如何确定给定的驱动器号是本地驱动器，映射驱动器还是USB驱动器? [英] How can I determine if a given drive letter is a local, mapped, or USB drive?

问题描述

鉴于驱动器的字母，我如何确定它是哪种类型的驱动器?

Given the letter of a drive, how can I determine what type of drive it is?

例如，E:\是USB驱动器，网络驱动器还是本地硬盘驱动器.

For example, whether E:\ is a USB drive, a network drive or a local hard drive.

推荐答案

看看

Have a look at DriveInfo's DriveType property.

System.IO.DriveInfo[] drives = System.IO.DriveInfo.GetDrives();
foreach (var drive in drives)
{
    string driveName = drive.Name; // C:\, E:\, etc:\

    System.IO.DriveType driveType = drive.DriveType;
    switch (driveType)
    {
        case System.IO.DriveType.CDRom:
            break;
        case System.IO.DriveType.Fixed:
            // Local Drive
            break;
        case System.IO.DriveType.Network:
            // Mapped Drive
            break;
        case System.IO.DriveType.NoRootDirectory:
            break;
        case System.IO.DriveType.Ram:
            break;
        case System.IO.DriveType.Removable:
            // Usually a USB Drive
            break;
        case System.IO.DriveType.Unknown:
            break;
    }
}
