获取启动驱动器的序列号和其他信息

Question

我正在尝试获取启动驱动器的序列号，但我还不知道该怎么做。

我确实知道分区 =\= 硬盘驱动器，但我想要启动分区的序列号。

这是我到目前为止所拥有的：

        var searcher = new ManagementObjectSearcher("SELECT * FROM Win32_PhysicalMedia");

        int i = 0;
        foreach (ManagementObject wmi_HD in searcher.Get())
        {
            // get the hardware serial no.
            if (wmi_HD["SerialNumber"] == null)
                richTextBox1.Text += "None" + Environment.NewLine;
            else
                richTextBox1.Text += "Name: " + wmi_HD["Name"] + Environment.NewLine;
                richTextBox1.Text += "SerialNumber: " + wmi_HD["SerialNumber"] + Environment.NewLine;
                richTextBox1.Text += "MediaType: " + wmi_HD["MediaType"] + Environment.NewLine;
                richTextBox1.Text += "Removable: " + wmi_HD["Removable"] + Environment.NewLine;

            ++i;
        }

我在这里查看：

看看我是否可以看到它是引导驱动器，我什么也没看到。

除了序列号之外，我没有得到任何回报，其他一切都是空白的。

这就是我从上面的代码中得到的结果：

姓名：

序列号：5YZ01J34

如何获取启动驱动器的序列号以及上面未显示的信息？

再次感谢！

Answer 1

这里您谈论的是驱动器（因为它是可引导的），而不是磁盘。驱动器是逻辑，由字母（C、D...等）表示，磁盘是物理，由数字（从 0 到 N）表示）。
在您的示例中，您使用了 WMI 和 Win32_PhysicalMedia，这是错误的，因为此类与磁盘有关，而不是驱动器。

以下是您希望使用 P/Invoke 实现的功能：

namespace ConsoleApplication3
{
    using System.Runtime.InteropServices;
    using System.Text;

    public class Drive
    {
        [DllImport("kernel32.dll", CharSet = CharSet.Auto, SetLastError = true)]
        private static extern bool GetVolumeInformation(
            string rootPathName,
            StringBuilder volumeNameBuffer,
            int volumeNameSize,
            ref uint volumeSerialNumber,
            ref uint maximumComponentLength,
            ref uint fileSystemFlags,
            StringBuilder fileSystemNameBuffer,
            int nFileSystemNameSize);

        public string VolumeName { get; private set; }

        public string FileSystemName { get; private set; }

        public uint SerialNumber { get; private set; }

        public string DriveLetter { get; private set; }

        public static Drive GetDrive(string driveLetter)
        {
            const int VolumeNameSize = 255;
            const int FileSystemNameBufferSize = 255;
            StringBuilder volumeNameBuffer = new StringBuilder(VolumeNameSize);
            uint volumeSerialNumber = 0;
            uint maximumComponentLength = 0;
            uint fileSystemFeatures = 0;
            StringBuilder fileSystemNameBuffer = new StringBuilder(FileSystemNameBufferSize);

            if (GetVolumeInformation(
                string.Format("{0}:\\", driveLetter),
                volumeNameBuffer,
                VolumeNameSize,
                ref volumeSerialNumber,
                ref maximumComponentLength,
                ref fileSystemFeatures,
                fileSystemNameBuffer,
                FileSystemNameBufferSize))
            {
                return new Drive
                    {
                        DriveLetter = driveLetter,
                        FileSystemName = fileSystemNameBuffer.ToString(),
                        VolumeName = volumeNameBuffer.ToString(),
                        SerialNumber = volumeSerialNumber
                    };
            }

            // Something failed, returns null
            return null;
        }
    }
}


Drive drive = Drive.GetDrive("C");

Console.WriteLine(string.Format("Volumne name: {0}", drive.VolumeName));
Console.WriteLine(string.Format("File system name: {0}", drive.FileSystemName));
Console.WriteLine(string.Format("SerialNumber: {0:X}", drive.SerialNumber));

