Как отсортировать две строки Json разных типов? ⇐ C#

[Anonymous]

Please tell me how to check which json was received. The VK API server sends a normal response:

{ "ts": "209", "updates": [{ "event_id": "0237692ceafd3e", "group_id": 00000001, "object": { "client_info": { "button_actions": ["text", "vkpay", "open_app", "location", "open_link", "callback", "intent_subscribe", "intent_unsubscribe"], "carousel": true, "inline_keyboard": true, "keyboard": true, "lang_id": 0 }, "message": { "attachments": [], "conversation_message_id": 106, "date": 1709378417, "from_id": 00000001, "fwd_messages": [], "id": 151, "important": false, "is_hidden": false, "out": 0, "peer_id": 00000001, "random_id": 0, "text": "Привет", "version": 10000268 } }, "type": "message_new", "v": "5.199" } ] } And Json with an error:

{ "failed": 1, "ts": 30 } In this class, I have to skip the normal Json response and leave the Json with an error.

using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Text.Json; using System.Threading.Tasks; namespace Brusketta.src.VKModels.Json { internal class FailedJson { public int Response(string jsonString) { var response = 0; Filed? filed = JsonSerializer.Deserialize(jsonString); if (filed?.failed != 0) { response = filed.failed; } return response; } } public class Filed { public int failed { get; set; } public int ts { get; set; } } } When a Json response with an error arrives, everything works fine, but when a normal response arrives, I get an exception: The JSON value could not be converted to System.Int32. Cannot get the value of a token type string as a number. Debugging shows an exception in the line

Filed? filed = JsonSerializer.Deserialize(jsonString); Maybe there is an elegant solution to my problem in C#?

Thanks.

Sort the Json objects, get their length and compare them. Check for null.
