win com类和接口说明

1. INetworkListManager

INetworkListManager 接口提供了一组用于执行网络列表管理功能的方法。

[通过com组件获取系统网卡] INetworkListManager接口

INetworkListManager：：ClearSimulatedProfileInfo 清除以前通过 SetSimulatedProfileInfo 应用于 Internet 连接配置文件的连接配置文件值。下一个 Internet 连接查询（通过 GetInternetConnectionProfile）将使用系统信息。
INetworkListManager：：get_IsConnected get_IsConnected 属性指定本地计算机是否具有网络连接。
INetworkListManager：：get_IsConnectedToInternet get_IsConnectedToInternet 属性指定本地计算机是否具有 Internet 连接。
INetworkListManager：：GetConnectivity GetConnectivity 方法返回计算机的整体连接状态。
INetworkListManager：：GetNetwork GetNetwork 方法基于提供的网络 ID 检索网络。
INetworkListManager：：GetNetworkConnection GetNetworkConnection 方法基于提供的网络连接 ID 检索网络。
INetworkListManager：：GetNetworkConnections GetNetworkConnections 方法枚举已建立的网络连接的完整列表。
INetworkListManager：：GetNetworks GetNetworks 方法检索本地计算机上可用的网络列表。
INetworkListManager：：SetSimulatedProfileInfo SetSimulatedProfileInfo 方法将一组特定的连接配置文件值应用于 Internet 连接配置文件，以支持特定按流量计费的 Internet 连接条件模拟。

使用参考：

...
IUnknown* pUnknown = NULL;
HRESULT Result = CoCreateInstance(CLSID_NetworkListManager, NULL, CLSCTX_ALL, IID_IUnknown, (void**)&pUnknown);
if (SUCCEEDED(Result))
{
    INetworkListManager* pNetworkListManager = NULL;
    Result = pUnknown->QueryInterface(IID_INetworkListManager, (void**)&pNetworkListManager);
    if (SUCCEEDED(Result))
    {
        
    }
...

2. INetConnectionManager

3. IConnectionPointContainer

支持可连接对象的连接点。

IConnectionPointContainer：：EnumConnectionPoints 创建枚举器对象以循环访问可连接对象中支持的所有连接点，每个传出 IID 一个连接点。
IConnectionPointContainer：：FindConnectionPoint 如果 IID 描述支持的传出接口，则返回指向指定 IID 的连接点的 IConnectionPoint 接口的指针。

使用参考：

...
IConnectionPointContainer* pCPContainer = NULL;
Result = pNetworkListManager->QueryInterface(IID_IConnectionPointContainer, (void**)&pCPContainer);
if (SUCCEEDED(Result))
{
    IConnectionPoint* pConnectPoint = NULL;
    Result = pCPContainer->FindConnectionPoint(IID_INetworkListManagerEvents, &pConnectPoint); // 查找 IID 对应的连接点
    if (SUCCEEDED(Result))
    {
        
    }
}
...

4. IConnectionPoint

支持可连接对象的连接点。通过 IConnectionPointContainer::FindConnectionPoint 获取。通过其函数 Advise 可以建立连接点对象与客户端接收器之间的连接。也就是可以通过此接口实现网络事件的监控。

第一个参数参考 netListmgr.h

使用参考：

...
IConnectionPoint* pConnectPoint = NULL;
Result = pCPContainer->FindConnectionPoint(IID_INetworkListManagerEvents, &pConnectPoint);
if (SUCCEEDED(Result))
{
    DWORD Cookie = NULL;

    CNetworkMonitor networkMonitor;
    std::function<void(bool)> monitorFunc = std::bind(&CNetworkMonitor::NetworkStatusChangedCallback, networkMonitor, std::placeholders::_1);
    // CNetworkListManagerEvent 为继承自 INetworkListManagerEvents 的类，重载了 ConnectivityChanged 函数
    CNetworkListManagerEvent* pNetEvent = new(std::nothrow) CNetworkListManagerEvent(monitorFunc);
    if (pNetEvent)
    {
        Result = pConnectPoint->Advise((IUnknown*)pNetEvent, &Cookie);
        ...

5. INetConnection
