                JavaScriptArray javascript = (JavaScriptArray)JavaScriptConvert.DeserializeObject(str);

                    JavaScriptArray json = (JavaScriptArray)obj["Other"];

                    for (int j = 0; j < json.Count; j++){
                        JavaScriptObject jsonobj = (JavaScriptObject)json[j];
                        sb.Append("Age：" + jsonobj["Age"].ToString());
                        sb.Append("Sex：" + jsonobj["Sex"].ToString());
                    }
