c# - 检测路径是否指向 NTFS 分区

给定绝对文件系统路径，我如何检测它是否在 NTFS 分区上？我更喜欢 C# 的帮助，但 Win32/C 会做。软件运行的系统为Windows Vista或更高版本。

//Get all the drives on the local machine.
DriveInfo[] allDrives = DriveInfo.GetDrives();

//Get the path root.

//Find the drive based on the path root.
var driveBasedOnPath = allDrives.FirstOrDefault(d => d.RootDirectory.Name == pathRoot);
//Determine if NTFS  
var isNTFS = driveBasedOnPath != null ? driveBasedOnPath.DriveFormat == "NTFS" : false;
