如何用VB.NET 可以由"questions"開始,拿取下面的資料再放入ARRAY上?

先定義 class，不過我只寫 c#

public class Question
{
public string name { get; set; }
public string email { get; set; }
public List<QuestionDetail> question_details { get; set; }
public string first_name { get; set; }
public string last_name { get; set; }
}

public class QuestionDetail
{
public string question { get; set; }
public string answer { get; set; }
public string polling_id { get; set; }
public string date_time { get; set; }
}

public class Root
{
public long id { get; set; }
public string uuid { get; set; }
public DateTime start_time { get; set; }
public List<Question> questions { get; set; }
}

You can use VB.NET to parse JSON data and extract an array of objects. Choose between Newtonsoft.Json for type safety and robustness, or System.Text.Json for a simpler approach, depending on your build now gg project needs.
