please explain the source of JSON data, if you are talking about Web API exposing data in JSON format and you have to read it in your MVC controller then you can use HttpClient or RestClient. Refer:- https://www.sharpencode.com/article/WebApi/consuming-web-api-in-mvc-application

please at least show some JSON data , so that we could help. Another example is The example json // {"chat":[{"author":"Bob","content":"My name is Bob and I approve this message.","timestamp":1604438166}],"error":false,"message":"Chat fetched."} public class ChatMessage { public string author; public string content; public int timestamp; } public class ChatResponse { public List chat; public bool error; public string message; } ChatResponse response = JsonConvert.DeserializeObject (json); foreach (var message in response.chat) { rtbChat.AppendText($ "{message.author}: {message.content}\n" ); }
