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)？
解决方法
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());
从here.
DriveType Enumeration可以帮你什么样的光盘：
> CDRom：驱动器是光盘设备,例如CD或DVD-ROM.
>修正：驱动器是固定磁盘.
>网络：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.
>可移动：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.
>未知：驱动器类型未知.
对于CD / DVD /蓝光的种类见IMAPI_MEDIA_PHYSICAL_TYPE enumeration：
>未知
> CDROM
> CDR
> CDRW
> DVDROM
> DVDRAM
> DVDPLUSR
> DVDPLUSRW
> DVDPLUSR_DUALLAYER
> DVDDASHR
> DVDDASHRW
> DVDDASHR_DUALLAYER
>磁盘
> DVDPLUSRW_DUALLAYER
> HDDVDROM
> HDDVDR
> HDDVDRAM
> BDROM
> BDR
> BDRE
> MAX
你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;
}
