C# 窗口和捕获门户

尝试检测internet连接（即连接到咖啡店的笔记本电脑）上的捕获门户何时正在使用

尝试使用网络列表管理器COM对象实现此目标：

NETWORKLIST.NetworkListManager _networkListManager = new NetworkListManager();
foreach (INetworkConnection net in _networkListManager.GetNetworkConnections())
{                
    if (net.GetConnectivity().HasFlag(NLM_CONNECTIVITY.NLM_CONNECTIVITY_IPV4_INTERNET) == true)
      {
           // Check if we are connected by a captive web portal
           // using NLM_INTERNET_CONNECTIVITY_WEBHIJACK
      }                                
 }

根据此处的文档：

“可以通过使用INetwork或INetworkConnection接口的IPropertyBag接口查询NA_InternetConnectionyV4或NA_InternetConnectionyV6属性来检索这些连接标志”

我发现NA_InternetConnectionyV4枚举不存在（实现不完整），或者我不知道如何使用它们

---

是否有人实际使用过此方法，或者对检测捕获门户何时正在使用的方法有什么想法？

关闭此方法，调查显示NA_InternetConnectionyV4枚举不存在，MSDN文档不正确。

这不是C，但我发现这些API在C上工作++

pNetworkListManager->GetNetworks（NLM_ENUM_NETWORK_CONNECTED，&pEnum） 细木工*pINetwork

//Should actually loop through the possible networks.
HRESULT hr = pEnum->Next(1, &pINetwork, nullptr);

IPropertyBag *pNetworkPropertyBag;
HRESULT hrQueryInterface = pINetwork->QueryInterface(IID_IPropertyBag, (LPVOID*)&pNetworkPropertyBag);
if (SUCCEEDED(hrQueryInterface 1) && pNetworkPropertyBag != nullptr)
{
    NLM_CONNECTIVITY networkConnectivity;
    VARIANT variantConnectivity;

    if (SUCCEEDED(pINetwork->GetConnectivity(&networkConnectivity)))
    {
        if ((networkConnectivity & 
        NLM_CONNECTIVITY_IPV4_INTERNET) == NLM_CONNECTIVITY_IPV4_INTERNET)
        {
            VariantInit(&variantConnectivity);
            if (SUCCEEDED(pNetworkPropertyBag->Read(NA_InternetConnectivityV4, &variantConnectivity, nullptr)) && (V_UINT(&variantConnectivity) & NLM_INTERNET_CONNECTIVITY_WEBHIJACK) == NLM_INTERNET_CONNECTIVITY_WEBHIJACK)
            {
                //Captive Portal detected
            }

    }
}
