Json数据阅读

Question

我有以下json格式数据读取问题

我尝试了这个无效的代码，因为Answer节点有一个名为数据的答案

   string filePath = Server.MapPath("../App_Data/history.txt");
          using (StreamReader r = new StreamReader(filePath))
        {
            string json = r.ReadToEnd();
            List<RootObject> Questions = 
             JsonConvert.DeserializeObject<List<RootObject>>(json);
    public class Answer
    {
    public string Answer { get; set; }
    }

    public class Question
    {
    public string Question { get; set; }
    public int CorrectAnswer { get; set; }
    public List<Answer> Answers { get; set; }
    }

    public class RootObject
    {
    public List<Question> Questions { get; set; }
    }

JSON数据：
