C#定义USB路径

Question

我需要在 C# windows 应用程序中设置 USB 驱动器的默认路径。

我已经尝试获取应用程序路径和文档路径

string fileName = @"" + Application.StartupPath + "\Config1.txt";

string folp = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);

如何定义USB路径 Like Application Path

Answer 1

您可以像这样设置当前目录：

SetCurrentDirectory("X:\MyUsbFolder");

详情见this page。

Answer 2

您可以只查找 DriveType.Removable with DriveInfo.GetDrives

var removableDrives = DriveInfo.GetDrives()
                               .Where(x => x.DriveType == DriveType.Removable)
                               .Select(x => x.RootDirectory)
                               .ToList();

if (removableDrives.Any())
{
   string myPath = Path.Combine(removableDrives[0].FullName, "Config1.txt");
}

显然，您必须处理没有（或多个）可移动驱动器的情况，但我会将这些细节留给您。

DriveType Enumeration

Removable

The drive is a removable storage device, such as a floppy disk drive or a USB flash drive.

DriveInfo.GetDrives Method ()

Retrieves the drive names of all logical drives on a computer

Remarks

This method retrieves all logical drive names on a computer. You can use this information to iterate through the array and obtain information on the drives using other DriveInfo methods and properties. Use the IsReady property to test whether a drive is ready because using this method on a drive that is not ready will throw a IOException.

Answer 3

您可以获得所有可移动驱动器，然后像这样获取它们的盘符：

 foreach (DriveInfo drive in DriveInfo.GetDrives())
 {
     if (drive.DriveType == DriveType.Removable)
     {
        Console.WriteLine(drive.Name);
     }
 }
