       [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();
