ActionResults in ASP.NET MVC

MVC implements separation of concerns and this one of the main advantages of using MVC over any other technology such as WebForms.For implementing separation of concerns MVC uses different derived classes and interfaces.For example action methods returns ActionResult.The ActionResult is a base class which has several derived classes.These classes are used for returning different types of responses from action methods.

Some of the important derived classes are:

ActionResult Name	Controller Method	Use
ViewResult	View	used for rendering a view
PartialViewResult	PartialView	used for rendering a partial view
ContentResult	Content	for returning user-defined content type such as string.
HttpNotFoundResult	HttpNotFound	Indicates the requested resource was not found.
JsonResult	Json	used for returning Json object
RedirectResult	Redirect	for redirecting to another action method using its URL
JavaScriptResult	JavaScript	for sending JavaScript content to the response.
HttpStatusCodeResult		for returning HTTP status code and description.
HttpNotFoundResult	HttpNotFound	indicates that the response was not found.

So you can use the same action method to return different ActionReturn objects.

JSON

//JSON Result example

class Employee
{
public string Name { get; set; }
public string Id { get; set; }
}

public ActionResult Index()
{
//return json object
var emp=new Employee{Id="1",Name="Emp1"};
return Json(emp);

}

Redirection

//RedirectionResult example
public ActionResult Index()
{

return Redirect(@"\seg1\seg2");

}

Content

//Content result example
public ActionResult Index()
{
return Content("test reult");
}
