How to Serailize Object to Array Json C#

Hi Experts ,

Am trying to serailize a dynamic object to array . but its not working correctly and here is my code
dynamic product = new JObject();
 foreach (PropertyImage tbl in LST)
                {

                    product.FullImage = SiteUrl + "/" + tbl.Photo;
                    product.imageThumb = SiteUrl + "/" + tbl.Photo;
                    product.description = tbl.Tag;
                    product.Address = Address;
                    product.imageid = tbl.OrderNumber;
                    product.TextColor = "White";

                    if (Photos != "")
                    {
                        Photos += "," + product.ToString();
                    }
                    else
                    {
                        
                        Photos += product.ToString();
                    }
                }
                //Json += Photos;
                // Json += "]";

                var json = JsonConvert.SerializeObject(Photos, Formatting.Indented); ;

Open in new window

"{\r\n  \"FullImage\": \"http://localhost:57226/img/image1.JPG\",\r\n  \"imageThumb\": \"http://localhost

I think you should make Photos a List<product> and then pass it to the JsonConvert.SerializeObject.

Steven KribbeSoftware EngineerCommented:
Could be that there the data is already parsed by some ajax lib (jQuery) befor it is passed to JSON.parse.
karthik80cAuthor Commented:

    }).done(function (rsp) {
        debugger;
   var propertyData = JSON.parse(rsp);
