Getting Drive's Volume Information using C#


First of all, I want to say sorry for my poor English. In this article, I try to explain how to get the volume information of our logical drives by using kernel32.dll.


This DLL supports capabilities that are associated with OS such as:

  • Process loading
  • Context switching
  • File I/O
  • Memory management


This function is used to get the volume information of drive. It gives serial number, volume name and file type.

The following is the declaration of GetVolumeInformation function:

[DllImport("kernel32.dll", CharSet = CharSet.Auto)]
static extern bool GetVolumeInformation(string Volume, StringBuilder VolumeName, 
	uint VolumeNameSize, out uint SerialNumber, out uint SerialNumberLength, 
	out uint flags, StringBuilder fs, uint fs_size);

DllImport is used to import the kernel32.dll file. The out variable SerialNumber will return the serial number of a given drive. Here, the following code will explain how to get volume information of a given drive.

uint serialNum, serialNumLength, flags;
StringBuilder volumename = new StringBuilder(256);
StringBuilder fstype = new StringBuilder(256); 

bool ok = = GetVolumeInformation(drives, volumename, 
	(uint)volumename.Capacity - 1, out serialNum, out serialNumLength, 
	out flags, fstype, (uint)fstype.Capacity - 1);

if (ok)
  lblVolume.Text = lblVolume.Text + "\n Volume Information of " + drives + "\n";
  lblVolume.Text = lblVolume.Text + "\nSerialNumber of is..... " + 
	serialNum.ToString() + " \n";
   if (volumename != null)
   lblVolume.Text = lblVolume.Text + "VolumeName is..... " + 
	volumename.ToString() + " \n";
if (fstype != null)
 lblVolume.Text = lblVolume.Text + "FileType is..... " + fstype.ToString() + " \n";

Hope this will help you. :)
