Windows 10 UWP - 检测当前的Internet连接是Wifi还是Cellular？

Question

在Windows 10 UWP应用中，如何检测当前的互联网连接是Wifi还是Cellular？

Answer 1

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

一个例子是：

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

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

我希望这会有所帮助。

除了获得连接（其他人提到的连接）之外，您还可以更好地处理计量连接。

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;
}

请参阅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";
}
