  1轉為JObject

            string _Result = PostData(Appid, AppKey, imgSrc, "", "post");            JObject jsonData = JObject.Parse(_Result);            JArray jsonFace = jsonData.GetValue("face") as JArray;            if (jsonFace == null)            {                msg = "err" + "," + "格式不對";            }            else            {                int height = 0;                int width = 0;                int center_x = 0;                int center_y = 0;                string sex = "";                if (jsonFace != null && jsonFace.Count > 0)                {                    height = int.Parse(jsonFace[0]["position"]["height"].ToString());                    width = int.Parse(jsonFace[0]["position"]["width"].ToString());                    center_x = int.Parse(jsonFace[0]["position"]["center"]["x"].ToString());                    center_y = int.Parse(jsonFace[0]["position"]["center"]["y"].ToString());                    sex = jsonFace[0]["attribute"]["gender"].ToString();                }
             }

2   Dictionary

 Dictionary<string, object> objJson = JsonConvert.DeserializeObject<Dictionary<string, object>>(request);            string state = objJson["state"].ToString();
