MVC使用Newtonsoft无需实体类，实现JSON数据返回给前端页面使用

       //引用using Newtonsoft.Json; using Newtonsoft.Json.Linq;
        public ActionResult JsonSample()
        {
            ResponseResult obj = new ResponseResult();
            try
            {
                JObject jo = new JObject();
                jo.Add("UserName", "张三");
                jo.Add("Sex", "男");
                jo.Add("Age", );
                jo.Add("Money", );
                jo.Add("Address", "深圳市南山区");
                obj.info = jo;
                obj.status = true;
                obj.message = "获取信息成功";
            }
            catch (Exception ex)
            {
                obj.status = false;
                obj.message = "获取信息失败:" + ex.Message;
            }
            return Content(JsonConvert.SerializeObject(obj, Formatting.Indented));
        }
