Get all the ActionResult as JsonResult only in mvc

Dileep Singh

So i have a scenario where i need to impliment like .. i have some controllers classes inside there are some "Action Method" ... and i want to allow only the JsonResult as a return type for all the action methods present in the all Controllers. but here i don't want to go on each action method in each controller and write JsonResult as return type... we don't want to allow other types of ReturnType (only JsonResult should Allow):..How we can do that.. dose anyone have solution for this..

Hi Dileep,

You no need to change your method return type ActionResult but you need to change you result return type as json. once you are getting result from database then you need to send response as json.

suppose i have a controller and inside i have the two action method..
public class HomeController : Controller
{
    [HttpGet]
    public ActionResult Index()
    {
        var test=new{};
        return Json(test,JsonRequestBehavior.AllowGet);
    }
    [HttpPost]
    public ActionResult GetAnswer(string question)
    {
        //statement 1
        //statement 1
        var answer=new {};
        return Json(answer, JsonRequestBehavior.AllowGet);
    }
}
And since i have written the return type as "ActionResult" so from the action method we can return view, json, file, javvascript ete.. but here what i need only json are return type.. and to achive this ..i don't want to mention the "JsonResult" on each action methods ...Like
[HttpGet]
public JsonResult Index() // don't want to specify explicitly on each action method to get only Json Result
{
    var test=new{};
    return Json(test,JsonRequestBehavior.AllowGet);
}
[HttpPost]
public JsonResult GetAnswer(string question)
{
    //statement 1
    //statement 1
    var answer=new {};
    return Json(answer, JsonRequestBehavior.AllowGet);
}
so is there any way by using that we can allow only json result for whole application.

hi
I could not clear ,But that much I understood
The method access specifier should private and return type jsonresult
Example
private JsonResult Getata()
{
var o = "test";
return Json(o, JsonRequestBehavior.AllowGet);
}
