1.使用Dll中的API函数:
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 (GUID1.D4[6] = GUID2.D4[6]) and (GUID1.D4[7] = GUID2.D4[7]) then begin Result := IntToHex(GUID1.D4[2], 2) + '-' + IntToHex(GUID1.D4[3], 2) + '-' + IntToHex(GUID1.D4[4], 2) + '-' + IntToHex(GUID1.D4[5], 2) + '-' + IntToHex(GUID1.D4[6], 2) + '-' + IntToHex(GUID1.D4[7], 2); end; end; FreeLibrary(Lib); end; end;
2.使用NB30单元:
uses NB30;
function GetAdapterInfo(Lana: Char): String; var Adapter: TAdapterStatus; NCB: TNCB; begin FillChar(NCB, SizeOf(NCB), 0); NCB.ncb_command := Char(NCBRESET); NCB.ncb_lana_num := Lana; if Netbios(@NCB) <> Char(NRC_GOODRET) then begin Result := 'mac not found'; Exit; end;
FillChar(NCB, SizeOf(NCB), 0); NCB.ncb_command := Char(NCBASTAT); NCB.ncb_lana_num := Lana; NCB.ncb_callname := '*';
FillChar(Adapter, SizeOf(Adapter), 0); NCB.ncb_buffer := @Adapter; NCB.ncb_length := SizeOf(Adapter); if Netbios(@NCB) <> Char(NRC_GOODRET) then begin Result := 'mac not found'; Exit; end; Result := IntToHex(Byte(Adapter.adapter_address[0]), 2) + '-' + IntToHex(Byte(Adapter.adapter_address[1]), 2) + '-' + IntToHex(Byte(Adapter.adapter_address[2]), 2) + '-' + IntToHex(Byte(Adapter.adapter_address[3]), 2) + '-' + IntToHex(Byte(Adapter.adapter_address[4]), 2) + '-' + IntToHex(Byte(Adapter.adapter_address[5]), 2); end;
function GetMACAddress: string; var AdapterList: TLanaEnum; NCB: TNCB; begin FillChar(NCB, SizeOf(NCB), 0); NCB.ncb_command := Char(NCBENUM); NCB.ncb_buffer := @AdapterList; NCB.ncb_length := SizeOf(AdapterList); Netbios(@NCB); if Byte(AdapterList.length) > 0 then Result := GetAdapterInfo(AdapterList.lana[0]) else Result := 'mac not found'; end;
