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

Question

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.

Answer 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.

Answer 2

Thanks Jon. But please give me some hint on WMI.

Suppose i can handle this way:

1. Pass a particular manufacturer name as a paramater and get the drive letter for which this manufacturer name matches.

Please assist.

Thanks in advance.
