.Net解析JSON字符串

        string json = "{\"Name\":\"防盗锁\",\"CateIds\":\"438,441,447\",\"Brand\":\"kkk\",\"ItemNO\":\"\",\"MarketPrice\":\"200\",\"MinPrice\":\"\",\"MaxPrice\":\"\",\"Description\":\"防盗锁士大夫\"}";
               

使用方法：
dynamic dy = App_Code.JsonParser.FromJson(json);
string stName = dy.Name;
