    int VolumeNameSize,
    out uint VolumeSerialNumber,
    out uint MaximumComponentLength,
    out uint FileSystemFlags,
    StringBuilder FileSystemNameBuffer,

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();
