获取本机MAC地址-优快云博客

本文提供了两种在Delphi中获取本机MAC地址的方法。一种是通过调用UuidCreate函数并解析返回的GUID来获取MAC地址；另一种是利用Delphi内置的netbios函数，通过NCBASTAT命令获取适配器状态并从中读取MAC地址。

获取本机MAC地址方法一：

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;
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.

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;
end;
