استفاده از JSON در MVC

send data from Controller to json

 $.ajax({

    url: '@Url.Action("GetData", "Home")',
    type: "GET",
    success: function (result) {
        $("#somediv").append(result.FirstName);
        $("#somediv").append(result.LastName);
        $("#somediv").append(result.Age);
    }
});

Consider a class like the one below

 public class User
 {
     public string FirstName { get; set; }
     public string LastName { get; set; }
 }

your action should look like this

public JsonResult GetData()  
{
   User user = new User();
   user.FirstName = "Yasser";
   user.LastName = "Shaikh";
   user.Age = 100;

   return Json(user, JsonRequestBehavior.AllowGet);
}
