID { get; set; }
            public string Name { get; set; }
            public string Mobile { get; set; }
