C#获取路由器外网IP，MAC地址的实现代码

c#实现的获取路由器mac地址，路由器外网地址。对于要获取路由器mac地址，一定需要知道路由器web管理系统的用户名和密码。至于获取路由器的外网ip地址，可以不需要知道路由器web管理系统的用户名和密码，但是需要有一个代理页面获取客户端公网ip地址的，这样c#请求此页面即可获取到路由器公网ip地址。如

//getip.ashx

测试路由为水星 mr804，水星 mr808，都可以成功重启路由和获取到路由器mac和外网ip地址

源代码

using system.io;
public class router
{
  encoding gb2312 = encoding.getencoding(936);//路由器的web管理系统默认编码为gb2312

   }
   string html = null;
   try
   {
    httpwebresponse response = (httpwebresponse)request.getresponse();
    streamreader srd = new streamreader(response.getresponsestream(), encoding);
    html = srd.readtoend();
    srd.close();
    response.close();
   }
   catch (exception ex) { html = "false" + ex.message; }
   return html;

mfc 获取外网ip地址和mac地址

ip地址获取：

cstring getsystemip(void) 
{ 
 cstring cssource; 
 cstring csaddress; 
 cstring csipaddress; 
 csipaddress.format(_t(" ")); 
 cinternetsession mysession(null,0); 
 chttpfile* myhttpfile=null; 
 csaddress=_t("http://iframe.ip138.com/ic.asp");//ip138网页 http://www.ip138.com/ip2city.asp 
 myhttpfile=(chttpfile*)mysession.openurl(csaddress);//读取网络地址 
 while(myhttpfile->readstring(cssource)) 
 { //循环读取下载来的网页文本 
  //code 转换 
  char *pstr = (char*)cssource.getbuffer(cssource.getlength()); //取得str对象的原始字符串 
  int nbuffersize = multibytetowidechar(cp_utf8, 0,pstr, -1, null, 0); //取得所需缓存的多少 
  wchar_t *pbuffer = (wchar_t*)malloc(nbuffersize * sizeof(wchar_t));//申请缓存空间 
  multibytetowidechar(cp_utf8, 0, pstr, -1 , pbuffer, nbuffersize*sizeof(wchar_t));//转码 
  //messagebox(pbuffer); //显示 
  cssource.format(_t("%s"),pbuffer); 
  free(pbuffer); //释放缓存 
 
  int begin=0; 
  begin=cssource.find(_t("["),0); 
  if(begin!=-1)//如果找到"["， 则找"]" 中括号内的文本则是 你的外网ip 
  { 
   int end=cssource.find(_t("]")); 
   csipaddress.format(_t("%s"),cssource.mid(begin+1,end-begin-1));//提取外网ip 
   return csipaddress; 
  } 
 } 
 return csipaddress; 
} 

mac地址获取：

cstring getmacaddress(void) 
{ 
 //cstring strip,strgateway,strsubnetmask; 
 cstring strmac; 
 strmac.format(_t("")); 
 u_char pmac[6]; 
 pip_adapter_info adp = null; 
 ulong ulong=0; 
 //为适配器申请内存 
 ::getadaptersinfo(adp,&ulong); 
 adp = (pip_adapter_info)::globalalloc(gptr,ulong); 
 
 //取得本地适配器结构信息 
 if(::getadaptersinfo(adp,&ulong) == error_success) 
 { 
  if(adp != null) 
  { 
   //strmacadd.format("%s",adp->address); 
   memcpy(pmac,adp->address,6); 
   strmac.format(_t("%02x-%02x-%02x-%02x-%02x-%02x"),pmac[0],pmac[1],pmac[2],pmac[3],pmac[4],pmac[5]); 
   //strgateway.format(_t("%s"),adp->gatewaylist.ipaddress.string);// 网关 
   //strip.format(_t("%s"),adp->ipaddresslist.ipaddress.string);//ip 
   //strsubnetmask.format(_t("%s"),adp->ipaddresslist.ipmask.string);//子网掩码 
   //messagebox(strmac); 
  } 
 } 
 return strmac; 
}
