簡介：
function TForm1.NBGetAdapterAddress(a: integer): String;
//a指定多個網卡適配器中的哪一個0，1，2...
Var
NCB:TNCB; // Netbios control block file://NetBios控制塊
ADAPTER : TADAPTERSTATUS; // Netbios adapter status//取網卡狀態
LANAENUM : TLANAENUM; // Netbios lana
intIdx : Integer; // Temporary work value//臨時變數
cRC : Char; // Netbios return code//NetBios返回值
strTemp : String; // Temporary string//臨時變數Begin
// Initialize
Result := '';
Try
// Zero control blocl
ZeroMemory(@NCB, SizeOf(NCB));
// Issue enum command
NCB.ncb_command:=Chr(NCBENUM);
cRC := NetBios(@NCB);
// Reissue enum command
NCB.ncb_buffer := @LANAENUM;
NCB.ncb_length := SizeOf(LANAENUM);
cRC := NetBios(@NCB);
If Ord(cRC)0 Then
exit;
// Reset adapter
ZeroMemory(@NCB, SizeOf(NCB));
NCB.ncb_command := Chr(NCBRESET);
NCB.ncb_lana_num := LANAENUM.lana[a];
cRC := NetBios(@NCB);
If Ord(cRC)0 Then
exit;
// Get adapter address
ZeroMemory(@NCB, SizeOf(NCB));
NCB.ncb_command := Chr(NCBASTAT);
NCB.ncb_lana_num := LANAENUM.lana[a];
StrPCopy(NCB.ncb_callname, '*');
NCB.ncb_buffer := @ADAPTER;
NCB.ncb_length := SizeOf(ADAPTER);
cRC := NetBios(@NCB);
// Convert it to string
strTemp := '';
For intIdx := 0 To 5 Do
strTemp := strTemp + InttoHex(Integer(ADAPTER.adapter_address[intIdx]),2);
Result := strTemp;
Finally
End;最後別忘了uses nb30.pas
經測試，98,2000下皆可用

在iphlpapi.dll里面有一个函数：GetAdaptersInfo()
好像是干这个用的。说明如下：GetAdaptersInfoThe GetAdaptersInfo function retrieves adapter information for the local computer.DWORD GetAdaptersInfo(PIP_ADAPTER_INFO pAdapterInfo, // buffer to receive dataPULONG pOutBufLen // size of data returned);ParameterspAdapterInfo[out] Pointer to a buffer that, , receives a linked list of IP_ADAPTER_INFO structures.pOutBufLen[in] Pointer to a ULONG variable that specifies the size of the buffer pointed to by the pAdapterInfo parameter. If this size is insufficient to hold the adapter information, GetAdaptersInfo fills in this variable with the required size, and returns an error code of ERROR_BUFFER_OVERFLOW.Return ValuesIf the function succeeds, the return value is ERROR_SUCCESS.If the function fails, the return value is one of the following error codes.Value MeaningERROR_BUFFER_OVERFLOW The buffer size indicated by the pOutBufLen parameter is too small to hold the adapter information. The pOutBufLen parameter points to the required size.ERROR_INVALID_PARAMETER The pOutBufLen parameter is NULL, or the calling process does not have read/write access to the memory pointed to by pOutBufLen, or the calling process does not have write access to the memory pointed to by the pAdapterInfo parameter.ERROR_NO_DATA No adapter information exists for the local computer.ERROR_NOT_SUPPORTED GetAdaptersInfo is not supported by the operating system running on the local computer.Other If the function fails, use FormatMessage to obtain the message string for the returned error.
