推荐答案

如果您可以使用 Mango (7.1) SDK，并且如果您的场景涉及使用套接字，则有一种简单的方法可以获取连接的 NetworkInterfaceType/SubType 信息你刚刚做了:

If you can use the Mango (7.1) SDK, and if your scenario involves using sockets, there's a trivial way to get the NetworkInterfaceType/SubType information for the connection you just made:

    NetworkInterfaceInfo netInterfaceInfo = socket.GetCurrentNetworkInterface();
    var type = netInterfaceInfo.InterfaceType;
    var subType = netInterfaceInfo.InterfaceSubtype;

无需使用 NetworkInterface.NetworkInterfaceType 属性(众所周知，该属性需要 30 秒才能返回)；无需为了确定网络类型而触发主机名解析；无需监听网络变化事件.

No need to use the NetworkInterface.NetworkInterfaceType property (which notoriously takes up to 30sec to return); no need to trigger a hostname resolution just to determine the network type; no need to listen to network change events.

当然，这与 DeviceNetworkInformation.IsNetworkAvailable 或 NetworkInterface.GetIsNetworkAvailable() 结合使用效果最佳 - 无论您是否在网络上，这些调用都会立即返回.如果是，请先连接套接字并在连接时提问:-)

Of course, this works best in conjunction with DeviceNetworkInformation.IsNetworkAvailable or NetworkInterface.GetIsNetworkAvailable() - those calls return immediately whether you're on a network or not. If you are, you connect the socket first and ask questions when it's connected :-)

最后一点:当心 Mango 的 DeviceNetworkInformation.IsWiFiEnabled - 我以为它会返回我是否在 wifi 网络上，但它会返回手机设置中是否打开或关闭 wifi ......不是很有用.

A final note: beware of Mango's DeviceNetworkInformation.IsWiFiEnabled - I thought it would return whether I was on a wifi network, but instead it returns whether wifi is turned on or off in the phone settings... not super useful.
