C # | Create an array of data via Json Object

Recently a lot of API to access, and most will not have the code example, only the request body json format, as follows:

So we own transmission request, data is generally required JSON achieved by their dynamic code, such as requesting the following exam proofing the API , request code as follows:

  private class Body
    {
        public List<Data> data;
    }
  
  private class Data
    {
        public string id = "";
        public string item = "";
        public string analytic = "";
        public List<string> answer;
        public string materialContent = "";
        public List<string> option;
        public int subject;
    }
 
  IEnumerator Correct_Item()
    {
        Body body = new Body();

        body.data = new List<Data>();

        Data data = new Data();

        data.id = "100651";

        data.item = "下列不属于墨子思想的是()";

        data.analytic = "“克已复礼”是孔子思想";

        data.materialContent = "null";

        data.answer = new List<string>();
        data.answer.Add("D");
        
        data.option = new List<string>();
        data.option.Add("A");
        data.option.Add("B");
        data.option.Add("C");
        data.option.Add("D");

        data.subject = 1;

        body.data.Add(data);

        string requestdata = JsonMapper.ToJson(body);

        Debug.Log(requestdata);

        byte[] postBytes = Encoding.UTF8.GetBytes(requestdata);

        Dictionary<string, string> header = new Dictionary<string, string>();

        header.Add("Content-Type", "application/json");

        WWW www = new WWW("http://openapiai.xueersi.com/v1/api/nlp/nlp/correct_item?app_key=自己的app_key", postBytes,header);
        yield return www;
        if(www.isDone)
        {
            if(www.error==null)
            {
                Debug.Log(www.text);
            }
        }
    }

json request body are as follows: Request the following results:
