Question

我想检索系统中的固定磁盘列表。但是C＃的GetDrives固定驱动器包括USB硬盘插头。

我知道如何检测到固定硬盘不是USB硬盘，反之亦然？

Answer 1

解决方案来自How to get serial number of USB-Stick in C#：

 //import the System.Management namespace at the top in your "using" statement.
 ManagementObjectSearch theSearcher = new ManagementObjectSearcher(
      "SELECT * FROM Win32_DiskDrive WHERE InterfaceType='USB'");

Answer 2

使用DriveType检测驱动器的类型：

using System.IO;

DriveInfo[] allDrives = DriveInfo.GetDrives();
foreach (DriveInfo d in allDrives)
{
  if (d.IsReady && d.DriveType == DriveType.Fixed)
  {
    // This is the drive you want...
  }
}

DriveInfo Class

您可以在此处获取USB硬盘列表。

currentTime()

您可以在此处获取所有固定驱动器（系统和USB硬盘）的列表：

//Add Reference System.Management and use namespace at the top of the code.
ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive WHERE InterfaceType='USB'");

        foreach (ManagementObject queryObj in searcher.Get())
        {
            foreach (ManagementObject b in queryObj.GetRelated("Win32_DiskPartition"))
            {
                foreach (ManagementBaseObject c in b.GetRelated("Win32_LogicalDisk"))
                { 
                    Console.WriteLine(String.Format("{0}" + "\\", c["Name"].ToString())); // here it will print USB drive letter
                }
            }

        }

如果你比较它们，那么你可以检索系统中没有USB硬盘的固定磁盘列表。
