是否可以确定 Environment.SpecialFolder.System 驱动器的 Win32_DiskDrive SerialNumber? [英] Is it possible to determine the Win32_DiskDrive SerialNumber of the Environment.SpecialFolder.System drive?

问题描述

我已经兜兜转转了一会儿，似乎也无法在谷歌上找到答案.

I've been going around in circles for a bit now, can't seem to find the answer on google either.

正如标题所说，如果我得到当前正在运行的驱动器号窗口，让我们这样说:Path.GetPathRoot(Environment.GetFolderPath(Environment.SpecialFolder.System));然后我可以确定它的 Win32_DiskDrive SerialNumber 吗?我找不到链接它们的方法.

As the title says, if i get the current drive letter windows is running on, let's say like this: Path.GetPathRoot(Environment.GetFolderPath(Environment.SpecialFolder.System)); Can i then determine its Win32_DiskDrive SerialNumber? I cannot find a way to link them.

那是制造商的 S/N，而不是 VolumeSerialNumber.

That is the manufacturer's S/N not the VolumeSerialNumber.

提前致谢

推荐答案

您可以使用 ManagmentObjectSearch 结合 协会成员声明:

You can use ManagmentObjectSearch combined with ASSOCIATORS OF statement:

public static string GetSerialNumber(string logicalDrive)
{
    using (var partitionsQuery = new ManagementObjectSearcher(string.Format("ASSOCIATORS OF {{Win32_LogicalDisk.DeviceID='{0}'}} WHERE ResultClass = Win32_DiskPartition", logicalDrive)))            
    {
        foreach (var results in partitionsQuery.Get())
        {
            using (var diskDrives = new ManagementObjectSearcher(string.Format("ASSOCIATORS OF {{Win32_DiskPartition.DeviceID='{0}'}} WHERE ResultClass=Win32_DiskDrive", results["DeviceID"])))
            {
                foreach (var d in diskDrives.Get())
                {
                    Console.WriteLine("Serial: " + d["SerialNumber"]);

                    return d["SerialNumber"].ToString();
                }
            }
        }
    }

    return null;
} 

用法:

var num = GetSerialNumber(Path.GetPathRoot(Environment.SystemDirectory).TrimEnd(new [] {'\\'}));

注意:不要忘记从 Path.GetPathRoot 返回的路径中删除反斜杠.

Note: Dont forget to remove backslashes from the path returned by Path.GetPathRoot.
