C# Signature:
[DllImport("Kernel32.dll", CharSet = CharSet.Auto, SetLastError = true)]
extern static bool GetVolumeInformation(
string RootPathName,
StringBuilder VolumeNameBuffer,
int VolumeNameSize,
out uint VolumeSerialNumber,
out uint MaximumComponentLength,
out uint FileSystemFlags,
StringBuilder FileSystemNameBuffer,
int nFileSystemNameSize);
User-Defined Types:
None.
Notes:
The VolumeSerialNumber is not optional with this signature!!!
Tips & Tricks:
If you specify RootPathName as a driveletter (eg not a volume name) then you have to terminate it with a backslash.
Sample Code:
StringBuilder volname = new StringBuilder(256);
StringBuilder fsname = new StringBuilder(256);
uint sernum, maxlen, flags;
if(!GetVolumeInformation("c:\\", volname.Capacity, out sernum, out maxlen, out flags, fsname, fsname.Capacity))
Marshal.ThrowExceptionForHR(Marshal.GetHRForLastWin32Error());
string volnamestr = volname.ToString();
string fsnamestr = fsname.ToString();
