推荐答案

如果您可以用芒果（7.1）的SDK，如果你的方案涉及到使用套接字，有一个简单的方式来获得你刚才提出的连接NetworkInterfaceType /子类型的信息：

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;

没有必要使用NetworkInterface.NetworkInterfaceType属性（臭名昭著需要长达30秒返回）;没有必要以触发主机名解析刚确定网络类型;没有必要听网络更改事件。

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，这个工作最好与DeviceNetworkInformation.IsNetworkAvailable或NetworkInterface.GetIsNetworkAvailable（）一起 - 这些呼叫立即返回，无论你是在网络上还是不行。如果你是，你首先连接插座，当它连接发问： - ）

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 :-)

最后请注意：芒果的DeviceNetworkInformation.IsWiFiEnabled提防 - 我认为这将返回是否我是一个WiFi网络上，而是它返回的wifi是否在手机设置中开启或关闭...不是超级有用。

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.
