获取本机MAC地址方法一：
view plaincopy to clipboardprint?
function MacAddress: string;
var
Lib: Cardinal;
Func: function(GUID: PGUID): Longint; stdcall;
GUID1, GUID2: TGUID;
begin
Result := '';
Lib := LoadLibrary('rpcrt4.dll');
if Lib <> 0 then
begin
if Win32Platform <>VER_PLATFORM_WIN32_NT then
@Func := GetProcAddress(Lib, 'UuidCreate')
else @Func := GetProcAddress(Lib, 'UuidCreateSequential');
if Assigned(Func) then
begin
if (Func(@GUID1) = 0) and
(Func(@GUID2) = 0) and
(GUID1.D4[2] = GUID2.D4[2]) and
(GUID1.D4[3] = GUID2.D4[3]) and
(GUID1.D4[4] = GUID2.D4[4]) and
(GUID1.D4[5] = GUID2.D4[5]) and

获得本机MAC地址方法二：
在delphi的nb30.pas单元中,包含了对netbios协议的完全支持，在该单元中定义了一个名为netbios的函数,通过该函数就能够得到本机的MAC地址.
view plaincopy to clipboardprint?
function GetNetBIOSAddress : string;
var ncb : TNCB;
status : TAdapterStatus;
lanenum : TLanaEnum;
procedure ResetAdapter (num : char);
begin
fillchar(ncb,sizeof(ncb),0);
ncb.ncb_command:=char(NCBRESET);
ncb.ncb_lana_num:=num;
Netbios(@ncb);
end;
var
i:integer;
lanNum : char;
address : record
part1 : Longint;
part2 : Word;
end absolute status;
begin
Result:='';
fillchar(ncb,sizeof(ncb),0);
ncb.ncb_command:=char(NCBENUM);
ncb.ncb_buffer:=@lanenum;
ncb.ncb_length:=sizeof(lanenum);
Netbios(@ncb);
if lanenum.length=#0 then exit;
lanNum:=lanenum.lana[0];
ResetAdapter(lanNum);
fillchar(ncb,sizeof(ncb),0);
ncb.ncb_command:=char(NCBASTAT);
ncb.ncb_lana_num:=lanNum;
ncb.ncb_callname[0]:='*';
ncb.ncb_buffer:=@status;
ncb.ncb_length:=sizeof(status);
Netbios(@ncb);
ResetAdapter(lanNum);
for i:=0 to 5 do
begin
result:=result+inttoHex(integer(Status.adapter_address[i]),2);
if (i<5) then
result:=result+'-';
end;
