启用/禁用网卡网络连接 (C# 2005)

    今天朋友让我帮他做一个自动禁用/启用网络连接的小软件，因为他的电驴下载东西的时候，网络总断。解决原理可用PING命令不停PING某一网站，当不通时则启用/禁用网络连接。

但是让人郁闷的是，找了一天竟然没发现一个可以让网卡开启和关闭的代码。通过netsh也无法达到效果，XP下使用netsh根本就不能用。郁闷之极。。测试了几段代码，都无效。

    打算放弃的时候，发现了一段小程序，使用的是模拟鼠标按键的原理，打开控制面板，获取面板里的列表，找到网络连接并打开，再到想要关闭的相应项中模拟右键和左键。。很多都是硬编码，但是却实现了这个功能！~~

代码如下：

这篇文章算是抛砖引玉吧，因为里面用到的模拟按键的功能感觉挺实用的。。。
