Have a look at http://www.codeproject.com/KB/IP/netcfg.aspx. It's a giant example of what you want to do.
看看http://www.codeproject.com/KB/IP/netcfg.aspx。这是您想要做什么的一个很好的例子。

It sounds like you want a combination of a few different functions.
听起来您想要几个不同功能的组合。
To get a list of adapters with their IPv4 addresses/masks, associated WINS servers and DNS servers, you can use GetAdaptersInfo. To get IPv6 addresses, you can use GetAdaptersAddresses.
要获取带有 IPv4 地址/掩码、关联的 WINS 服务器和 DNS 服务器的适配器列表，您可以使用GetAdaptersInfo. 要获取 IPv6 地址，您可以使用GetAdaptersAddresses.
Depending on what is included in your "etc." you might also want GetIfTableand GetIfEntry. GetIfTablegets a list of network adapters. GetIfEntrygets you information about each. These retrieve things like the amount of data that's been transmitted/retrieved over a particular interface. There's also a GetIfTable2/GetIfEntry2that are only for Vista and newer that get more information.
取决于您的“等”中包含的内容。你可能还想要GetIfTable和GetIfEntry。GetIfTable获取网络适配器列表。GetIfEntry获取有关每个的信息。这些检索诸如通过特定接口传输/检索的数据量之类的内容。还有一个GetIfTable2/GetIfEntry2仅适用于 Vista 和更新版本，可以获取更多信息。
If memory serves, GetIfTable/GetIfEntrylist allthe interfaces in the machine. GetAdaptersInfoonly works with the "real" adapters.
如果没记错的话，GetIfTable/GetIfEntry列出机器中的所有接口。GetAdaptersInfo仅适用于“真正的”适配器。

Perversely you can use getaddrinfo ("..localmachine")to enumerate interfaces on Windows 2003+.
相反，您可以使用getaddrinfo ("..localmachine")枚举 Windows 2003+ 上的接口。

Windows 7 with Service Pack 1 (SP1) and Windows Server 2008 R2 with Service Pack 1 (SP1) add support to hide interfaces.
带有 Service Pack 1 (SP1) 的 Windows 7 和带有 Service Pack 1 (SP1) 的 Windows Server 2008 R2 添加了对隐藏界面的支持。
