C#制作实用天气闹钟

只要花上一个小时，就可以用C#语言给心爱的TA定制一个WinForm天气闹钟，加上自己录制的闹铃，美哉美哉！天气数据来源于Web Service 接口（http://ws.webxml.com.cn/WebServices/WeatherWS.asmx）。

 

最终效果

 

操作步骤

1. 文件 --> 新建 --> 项目 -->Visual C# --> Windows 窗体应用程序

 

2. 在项目中的引用上点击鼠标右键，选择添加服务引用 --> 高级--> 添加 Web 引用

 

3. 在URL中填写天气Web Service：http://ws.webxml.com.cn/WebServices/WeatherWS.asmx，并点击右边的“前往”小图标，自动生成 Web 引用名，点击【添加引用】即可

 

4. 拖拽控件并编写逻辑代码