• 如果您想了解有关驱动器的更多信息，可以使用 DeviceIoControl 与 IOCTL_DISK_GET_DRIVE_GEOMETRY 获取的控制代码关联磁盘的几何结构（每个簇的字节数、每个磁道的扇区...）。
• 您还可以使用 IOCTL_DISK_GET_PARTITION_INFO 控制代码。

现在，使用 WMI 进行同样的操作：

var searcher = new ManagementObjectSearcher("SELECT * FROM Win32_LogicalDisk");

foreach (ManagementObject drive in searcher.Get())
{
    Console.WriteLine("-------");
    Console.WriteLine(string.Format("VolumeName: {0}", drive["VolumeName"]));
    Console.WriteLine(string.Format("VolumeSerialNumber: {0}", drive["VolumeSerialNumber"]));
    Console.WriteLine(string.Format("MediaType: {0}", drive["MediaType"]));
    Console.WriteLine(string.Format("FileSystem: {0}", drive["FileSystem"]));
}

注意我使用了 Win32_LogicalDisk，因为我们正在谈论驱动器（此处称为逻辑磁盘）。

    public static string Mtd_GetDriveLetterWithLabel(string DriveLabel)
{
    ManagementObjectSearcher DriveLabelQuery = new ManagementObjectSearcher(" SELECT * FROM Win32_Volume WHERE Label = '" + DriveLabel + "' ");

    string DriveLetter = "";
    foreach (ManagementObject DriveLabels in DriveLabelQuery.Get())
    {
        DriveLetter = DriveLabels["DriveLetter"].ToString();
    }
    return DriveLetter;
}




public static int Mtd_GetDiskNumberWithLetter(string DriveLetter)
{
    ManagementObjectSearcher DriveLetterGeneralQuery = new ManagementObjectSearcher("SELECT * FROM Win32_LogicalDiskToPartition");
    ManagementObjectCollection DriveLetterCollection = DriveLetterGeneralQuery.Get();

    string Dependent = @"\\" + Environment.MachineName + "\\root\\cimv2:Win32_LogicalDisk.DeviceID=\"" + DriveLetter + "\"";
    String DiskNumberTxt = "";
    foreach (ManagementObject DiskNumbers in DriveLetterCollection)
    {
        if ((DiskNumbers["Dependent"].ToString()) == Dependent)
        {
            DiskNumberTxt = DiskNumbers["Antecedent"].ToString();
        }
    }

    int From = DiskNumberTxt.IndexOf("Disk #") + "Disk #".Length;
    int To = DiskNumberTxt.IndexOf(",");
    String DiskNumberTrim = DiskNumberTxt.Substring(From, To - From);

    int DiskNumber = Int32.Parse(DiskNumberTrim);
    return DiskNumber;
}




public static string Mtd_GetSerialNumberWithDiskNumber(int DiskNumber)
{
    ManagementObjectSearcher SerialNumberQuery = new ManagementObjectSearcher("SELECT * FROM Win32_PhysicalMedia");
    ManagementObjectCollection SerialNumberCollection = SerialNumberQuery.Get();

    string Tag = @"\\.\PHYSICALDRIVE" + DiskNumber;
    String SerialNumberTxt = "";

    foreach (ManagementObject SerialNumbers in SerialNumberCollection)
    {
        if ((SerialNumbers["Tag"].ToString()) == Tag)
        {
            SerialNumberTxt = SerialNumbers["SerialNumber"].ToString();
        }
    }
    return SerialNumberTxt;
}



string DriveLabel = "DATA";
 
string DriveLetter = Mtd_GetDriveLetterWithLabel(DriveLabel);
            Console.WriteLine(DriveLetter);
                       
int DiskNumber = Mtd_GetDiskNumberWithLetter(DriveLetter);
Console.WriteLine(DiskNumber);

string DiskSerialNumber = Mtd_GetSerialNumberWithDiskNumber(DiskNumber);
Console.WriteLine(DiskSerialNumber);
