告诉如果驱动器分区或硬盘分开 [英] Tell if a Drive is a partition or a separate HDD

问题描述

我写我自己的文件搜索（为什么？因为我想/能 - 不找一个现有的程序）。我可以通过使用 DriveInfo获得在C＃中的所有驱动器。 GetDrives（）方法。理想情况下，我想只在是独立​​的磁盘驱动器，并为同一驱动器上运行它们的顺序分区并行运行搜索。这样，我不会对不断追求的GetDrives驱动器返回的所有分区或可移动介质。我知道我可以告诉大家，如果它是一个USB驱动器与一个硬盘的类型？我怎样才能做到这将DriveInfo或任何其他方法，它

I am writing my own file search (why because I want to / can - not looking for an existing program). I can get all the drives in c# by using the DriveInfo.GetDrives() method. Ideally I would like to run the search in parallel only on drives that are separate disk and for partitions that are on the same drive run them sequential. This way I will not cause the drives on constantly seek as the GetDrives returns all partitions or removable media. I know I can tell the type if it is a USB Drives vs. a HDD? How can I accomplish this will the DriveInfo or any other methodology that?

推荐答案

的此相关的问题展示了如何找出使用WMI（在 System.Management ）：

This related question shows how to find out using WMI (found in System.Management):

var searcher = new ManagementObjectSearcher("root\\CIMV2", "SELECT * FROM Win32_DiskPartition");

foreach (var queryObj in searcher.Get())
{
    Console.WriteLine("-----------------------------------");
    Console.WriteLine("Win32_DiskPartition instance");
    Console.WriteLine("Name:{0}", (string)queryObj["Name"]);
    Console.WriteLine("Index:{0}", (uint)queryObj["Index"]);
    Console.WriteLine("DiskIndex:{0}", (uint)queryObj["DiskIndex"]);
    Console.WriteLine("BootPartition:{0}", (bool)queryObj["BootPartition"]);
}
