近期由于项目有须要获取本机的全部存在的网络连接名称,在网上也找了资料,有好几种方法,只是就仅仅有一种是可以达到我想要的要求

写下来给大家參考下

第一种方法:遍历注冊表来获取

void __fastcall MyGetLanAdapterName(char *szLanAdapterName)
{HKEY hKey, hSubKey, hNdiIntKey;if(RegOpenKeyEx(HKEY_LOCAL_MACHINE,"System\\CurrentControlSet\\Control\\Class\\{4D36E972-E325-11CE-BFC1-08002BE10318}",0,KEY_READ,&hKey) != ERROR_SUCCESS)return;DWORD dwIndex = 0;DWORD dwBufSize = 256;DWORD dwDataType;char szSubKey[256];unsigned char szData[256];while(RegEnumKeyEx(hKey, dwIndex++, szSubKey, &dwBufSize, NULL, NULL, NULL, NULL) == ERROR_SUCCESS){if(RegOpenKeyEx(hKey, szSubKey, 0, KEY_READ, &hSubKey) == ERROR_SUCCESS){if(RegOpenKeyEx(hSubKey, "Ndi\\Interfaces", 0, KEY_READ, &hNdiIntKey) == ERROR_SUCCESS){dwBufSize = 256;if(RegQueryValueEx(hNdiIntKey, "LowerRange", 0, &dwDataType, szData, &dwBufSize) == ERROR_SUCCESS){if(strcmp((char*)szData, "ethernet") == 0) // 推断是不是以太网卡{dwBufSize = 256;if(RegQueryValueEx(hSubKey, "DriverDesc", 0, &dwDataType, szData, &dwBufSize) == ERROR_SUCCESS){// szData 中便是适配器具体描写叙述dwBufSize = 256;if(RegQueryValueEx(hSubKey, "NetCfgInstanceID", 0, &dwDataType, szData, &dwBufSize) == ERROR_SUCCESS){//szData中便是适配器名称strcpy(szLanAdapterName, (char *)szData);}}}}RegCloseKey(hNdiIntKey);}RegCloseKey(hSubKey);}dwBufSize = 256;} /* end of while */RegCloseKey(hKey);
}

szLanAdapterName即为网络连接的名称 如{C6DFC923-0895-4FCE-85F2-740E6133EC6D}

另外一种方法是通过API:

void __fastcall GetLanAdapterName()
{ULONG ulAdapterInfoSize = sizeof(IP_ADAPTER_INFO);IP_ADAPTER_INFO *pAdapterInfoBkp, *pAdapterInfo = (IP_ADAPTER_INFO*)new char[ulAdapterInfoSize];if( GetAdaptersInfo(pAdapterInfo, &ulAdapterInfoSize) == ERROR_BUFFER_OVERFLOW ) // 缓冲区不够大{delete pAdapterInfo;pAdapterInfo = (IP_ADAPTER_INFO*)new char[ulAdapterInfoSize];pAdapterInfoBkp = pAdapterInfo;}if( GetAdaptersInfo(pAdapterInfo, &ulAdapterInfoSize) == ERROR_SUCCESS ){do{ // 遍历全部适配器if(pAdapterInfo->Type == MIB_IF_TYPE_ETHERNET) // 推断是否为以太网接口{// pAdapterInfo->Description 是适配器描写叙述// pAdapterInfo->AdapterName 是适配器名称}pAdapterInfo = pAdapterInfo->Next;}while(pAdapterInfo);}delete pAdapterInfoBkp;
}

AdapterName 也能得到网络连接的名称 如{C6DFC923-0895-4FCE-85F2-740E6133EC6D} 适配器描写叙述如：Realtek RTL8139(A) PCI Fast Ethernet Adapter

第三种方法也是使用API:

void __fastcall GetLanAdapterName()
{   HANDLE   hMprConfig;DWORD   dwRet=0;CString   strInfo,strTmp;PIP_INTERFACE_INFO   plfTable=NULL;IP_ADAPTER_INDEX_MAP   AdaptMap;DWORD   dwBufferSize=0;WCHAR   szFriendName[256];DWORD   tchSize=sizeof(WCHAR)*256;ZeroMemory(&szFriendName,tchSize);dwRet=MprConfigServerConnect   (NULL,&hMprConfig);dwRet=GetInterfaceInfo(NULL,&dwBufferSize);if(dwRet == ERROR_INSUFFICIENT_BUFFER){plfTable=(PIP_INTERFACE_INFO)HeapAlloc(GetProcessHeap(),HEAP_ZERO_MEMORY,dwBufferSize);GetInterfaceInfo(plfTable,&dwBufferSize);}strInfo.Empty();for(UINT   i=0;i<plfTable->NumAdapters;i++){AdaptMap=plfTable->Adapter[i];dwRet=MprConfigGetFriendlyName(hMprConfig,AdaptMap.Name,(PWCHAR)szFriendName,tchSize);char szName[256];memset( szName, 0, 256 );int nLen = WideCharToMultiByte( CP_ACP,NULL, szFriendName,-1,NULL,0,NULL,FALSE );WideCharToMultiByte (CP_ACP,NULL,szFriendName,-1,szName,nLen,NULL,FALSE);strTmp.Format(_T("Index:%u\nName:%s\n"),AdaptMap.Index,szName);   //szName即为网络连接的名称strInfo+=strTmp;}HeapFree(GetProcessHeap(),HEAP_ZERO_MEMORY,plfTable);
}

szName即为网络连接的名称,如 "本地连接","本地连接1"...后面通过API函数获取须要增加以下头文件

#include <Mprapi.h>
#include <iphlpapi.h>
#pragma comment( lib, "Iphlpapi.lib" )
#pragma comment( lib, "Mprapi.lib" )

当然, 我须要的是获取网络连接的显示名字,所以选择第三种方法
