C#检查是否存在USB驱动器

Question

我正在编写一个文件,它提取xml以获取文件名,并需要将这些文件复制到USB驱动器.前两个步骤我能够做到这一点.但问题是:

1. 如何检测是否有USB驱动器
2. 然后检测它是哪个驱动器.

谢谢!

Answer 1

这段代码是另一个方向,但它处理"我如何找到USB驱动器"的问题:

 using System.IO;

// ..

        foreach (DriveInfo removableDrive in DriveInfo.GetDrives().Where(
            d => d.DriveType == DriveType.Removable && d.IsReady))
        {
            DirectoryInfo rootDirectory = removableDrive.RootDirectory;
            string monitoredDirectory = Path.Combine(rootDirectory.FullName, DIRECTORY_TO_MONITOR);
            string localDestDirectory = Path.Combine(destDirectory, removableDrive.VolumeLabel);
            if (!Directory.Exists(localDestDirectory))
                Directory.CreateDirectory(localDestDirectory);
            if (Directory.Exists(monitoredDirectory))
            {
                foreach (string file in Directory.GetFiles(monitoredDirectory))
                {
                    File.Copy(file, Path.Combine(localDestDirectory, Path.GetFileName(file)), true);
                }
            }
        }
