如何在windows phone 7中检查互联网是否可用？

Question

为了上网检查，我写了以下几行代码。

bool isAvailable = NetworkInterface.GetIsNetworkAvailable();
             if (isAvailable == true)
             {
}

如果net不可用，上面的行总是返回true also.please告诉我如何检查internet连接？

Answer 1

检查NetworkInterfaceType.如果互联网可用，则它应该不是None

return (Microsoft.Phone.Net.NetworkInformation.NetworkInterface.NetworkInterfaceType 
!= Microsoft.Phone.Net.NetworkInformation.NetworkInterfaceType.None);

希望这能有所帮助。

Answer 2

你也可以试试，

bool isAvailable = Microsoft.Phone.Net.NetworkInformation.DeviceNetworkInformation.IsNetworkAvailable;

Answer 3

     Always check this in a thread, it takes some time        
    internal static bool IsNetworkAvailable()
    {
        bool _bhasNetworkConnection = false;
        try
        {
            _bhasNetworkConnection = (NetworkInterface.NetworkInterfaceType != NetworkInterfaceType.None);
        }
        catch
        {
            _bhasNetworkConnection = false;
        }

        return _bhasNetworkConnection;
    }
