Deserialize json returns null

Question

I have a problem on deserializing json. Currently, the data returns null after deserializing.

Below is the classes that I have created for binding Json.

the function for deserializing json data is in the deserialize.zip file.

What is the issue with my code? Anything wrong with my code?

There is some issue in Json data and in class structure, class location is being used as class and object name. Use the following Class structure and json: Json: { "data": [ { "tracking_number": "AQK225225", "pickup_place": "India", "delivery_place": "London", "tel_no": "+35256676452", "status": "pickup", "lastupdate_time": "2022-01-27T13:02:24.0356139+05:00", "Location": [ { "location": "MTS Pvt. Ltd", "remarks": "", "deliverydate": "12/12/2018", "pickupdate": "04/10/2018" } ] } ] } Class Structure: public class Tracking { public string Message { get; set; } public string TokenAccess { get; set; } public List data { get; set; } } public class Datum { public string tracking_number { get; set; } public string pickup_place { get; set; } public string delivery_place { get; set; } public string tel_no { get; set; } public string status { get; set; } public DateTime lastupdate_time { get; set; } public List Location { get; set; } } public class Location { public string location { get; set; } public string remarks { get; set; } public string deliverydate { get; set; } public string pickupdate { get; set; } }

Use JsonConvert and below class strucure public class Location { public string location { get; set; } public string remarks { get; set; } public string deliverydate { get; set; } public string pickupdate { get; set; } } public class Datum { public string tracking_number { get; set; } public string pickup_place { get; set; } public string delivery_place { get; set; } public string tel_no { get; set; } public string status { get; set; } public DateTime lastupdate_time { get; set; } public List Location { get; set; } } public class Root { public List data { get; set; } } Root myDeserializedClass = JsonConvert.DeserializeObject (myJsonResponse);
