C# 天气预报

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：

  1 using Newtonsoft.Json;
  2 using System;
  3 using System.Collections.Generic;
  4 using System.Linq;
  5 using System.Text;
  6 using System.Threading.Tasks;
  7 using System.Xml.Serialization;

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。
