用C#编写获取远程IP,MAC的方法

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ip
 Int32 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);
 }
