Windows 10 UWP - 检测当前互联网连接是 Wifi 还是蜂窝网络？

Question

在 Windows 10 UWP 应用程序中，我如何检测当前的互联网连接是 Wifi 还是蜂窝网络？

Answer 1

在 UWP 中，您可以使用 IsWlanConnectionProfile 或 IsWwanConnectionProfile 属性检查网络连接。

例如：

var temp = Windows.Networking.Connectivity.NetworkInformation.GetInternetConnectionProfile();

if (temp.IsWlanConnectionProfile)
{
     // its wireless
}else if (temp.IsWwanConnectionProfile)
{
     // its mobile
}

希望对您有所帮助。

除了获得连接（其他人提到的）之外，您还可以更好地处理按流量计费的连接。

How to manage metered network cost constraints

switch (connectionCost.NetworkCostType)
{
    case NetworkCostType.Unrestricted:
        //
        break;
    case NetworkCostType.Fixed:
        //
        break;
    case NetworkCostType.Variable:
        //
        break;
    case NetworkCostType.Unknown:
        //
        break;
    default:
        //
        break;
}

参见networking demo at GitHub。

if (connectionCost.Roaming || connectionCost.OverDataLimit)
{
    Cost = NetworkCost.OptIn;
    Reason = connectionCost.Roaming
        ? "Connection is roaming; using the connection may result in additional charge."
        : "Connection has exceeded the usage cap limit.";
}
else if (connectionCost.NetworkCostType == NetworkCostType.Fixed
    || connectionCost.NetworkCostType == NetworkCostType.Variable)
{
    Cost = NetworkCost.Conservative;
    Reason = connectionCost.NetworkCostType == NetworkCostType.Fixed
        ? "Connection has limited allowed usage."
        : "Connection is charged based on usage. ";
}
else
{
    Cost = NetworkCost.Normal;
    Reason = connectionCost.NetworkCostType == NetworkCostType.Unknown
        ? "Connection is unknown"
        : "Connection cost is unrestricted";
}
