用C#編寫獲取遠程IP,MAC的方法

如果要想獲得遠程的地址，需要用sendarp這個函數來實現。具體的代碼如下：
[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);
}
