Question

是否有一种简单的方法可以检测DVD驱动器中是否插入了光盘？我不在乎什么样的光盘（CD，DVD或蓝光）？

Answer 1

使用WMI检测CD / DVD驱动器中的磁盘：

foreach (var drive in DriveInfo.GetDrives()
                               .Where(d => d.DriveType == DriveType.CDRom))  
MessageBox.Show(drive.Name + " " + drive.IsReady.ToString());

DriveType Enumeration可以帮助您制作什么样的光盘：

CDRom：驱动器是光盘设备，例如CD或DVD-ROM。
Fixed：驱动器是固定磁盘。
Network：驱动器是网络驱动器。
NoRootDirectory驱动器没有根目录。
Ram：驱动器是RAM磁盘。
Removable：驱动器是可移动存储设备，例如软盘驱动器或USB闪存驱动器。
Unknown：驱动器的类型未知。

有关CD / DVD /蓝光的信息，请参阅IMAPI_MEDIA_PHYSICAL_TYPE enumeration：

UNKNOWN
CDROM
CDR
CDRW
DVDROM
DVDRAM
DVDPLUSR
DVDPLUSRW
DVDPLUSR_DUALLAYER
DVDDASHR
DVDDASHRW
DVDDASHR_DUALLAYER
DISK
DVDPLUSRW_DUALLAYER
HDDVDROM
HDDVDR
HDDVDRAM
BDROM
BDR
BD-RE
MAX

您的代码可能是这样的：

public bool IsDiscAvailable(int driveNumber)
{
    MsftDiscMaster2Class discMaster = new MsftDiscMaster2Class();
    string id = discMaster[driveNumber];

    MsftDiscRecorder2Class recorder = new MsftDiscRecorder2Class();
    recorder.InitializeDiscRecorder(id);

    MsftDiscFormat2DataClass dataWriter = new MsftDiscFormat2DataClass();
    if (dataWriter.IsRecorderSupported(recorder))
    {
        dataWriter.Recorder = recorder;
    }
    else
    {
        Console.WriteLine("Recorder not supported");
        return false;
    }
    if (dataWriter.IsCurrentMediaSupported(recorder))
    {
        var media = dataWriter.CurrentPhysicalMediaType;
        if (media == IMAPI_MEDIA_PHYSICAL_TYPE.IMAPI_MEDIA_TYPE_UNKNOWN)
        {
            Console.WriteLine("Unknown media or no disc");
        }
        else
        {
            Console.WriteLine("Found disc type {0}", media);
            return true;
        }
    }
    else
    {
        Console.WriteLine("Disc absent or invalid.");
    }
    return false;
}
