检测光盘是否在DVD驱动器中
使用WMI来检测是否磁盘在CD/DVD驱动器:
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
:驱动器的光盘设备,如CD或DVD-ROM。 -
Fixed
:驱动器是一个固定磁盘。 -
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。
的一种CD/DVD的/蓝光看到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
- BD-ROM
- BDR
- BD-RE
- 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;
}

How to Detect CD-ROM is loaded in the CD-ROM drive
从上面的链接
using System;
using System.Management;
class Application
{
public static void Main()
{
SelectQuery query =
new SelectQuery("select * from win32_logicaldisk where drivetype=5");
ManagementObjectSearcher searcher =
new ManagementObjectSearcher(query);
foreach(ManagementObject mo in searcher.Get())
{
// If both properties are null I suppose there's no CD
if((mo["volumename"] != null) || (mo["volumeserialnumber"] != null))
{
Console.WriteLine("CD is named: {0}", mo["volumename"]);
Console.WriteLine("CD Serial Number: {0}", mo["volumeserialnumber"]);
}
else
{
Console.WriteLine("No CD in Unit");
}
}
// Here to stop app from closing
Console.WriteLine("\nPress Return to exit.");
Console.Read();
}
}

你是对的,但是当事情已经存在,为什么不我们重复使用它 – 2012-07-10 19:27:24
我已经发布了代码,然后没有必要投下来。 – 2012-07-10 19:29:51

有一种简单的方法可以找到你要找的答案。它被称为搜索。仅在这个网站上就有很多提出的解决方案。 – TheZ 2012-07-10 19:24:52
@Musa - 这个问题不是我要问的。这个问题是关于检测驱动器是CDROM驱动器还是硬盘驱动器。与我所要求的无关 – Icemanind 2012-07-10 19:40:48
