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ip

try

{

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);

}
