怎样取得硬盘序列号？请给源码。谢谢

Answer 1

procedure TForm1.Button1Click(Sender: TObject);
 var
   VolumeSerialNumber : DWORD;
   MaximumComponentLength : DWORD;
   FileSystemFlags : DWORD;
   SerialNumber : string;
 begin
   GetVolumeInformation('C:\',
                        nil,
                        0,
                        @VolumeSerialNumber,
                        MaximumComponentLength,
                        FileSystemFlags,
                        nil,
                        0);
   SerialNumber := IntToHex(HiWord(VolumeSerialNumber), 4) +
                   '-' +
                   IntToHex(LoWord(VolumeSerialNumber), 4);
   Memo1.Lines.Add(SerialNumber);end;
