浅析ASP.NET万能JSON解析器

概念介绍
还是先简单说说Json的一些例子吧。注意，以下概念是我自己定义的，可以参考.net里面的TYPE的模型设计
如果有争议，欢迎提出来探讨！

1.最简单：
{"total":0}
total就是值，值是数值，等于0

2. 复杂点
{"total":0,"data":{"377149574" : 1}}
total是值，data是对象，这个对象包含了"377149574"这个值，等于1

3. 最复杂
{"total":0,"data":{"377149574":[{"cid":"377149574"}]}}
total是值，data是对象,377149574是数组，这个数组包含了一些列的对象，例如{"cid":"377149574"}这个对象。

有了以上的概念，就可以设计出通用的json模型了。

                list.Add(builder.ToString());
            return list;
        }
    }
