如果要想获得远程的地址，需要用sendarp这个函数来实现。具体的代码如下：[DllImport("Iphlpapi.dll")]private static unsafe extern int SendARP(Int32 dest,Int32 host,ref IntPtr mac,ref IntPtr length);[DllImport("Ws2_32.dll")]private static extern Int32 inet_addr(string ip);Int32 ldest= inet_addr("157.60.68.163");//目的地的ipInt32 lhost= inet_addr("157.60.68.33");//本地的iptry{Byte[] macinfo=new Byte[6];Int32 length=6;IntPtr mac=new IntPtr(macinfo[0]);IntPtr len=new IntPtr(6);int ii=SendARP(ldest,lhost, ref mac, ref len);Console.WriteLine("Mac Add:"+mac);Console.WriteLine("length:"+len);}catch(Exception err){Console.WriteLine(err);}
