How do I detect a USB drive letter from a c# application?

问题

How to detect the USB drive letter from c# program which is not residing in the USB? The program should reside in the system, if multiple USB's are connected then i should first able to get the manufacturer name also.

回答1:

This will get all of the removable drives attached (including USB drives):

foreach (DriveInfo drive in DriveInfo.GetDrives())
{
    if (drive.DriveType == DriveType.Removable)
    {
        // Code here
    }
}

Getting the USB drive manufacturer may be more difficult, and you may need to use WMI.

Edit: Here are 2 links on reading USB drive information:

• how to determine USB Flash drive manufacturer?
• Finding serial number of USB drive without WMI

回答2:

List<string> list_usb= DriveInfo.GetDrives().Where(d => d.DriveType.ToString() == "Removable").Select(d => d.Name).ToList();

            foreach(var i in list_usb)
            {
                Console.WriteLine(i);
            }

you can try this.
