我已经尝试了一切，但我无法获得 pendrive 的路径。

这是我的代码：

var deviceList = mUsbManager.DeviceList;
IEnumerator<UsbDevice> deviceIterator = deviceList.Values.GetEnumerator();

while (deviceIterator.MoveNext())
{
    UsbDevice device = deviceIterator.Current;

    var mPermissionIntent = PendingIntent.GetBroadcast(this.ApplicationContext, 0, new Intent(ACTION_USB_PERMISSION), 0);

    UsbManager mUsbManager = (UsbManager)this.GetSystemService(Context.UsbService);
    mUsbManager.RequestPermission(device, mPermissionIntent);

    bool perm = mUsbManager.HasPermission(device);
    if (perm)
    {
        Java.Lang.Process process = Runtime.GetRuntime().Exec("ls /storage/7EFA-0EB6");
        BufferedReader buffer = new BufferedReader(new InputStreamReader(process.InputStream));

        string listOfFiles = "";
        string line;

        while ((line = buffer.ReadLine()) != null)
        {
            listOfFiles += line + "\n";
        }

        txt.Text += listOfFiles;

        var alrt = Toast.MakeText(this as Context, "\n" + process + "\n"+listOfFiles + "this Path ", ToastLength.Long);
        alrt.SetGravity(Android.Views.GravityFlags.Center, 0, 0);
        alrt.Show();
    }
}

此外，我无法使用制造商定义的挂载点。喜欢 ：

/storage/UsbDriveA  
/storage/USBstorage1
/storage/usbdisk    
/storage/usbotg     
/storage/UDiskA     
/storage/usb-storage
/storage/usbcard    
/storage/usb

正如你在这里看到的，我已经把它写成了硬编码。

自两周以来，我就陷入了困境。

我只需要从笔式驱动器中复制一些图像文件并将其存储在应用程序数据中。
