Deserlizing json array into object

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));
List bsObj2 = (List)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\"},

Hi Nida,

First of all you need to create class which has same property in Json object then you can use same for deserialize json strin.
