c# - 如何检测任何特定驱动器是否为硬盘驱动器？

Question

在 C# 中，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，它有一个属性 DriveType，对应于 System.IO.DriveType 的枚举:

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.   
}

这里是来自 MSDN 的一个略微调整的示例，它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);
    }
