我给你们提供一个思路吧,能不能调用底层的API实现功能?
1、C#能操作底层么??? 如监控U盘插入拔出、光驱监控的问题
http://topic.csdn.net/u/20080513/14/765d9fe1-474e-4d1b-8605-017fc960a01a.html?88492
2、监视U盘,子类中不行,主窗体中可以,为什么?在线等!
http://topic.csdn.net/u/20100524/11/585c5187-8d2b-4395-8686-9d2ed03cb2d2.html?80311
3、重写OnWndProc方法,捕获WM_DEVICECHANGED
U盘加载,卸载,拔出,插入,WM_DEVICECHANGE,WndProc,DBT_DEVICEARRIVAL,DBT_DEVICEREMOVECOMPLETE
http://www.cnblogs.com/SunYu/archive/2010/04/29/1723962.html
4、检测U盘插入并自动复制U盘里文件到D盘 C#源码
