如何检测是否有任何特定的驱动器是硬盘驱动器？

Question

在C＃中，您如何检测特定驱动器是硬盘驱动器，网络驱动器，CDRom还是软盘？

Answer 1

方法GetDrives（）返回一个DriveInfo类，该类具有与System.IO.DriveType的枚举对应的属性DriveType：

public enum DriveType
{
    Unknown,         // The type of drive is unknown.  
    NoRootDirectory, // The drive does not have a root directory.  
    Removable,       // The drive is a removable storage device, 
                     //    such as a floppy disk drive or a USB flash drive.  
    Fixed,           // The drive is a fixed disk.  
    Network,         // The drive is a network drive.  
    CDRom,           // The drive is an optical disc device, such as a CD 
                     // or DVD-ROM.  
    Ram              // The drive is a RAM disk.   
}

以下是来自MSDN的略微调整的示例，显示了所有驱动器的信息：

    DriveInfo[] allDrives = DriveInfo.GetDrives();
    foreach (DriveInfo d in allDrives)
    {
        Console.WriteLine("Drive {0}, Type {1}", d.Name, d.DriveType);
    }

Answer 2

DriveInfo.DriveType 应该有效对你而言。

DriveInfo[] allDrives = DriveInfo.GetDrives();

foreach (DriveInfo d in allDrives)
{
    Console.WriteLine("Drive {0}", d.Name);
    Console.WriteLine("  File type: {0}", d.DriveType);
}

Answer 3

检查 System.IO.DriveInfo 类和DriveType属性。
