本文通过一个完整的实例，讲解如何通过访问中国天气网提供的API接口，实现天气预报功能，仅供学习分享使用，如有不足之处，还请指正。
涉及知识点
实现天气预报功能的相关知识点：
- 天气预报接口【提供风向，风速等功能】：http://www.weather.com.cn/data/sk/101120201.html
- 天气预报接口【提供天气基础功能】：http://www.weather.com.cn/data/cityinfo/101120201.html
- 新浪网的接口【其中city后的是城市的名称转码】http://php.weather.sina.com.cn/xml.php?city=%B1%B1%BE%A9&password=DJOYnieT8234jlsK&day=0
- HttpWebRequest/HttpWebResponse 访问网络的相关资源
- XmlSerializer 中序列化与反序列化功能
- Newtonsoft.Json中Json字符串的反序列化功能
- 泛型，委托
效果图
具体如图所示：
核心代码
天气代码，对接天气API接口返回的实体类，两个接口对应两个实体类：

国家代码，对应级联菜单的实体类：

新浪网天气如下图所示【数据是实时更新】：
备注：
【上面中国天气网接口读取的数据，总感觉有些不对，不知道是不是没有更新还是咋样，权当练习了】
API接口中101110101是城市的代码，如果要查询其他城市的天气，只需要修改城市的代码即可。关于城市代码，已经整理成配置文件xml，然后通过级联菜单的方式进行加载。
