易语言 取mac地址

易语言是一种编程语言，通过易语言可以方便地编写一些小型的应用程序。要在易语言中取得MAC地址，可以使用WinAPI中的一些函数来实现。

首先，可以使用GetAdaptersInfo函数来获取所有网络适配器的信息。这个函数的原型是：

Declare Function GetAdaptersInfo Lib "iphlpapi.dll" (pAdapterInfo As Any, pOutBufLen As Long) As Long

其中，pAdapterInfo参数是一个指向一个适配器信息结构体的指针。可以定义一个结构体来存储适配器信息，如下：

Type _IP_ADAPTER_INFO
Next As Long
ComboIndex As Long
AdapterName As String * MAX_ADAPTER_NAME_LENGTH
Description As String * MAX_ADAPTER_DESCRIPTION_LENGTH
AddressLength As Long
Address(MAX_ADAPTER_ADDRESS_LENGTH - 1) As Byte
Index As Long
Type As Long
DhcpEnabled As Long
CurrentIpAddress As Any
IpAddressList As _IP_ADDR_STRING
GatewayList As _IP_ADDR_STRING
DhcpServer As _IP_ADDR_STRING
HaveWins As Long
PrimaryWinsServer As _IP_ADDR_STRING
SecondaryWinsServer As _IP_ADDR_STRING
LeaseObtained As Long
LeaseExpires As Long
End Type

其中，Address是一个存储MAC地址的字节数组。

然后，可以调用GetAdaptersInfo函数来获取适配器信息，这样就可以得到其中的MAC地址。需要注意的是，要先通过调用GetAdaptersInfo函数并传入一个NULL指针来获取所需的缓冲区大小，然后再分配足够的内存来存储适配器信息。

具体的实现代码如下：

Dim AdapterInfo As _IP_ADAPTER_INFO
Dim OutBufLen As Long
Dim Ret As Long

OutBufLen = 0
Ret = GetAdaptersInfo(0, OutBufLen)
If Ret = ERROR_BUFFER_OVERFLOW Then
Dim BufferPtr As Long
BufferPtr = HeapAlloc(GetProcessHeap(), HEAP_ZERO_MEMORY, OutBufLen)
If BufferPtr <> 0 Then
Ret = GetAdaptersInfo(BufferPtr, OutBufLen)
If Ret = NO_ERROR Then
Dim AdapterPtr As Long
Dim AdapterCount As Long
AdapterPtr = BufferPtr
Do While AdapterPtr <> 0
CopyMemory AdapterInfo, ByVal AdapterPtr, Len(AdapterInfo)
' 可以在这里操作AdapterInfo中的MAC地址
AdapterPtr = AdapterInfo.Next
Loop
End If
HeapFree GetProcessHeap(), 0, BufferPtr
End If
End If

以上是在易语言中取得MAC地址的基本方法，具体的实现还需要根据实际情况进行调整和完善。
