Question

我在windows mobile模拟器中使用了以下功能来检查网络状态。它返回“未知”以太网是否存在。

function checkConnection() {
var networkState = navigator.network.connection.type;

var states = {};
states[Connection.UNKNOWN]  = 'Unknown connection';
states[Connection.ETHERNET] = 'Ethernet connection';
states[Connection.WIFI]     = 'WiFi connection';
states[Connection.CELL_2G]  = 'Cell 2G connection';
states[Connection.CELL_3G]  = 'Cell 3G connection';
states[Connection.CELL_4G]  = 'Cell 4G connection';
states[Connection.NONE]     = 'No network connection';

alert('Connection type: ' + states[networkState]);

}

checkConnection();

在Windows Phone上，For get当前界面可以使用“NetworkInterfaceList”类：

NetworkInterfaceInfo CurrentInterface;
var interfacesList = new NetworkInterfaceList();

foreach (NetworkInterfaceInfo specificInterface in interfacesList)
{
    CurrentInterface = specificInterface;
    break;
}

您可以订阅网络更改活动：

DeviceNetworkInformation.NetworkAvailabilityChanged += NetworkChanged;

private void NetworkChanged(object sender, NetworkNotificationEventArgs e)
{
    CurrentInterface = e.NetworkInterface;
}

获取当前界面后，您可以获得真正的网络类型：

switch (CurrentInterface.InterfaceType)
{
    case NetworkInterfaceType.Ethernet:
        // ETHERNET (USB connected)
        break;
    case NetworkInterfaceType.MobileBroadbandCdma:
        switch (pNetworkInterfaceInfo.InterfaceSubtype)
        {
            case NetworkInterfaceSubType.Cellular_GPRS:
                // 2G
                break;
            case NetworkInterfaceSubType.Cellular_EDGE:
                // 2GP
                break;
            case NetworkInterfaceSubType.Cellular_EVDO:
            case NetworkInterfaceSubType.Cellular_EVDV:
                // ?
                break;
            case NetworkInterfaceSubType.Cellular_1XRTT:
                // ?
                break;
            case NetworkInterfaceSubType.Cellular_3G:
                // 3G
                break;
            case NetworkInterfaceSubType.Cellular_HSPA:
                // 3GP
                break;
            case NetworkInterfaceSubType.Unknown:
                // Unknonwn ? 4G is Unknown.
                break;
        }
        break;
    case NetworkInterfaceType.MobileBroadbandGsm:
        switch (pNetworkInterfaceInfo.InterfaceSubtype)
        {
            case NetworkInterfaceSubType.Cellular_GPRS:
                // 2G
                break;
            case NetworkInterfaceSubType.Cellular_EDGE:
                // 2GP
                break;
            case NetworkInterfaceSubType.Cellular_EVDO:
            case NetworkInterfaceSubType.Cellular_EVDV:
                // ??
                break;
            case NetworkInterfaceSubType.Cellular_1XRTT:
                // ??
                break;
            case NetworkInterfaceSubType.Cellular_3G:
                // 3G
                break;
            case NetworkInterfaceSubType.Cellular_HSPA:
                // 3GP
                break;
            case NetworkInterfaceSubType.Unknown:
                // Unknown? 4G is Unknown
                break;
        }
        break;
    case NetworkInterfaceType.Wireless80211:
        // WIFI
        break;
}

请注意，对于Windows Phone 7项目，我们没有“4G类型”，当我用设备测试4G时，NetworkInterfaceType是未知的......但是，如果我们在32G或3G中遇到网络问题，也是未知的..

我没有使用Windows Phone 8项目进行测试，但从理论上讲，它适用于4G。

此外，您可以在网络类型here上获得更多详细信息。

PS：为了测试网络，没有比使用真实设备测试更好的了，因此，真正的网络。
