如何从驱动器全名获取驱动器号

如何在 Windows 下使用 C# 从驱动器（例如 WORKMEMORYSTICK）的已知全名（如果存在）获取驱动器号（例如 F:\）？

即使反过来也是一个开始。

DriveInfo 类公开获取所有可用驱动器的方法（GetDrives），您可以枚举这些与给定字符串匹配的内容。像下面这样的东西应该可以帮助你到达那里：

DirectoryInfo root;
var drives = DriveInfo.GetDrives();
foreach (var drive in drives)
{
    if (drive.VolumeLabel == label)
    {
        root = drive.RootDirectory;
        break;
    }
}

正如 abatishchev 所提到的，由于我孩子的时间要求，最初没有详细说明，存在一个潜在的问题，因为你只会匹配 first< /em> 具有该标签的驱动器，因此，如果您的系统需要它，则需要在逻辑中考虑这一点（不过，确定两个驱动器中的哪一个是所需的驱动器仅基于非-唯一的字符串并不比猜测更好，或者作为我在下面提到，询问用户（如果这是输入）他们的意思是哪一个。）

The DriveInfo class exposes a method to get all available drives (GetDrives), you could enyumerate these an match your given string. Something like the following ought to help get you there:

DirectoryInfo root;
var drives = DriveInfo.GetDrives();
foreach (var drive in drives)
{
    if (drive.VolumeLabel == label)
    {
        root = drive.RootDirectory;
        break;
    }
}

As mentioned by abatishchev, and not initially elaborated on due to the time requirements of my children, there is a potential problem in that you're only going to match the first drive which has that label, therefore you will need to account for this in your logic if your system requires it (though, determining which of two drives is the desired drive based on nothing but a non-unique string is no better than a guess, or as I mention below, asking the user (if this is input) which one they meant.)
