Deserlizing json array into object

Question

I am struggling with converting a json array returned from httpclient into object. I have tried many things and ended up using DataContractJsonSerializer. Problem is that when I try this it gives an error 

    Message = "There was an error deserializing the object of type There are multiple root elements."

 

Code for my deserilizing is 

 

 

           

var urlPath = Url + "api/crm/gettripdata?regno="+regno;
            _httpClient.DefaultRequestHeaders.Authorization =
                     new AuthenticationHeaderValue("Bearer", accessToken);
            _httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

            HttpResponseMessage response = _httpClient.GetAsync(urlPath, HttpCompletionOption.ResponseContentRead).Result;
            apiResponse.ResponseCode = (int)response.StatusCode;

            //TripModel dataToReturnFormat = new TripModel();
            //var format = JsonConvert.SerializeObject(dataToReturnFormat);

            var data = JsonConvert.DeserializeObject(response.Content.ReadAsStringAsync().Result).ToString().TrimStart(new char[] { '[' }).TrimEnd(new char[] { ']' }); ;

            using (var ms = new MemoryStream(Encoding.Unicode.GetBytes(data)))
            {
                // Deserialization from JSON
                DataContractJsonSerializer deserializer = new DataContractJsonSerializer(typeof(List<WrapperTripModel>));
                List<WrapperTripModel> bsObj2 = (List<WrapperTripModel>)deserializer.ReadObject(ms);
            }

 And my array of json is 

 

       {\"ID\":\"139a0d0d-5b2d-4ca3-aeeb-01557ab661c1\",\"Customer\":\"79d3005a-df77-4d29-a801-df7402347c85\",\"Asset_ID\":null,\"Asset_Name\":null,\"Asset_Type\":null,\"Trip_Type\":\"active\",\"Date_Start\":\"2019-01-15T07:09:45\",\"Date_End\":\"2019-01-15T07:09:45\",\"Address\":null,\"Start_Longitude\":\"74.393348055555555555555555556\",\"Start_Address\":\"St 77 Sec K, Lahore, Pakistan\",\"End_Longitude\":\"74.394553055555555555555555556\",\"End_Address\":\"Street 10, Lahore, Pakistan\",\"Start_Latitude\":\"31.479496388888888888888888889\",\"End_Latitude\":\"31.466073055555555555555555556\",\"Maximum_Speed\":\"37\",\"Drive_Time\":\"468\",\"Idle_Time\":\"750\",\"Distance_Traveled\":\"3.05702232557921\",\"Rating_Score\":\"100\",\"Telemetry_Records\":\"48\",\"Column\":\"priority,ignition,motion_start,digital_01,output_01,power_voltage,gps_speed,gsm_cell,gsm_lac,battery_voltage,battery_current,analog_01,unknown_013,odo_diff,odometer,unknown_012,analog_03,unknown_238,unknown_014,rsq,hours_00_counter,idle_counter,\",\"ProcessedToCRM\":true,\"CreatedOn\":\"2019-01-15T07:31:51.35\",\"assetTags\":\"0000020\"},
