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

using System.Net;
using System.Text.RegularExpressions;
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

  private static string SendRequest(string url, Encoding encoding,CredentialCache cache)
  {

   if (cache != null)
   {
    request.PreAuthenticate = true;
    request.Credentials = cache;
   }
   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;
}
