用C#编写获取远程IP,MAC的方法-.NET教程,C#语言

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);

}
