  • JSON的部分序列化

    http://hi.baidu.com/%B1%F9%D1%A9%D2%F8%C1%AB/blog/item/39a1c4fb0ae8ebccb58f31e0.html#0

    通常当用到大的Json文档的时候,你可能只对其中的一小个片段信息感兴趣。这种情况下你想把Json.Net转换为.Net 对象就会让人很困扰,因为你必须为Json的整个结果定义一个.Net的类。

    使用Json.Net很容易避开这个问题。在把它们传递到Json.Net序列化器之前,你可以使用Linq to Json 提取Json中你想要序列化的一些片段。

     string googleSearchText = @"{
