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);
}
</div>
[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);
}
</div>
