public class Win32 {
[DllImport("Iphlpapi.dll")]
public static extern int SendARP(Int32 dest,Int32 host,ref IntPtr mac,ref IntPtr length);
[DllImport("Ws2_32.dll")]
public static extern Int32 inet_addr(string ip);
}//调用dll的类

void mac()
{
Int32 ldest= Win32.inet_addr(Request.UserHostAddress);//目的地的ip
Int32 lhost=Win32.inet_addr("190.10.51.5");//本地的ip


try
{
Byte[] macinfo=new Byte[6];
Int32 length=6;

IntPtr mac=new IntPtr(macinfo[0]);
IntPtr len=new IntPtr(6);
int ii=Win32.SendARP(ldest,lhost, ref mac, ref len);


ip+="**mac地址："+mac.ToString();


}
catch(Exception err)
{
ip+="";
}
}//mac
