我怎么能确定给定的驱动器盘符是本地/映射/ USB驱动器？ [英] How can I determine if a given drive letter is a local/mapped/usb drive?

问题描述

给定一个驱动器的盘符，我怎么能确定它是什么类型的驱动器？即无论是E：\是USB驱动器，网络驱动器或本地硬盘驱动器

Given the letter of a drive, how can I determine what type of drive it is? I.e. whether E:\ is a usb drive, a network drive or a local hard drive.

推荐答案

看一看<一个HREF =htt​​p://msdn.microsoft.com/en-us/library/system.io.driveinfo.drivetype.aspx> DriveInfo 的 的DriveType 财产。

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;
    }
}
