Windows 10 UWP - 檢測當前的互聯網連接是Wifi還是蜂窩？

Question

在Windows 10 UWP應用程序中，如何檢測當前的Internet連接是Wifi還是Cellular？

Answer 1

在UWP中，您可以使用IsWlanConnectionProfile或IsWwanConnectionProfile屬性檢查網絡連接。

一個例子是：

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

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

我希望這有助於。

Answer 2

除了獲得連通性（其他人已經提到）之外，您還可以更好地處理計量連接。

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; 
}

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"; 
}
