以编程方式在vb.net或c＃中弹出和缩回CD驱动器

有没有办法这样做？ 我知道有可能以编程方式弹出/收回CD驱动器SOMEHOW，因为当Roxio提示我插入磁盘时会这样做。

c＃或vb.net都是首选，但c和c ++也是最后的选择。

我几乎肯定有一些方法可以做到这一点，我只是不知道要调用的方法。

我确实理解这是一个有点不同寻常的要求，因为当我搜索这些方法时谷歌绝对没有任何结果……

Answer 1

using System.Runtime.InteropServices; [DllImport("winmm.dll")] static extern Int32 mciSendString(String command, StringBuilder buffer, Int32 bufferSize, IntPtr hwndCallback); // To open the door mciSendString("set CDAudio door open", null, 0, IntPtr.Zero); // To close the door mciSendString("set CDAudio door closed", null, 0, IntPtr.Zero);

这是从VB.NET示例转换为已接受的解决方案的替代解决方案：

 using System; using System.IO; using System.Runtime.InteropServices; class Test { const int OPEN_EXISTING = 3; const uint GENERIC_READ = 0x80000000; const uint GENERIC_WRITE = 0x40000000; const uint IOCTL_STORAGE_EJECT_MEDIA = 2967560; [DllImport("kernel32")] private static extern IntPtr CreateFile (string filename, uint desiredAccess, uint shareMode, IntPtr securityAttributes, int creationDisposition, int flagsAndAttributes, IntPtr templateFile); [DllImport("kernel32")] private static extern int DeviceIoControl (IntPtr deviceHandle, uint ioControlCode, IntPtr inBuffer, int inBufferSize, IntPtr outBuffer, int outBufferSize, ref int bytesReturned, IntPtr overlapped); [DllImport("kernel32")] private static extern int CloseHandle(IntPtr handle); static void EjectMedia(char driveLetter) { string path = "\\\\.\\" + driveLetter + ":"; IntPtr handle = CreateFile(path, GENERIC_READ | GENERIC_WRITE, 0, IntPtr.Zero, OPEN_EXISTING, 0, IntPtr.Zero); if ((long) handle == -1) { throw new IOException("Unable to open drive " + driveLetter); } int dummy = 0; DeviceIoControl(handle, IOCTL_STORAGE_EJECT_MEDIA, IntPtr.Zero, 0, IntPtr.Zero, 0, ref dummy, IntPtr.Zero); CloseHandle(handle); } static void Main() { EjectMedia('f'); } }
