private void FindUsb()
       {
           //string []Logicdriver = Environment.GetLogicalDrives();
           DriveInfo[] driveinfo = DriveInfo.GetDrives();
           for (int i = 0; i < driveinfo.Length; i ++ )
           {
               switch (driveinfo[i].DriveType.ToString())
               {
                   case "Fixed"://固定磁盘
                       break;
                   case "Removable"://移动硬盘
                       break;
                   case "NetWork": //网络磁盘
                       break;
                   case "CDRom"://光盘设备
                       break;
                   case "Unknown"://未知设备
                       break;
                   default:
                       break;

}
}

}

另外还可以重载winProc()来获得有磁盘插入。
