有没有DELPHI的源码？

// Fetches the MAC address and prints it
static void GetMACaddress(void)
{
IP_ADAPTER_INFO AdapterInfo[16]; // Allocate information
// for up to 16 NICs
DWORD dwBufLen = sizeof(AdapterInfo); // Save memory size of buffer

DWORD dwStatus = GetAdaptersInfo( // Call GetAdapterInfo
AdapterInfo, // [out] buffer to receive data
&dwBufLen); // [in] size of receive data buffer
assert(dwStatus == ERROR_SUCCESS); // Verify return value is
// valid, no buffer overflow

PIP_ADAPTER_INFO pAdapterInfo = AdapterInfo; // Contains pointer to
// current adapter info
do {
PrintMACaddress(pAdapterInfo->Address); // Print MAC address
pAdapterInfo = pAdapterInfo->Next; // Progress through
// linked list
}
while(pAdapterInfo); // Terminate if last adapter
}

具体函数查MSDN和PSDK

这个论坛随便搜索一下就有了。这个算法太常见了。下面就是抄来的。
type
