} View Code 这里只列出了一个SuperExploreIndexResult类还有CategoryResultFocusImageResultAlbumInfoResult1这三个类也做了同样的映射。这样这个接口的数据最终就可以映射为SuperExploreIndexResult类了。总之把接口中JSON数据中的对象是全部需要隐射的。 下面演示了如何调用上面的映射类。代码中所有带Decorator后缀的类都是映射类。采用了下装饰模式。 using System;

} View Code 如上只要配置好映射关系通过T4模板我们可以生成对应的映射关系类。 附上源码 下篇客户端使用了prismmef这个框架单独开发模块最后组合的方式。未完待续。。。。 转载于:https://www.cnblogs.com/nicktyui/p/4126698.html
