using System.Text;

using System.Text.Json;

using System.Xml.Serialization;

using Dadata;

using Dadata.Model;

using Microsoft.Extensions.Logging;

агента конструирую вот так

DaDataClient = new SuggestClientAsync(ApiToken, webServiceHost);

метод для вызова вот такой и четыре попытки сериализации

public async Task FindPartyAsync()

{

var result = await DaDataClient.FindParty("7707083893");

string json = JsonSerializer.Serialize(result);

MemoryStream jsonMemoryStream = new MemoryStream();

await JsonSerializer.SerializeAsync(jsonMemoryStream, result);

json= Encoding.UTF8.GetString(jsonMemoryStream.GetBuffer());

XmlSerializer _serializer = new XmlSerializer(typeof(SuggestResponse));

using (var stream2= new MemoryStream())

{

_serializer.Serialize(stream2, result);

stream2.Position = 0;

json= Encoding.UTF8.GetString(stream2.GetBuffer());

}

return json;

}

при выводе в json сериализуется в пустую строку

а на строке

XmlSerializer _serializer = new XmlSerializer(typeof(SuggestResponse));

валится вот в такую ошибку

System.InvalidOperationException : There was an error reflecting type 'Dadata.Model.SuggestResponse`1[Dadata.Model.Party]'.
