监控PenDrive操作

Question

网。我开发了一个C＃项目来监控Pen-drive动作。 通过使用wndproc方法，我发现usb插件并通过设备更改事件发生插件操作。但我不知道如何找到从笔式驱动器复制到PC的所有文件，反之亦然，并且还会阻止用户在插入pendrive后的特定时间访问笔式驱动器。请提供解决方案或任何想法。提前致谢。对不起，我的英语不好。我在

下面提供了设备更改事件的示例代码

protected override void WndProc(ref Message m)
        {
            try
            {
                var drvs = DriveInfo.GetDrives().Where(drives => drives.IsReady && drives.DriveType == DriveType.Removable);

                //0x0219 device change.
                //0x8000 device arrival.
                //0x8004 device removal complete.
                //0x00000002 device type volume.
                /*if (m.Msg == 0x0219)
                {
                    ejectUSB();
                    /*if (m.Msg == 0x8004)
                    {
                        Thread thread = new Thread(ejectUSB);
