Convert LINQ Query results to List Object

You can convert the entity object to list Object by looping the LINQ Query results and adding the object to the list.

The following example code clears how to convert to List Object

public ActionResult GetChart()
        {
            List<object>chartData = new List<object>();
            chartData.Add(new object[]{
                "ShipCity", "TotalOrders"
            });

            var result = (from order in db.Orders.AsEnumerable()
                          group order by order.ShipCity into rowGroup
                          select new
                          {
                              ShipCity =rowGroup.Key,
                              TotalOrders =rowGroup.Count()
                          }).Distinct().ToList();

            foreach (var c in result)
            {
               chartData.Add(new object[]
                   {
                       c.ShipCity, c.TotalOrders 
                   });
            }
             return new JsonResult
            {
               Data = new
               {
                   success = chartData,
                   message = "Success",
               },
               JsonRequestBehavior = JsonRequestBehavior.AllowGet
            };
       }

Output:
