           emp.salary = "500000";
           emp.position = "Team Lead";
           emp.start_date = "01/01/2016";
           emp.office = "BUPA";
           emp.extn = 4156;
           emplist.Add(emp);
      var json = JsonConvert.SerializeObject(emplist);
       return Json(json.ToArray(), JsonRequestBehavior.AllowGet);
     }

$(document).ready(function () {
        debugger;
        var urllink = "/Home/GetData";
        var table = $('#example').DataTable({            
            ajax: {
                url: urllink,
                
            },
            "columns": [
                {
                    "className": 'details-control',
                    "orderable": false,
                    "data": null,
                    "defaultContent": ''
                },

            ],

Solution 1

The Json helper method[^] expects the object you want to return, not an already-serialized JSON string.

Remove the call to JsonConvert.SerializeObject, and just pass in the list:

C#

public JsonResult GetData()
{
    List<Employee> emplist = new List<Employee>();
    
    ...
    
    return Json(emplist, JsonRequestBehavior.AllowGet);
}
