在C＃中列出磁盘驱动器及其驱动程序

Question

谁能建议如何列出以下内容，最好在.net列出？

 Driver Letter, Device Driver

我可以使用以下方法获得有关连接到计算机的驱动器的一些相当基本的信息：

DriveInfo[] drives = DriveInfo.GetDrives();

我可以使用WMI获得更多信息，但无法获得与每个驱动器关联的设备驱动程序：

 SelectQuery query = new SelectQuery("select * from win32_DiskDrive");
    ManagementObjectSearcher searcher = new ManagementObjectSearcher(query);

我可以使用Win.OBJECT_DIRECTORY_INFORMATION列出设备ID及其驱动程序，但是我无法将它们映射到驱动器。

通过以下功能，我从http://bloggingabout.net/blogs/ramon/archive/2007/04/05/get-the-physical-path-of-a-path-that-uses-a找到了所需的功能-subst-drive.aspx

    private static string GetRealPath(string path)
{

   string realPath = path;
   StringBuilder pathInformation = new StringBuilder(250);
   string driveLetter = Path.GetPathRoot(realPath).Replace("\\", "");
   QueryDosDevice(driveLetter, pathInformation, 250);

   // If drive is substed, the result will be in the format of "\??\C:\RealPath\".

      // Strip the \??\ prefix.
      string realRoot = pathInformation.ToString().Remove(0, 4);

      //Combine the paths.
      realPath = Path.Combine(realRoot, realPath.Replace(Path.GetPathRoot(realPath), ""));


return realPath;
}


[DllImport("kernel32.dll")]
static extern uint QueryDosDevice(string lpDeviceName, StringBuilder lpTargetPath, int ucchMax);
