Check internet connection (availability) in Windows 8

Question

How to check internet connection availability in Windows 8,C# development ? I looked at MSDN but page has been deleted.

Solution 1

I use this snippet without problems:

public static bool IsInternet()
{
    ConnectionProfile connections = NetworkInformation.GetInternetConnectionProfile();
    bool internet = connections != null && connections.GetNetworkConnectivityLevel() == NetworkConnectivityLevel.InternetAccess;
    return internet;
}

Solution 2

I had to use GetConnectionProfiles() and GetInternetConnectionProfile() to make it work across all devices.

class ConnectivityUtil
{
    internal static bool HasInternetConnection()
    {            
        var connections = NetworkInformation.GetConnectionProfiles().ToList();
        connections.Add(NetworkInformation.GetInternetConnectionProfile());

        foreach (var connection in connections)
        {
            if (connection == null)
                continue;

            if (connection.GetNetworkConnectivityLevel() == NetworkConnectivityLevel.InternetAccess)
                return true;
        }

        return false;
    }
}

Hi Martin, how can I achieve the same thing in windows phone 8? I get get "Method or operation not implemented" exception in windows phone 8 using your snippet. Thanks in advance

This does not work if there are multiple connections, which e.g. may be the case in the emulators. Use the code from Joshua Heller below, which fixes the problem.

This also works if there are multiple internet connections - which may be the case in the Win 10 emulator and other circumstances.
