如何检测是否任何特定的驱动器是硬盘驱动器？ [英] How to detect if any specific drive is a hard drive?

问题描述

在C＃中如何检测是一个特定的驱动器是硬盘驱动器，网络驱动器，CD-ROM或软盘？

In C# how do you detect is a specific drive is a Hard Drive, Network Drive, CDRom, or floppy?

推荐答案

该方法GetDrives（）函数返回一个拥有对应System.IO.DriveType枚举属性的DriveType一个DriveInfo类：

The method GetDrives() returns a DriveInfo class which has a property DriveType that corresponds to the enumeration of System.IO.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.   
}

下面是从MSDN一个小幅调整的例子，显示所有驱动器的信息：

Here is a slightly adjusted example from MSDN that displays information for all drives:

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