C# (Xamarin) 如何将 JSON 写入数组？

Question

I have output in JSON.

{
  "id": null,
  "kkt": [],
  "CallNumber": null,
  "CallDuration": null,
  "CallDurationFormat": "00:00:00",
  "CallDateTick": 0,
  "CallDate": "1970-01-01T00:00:00Z",
  "CallType": null,
  "CallDescription": "01/01/1970 12:00 a. m. -  | Duración: 00:00:00"
}

I want to write Call specification to kkt array like that:

{
  "id": null,
  "kkt": [
{

  "CallNumber": null,
  "CallDuration": null,
  "CallDurationFormat": "00:00:00",
  "CallDateTick": 0,
  "CallDate": "1970-01-01T00:00:00Z",
  "CallType": null,
  "CallDescription": "01/01/1970 12:00 a. m. -  | Duración: 00:00:00"

}
],
}

For achieve this I created class Calls that I want serialize, but I dont know how to create List<> so that the specifications are in array.

Do someone have idea how I can write List<> or do something else to achieve that Call specs will be in kkt array?

Thank you for advices!

Try to change like below:

Calls model:

public class Calls 
{

    public string id;
    public List<CallLogModel> kkt;
}

ICallLog interface:

public interface ICallLog
{
    List<CallLogModel> GetCallLogs();
}

then in your LoadCallLog() method you need to add the value that you queried into the Calls model like:

var Logg = DependencyService.Get<ICallLog>().GetCallLogs();

if (!(Preferences.ContainsKey("GUID")))
   {
       Preferences.Set("GUID", App.newUser1);
   }
 var a = Preferences.Get("GUID", "hovno"); //if this is the id of Calls model
 Calls calls = new Calls();
 calls.id = a;
 calls.kkt = Logg;
 var serialized = JsonConvert.SerializeObject(calls);
