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); <
