c#獲取遠程ip地址

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 .net_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]);
