Question

This is the code that I have for my query:

public String getDriveID()
{
    String wow = @"win32_logicaldisk.deviceid=\" + @driveID;

    ManagementObject disk = new ManagementObject(wow);
    disk.Get();
    Console.WriteLine(disk["Name"]);
    return disk["Name"].ToString();
}

And this is what creates the driveID String that the method uses:

DriveInfo dInfo = therehasgottobeanotherway[driveList.SelectedIndex];

if (dInfo.IsReady) {
    diskWMI dwmi = new diskWMI(dInfo.Name);
}

If you’re not familiar with the DriveInfo class, the Name attribute returns the name of the drive, for example c:\

I found this code online that does the EXACT same thing I’m trying to do, but I always get an error when I’m trying to use it:

ManagementObject disk = new ManagementObject("win32_logicaldisk.deviceid=\"c:\"");
disk.Get();
Console.WriteLine(disk["VolumeName"]);
Console.ReadLine();

I bet there is a formatting error happening but I can’t figure out what to change.

I’m trying to pass in a drives name where it has deviceid=

Answer 1

public string GetHDDSerialNumber(string drive)
{
    //check to see if the user provided a drive letter
    //if not default it to "C"
    if (drive == "" || drive == null)
    {
        drive = "C";
    }
    //create our ManagementObject, passing it the drive letter to the
    //DevideID using WQL
    ManagementObject disk = new ManagementObject("Win32_LogicalDisk.DeviceID=\"" + drive + ":\"");
    //bind our management object
    disk.Get();
    //return the serial number
    return disk["VolumeSerialNumber"].ToString();
}

or for your existing example this will work for you

String drive = "c";
ManagementObject disk = new ManagementObject("Win32_LogicalDisk.DeviceID=\"" + drive + ":\"");
disk.Get();
Console.WriteLine(disk["VolumeName"]);
Console.ReadLine();
