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")]
privatestaticunsafeexternintSendARP(Int32dest,Int32host,refIntPtrmac,refIntPtrlength);
[DllImport("Ws2_32.dll")]
privatestaticexternInt32inet_addr(stringip);

Int32ldest=inet_addr("157.60.68.163");//目的地的ip
Int32lhost=inet_addr("157.60.68.33");//本地的ip

try
{
Byte[]macinfo=newByte[6];
Int32length=6;

IntPtrmac=newIntPtr(macinfo[0]);
IntPtrlen=newIntPtr(6);
intii=SendARP(ldest,lhost,refmac,reflen);

Console.WriteLine("MacAdd:"+mac);
Console.WriteLine("length:"+len);


}
catch(Exceptionerr)
{
Console.WriteLine(err);
}
