用c#怎样获得固定光驱和usb光驱的序列号

Question

需要用代码获得一个能唯一标志光驱的东西，谢谢。

Answer 1

Hi,

你可以尝试安装 System.Management Nuget包，并使用以下代码获取光驱的设备ID。

    ManagementObjectSearcher searcher = new ManagementObjectSearcher("root\\CIMV2", "SELECT * FROM Win32_CDROMDrive");
    foreach (ManagementObject queryObj in searcher.Get())
    {
        Console.WriteLine("DeviceID: {0}", queryObj["DeviceID"]);
    }

Regards,

Kyle

Answer 2

谢谢。顺便问一句，为什么是DeviceID，不是SerialNumber

Answer 3

我对我的光驱测试了你的代码。

serial number字段没有值，DevideID和PNPDevideID具有相同的值，但是长度太长了。这个值被反斜杠分成三个子串。

我该怎么做。

Answer 4

>> 这个值被反斜杠分成三个子串

这句话是什么意思？在获取的ID字符串中本身就包含有反斜杠'\'。你可以在设备管理器中查看到对应的属性信息。

Answer 5

如果我把这个光驱安装到别的电脑上，这个光驱的DeviceID会变化吗？

Answer 6

不会。DeviceID属于硬件属性，与所处的系统环境无关。

Answer 7

这个DeviceID太长了。

我目前任务是管理公司固定资产包括光驱，需要把光驱的唯一标识登记在册。我如果要登记DeviceID，太长了。
