I'm having a problem with this verification of the internet connection. See I have this verification in my code:

  if (CrossConnectivity.Current.IsConnected)

  {

     ...

  }

It works, but I think there is a situation that this do not cover, I have a shopping right next door to my office, I enter the shopping and the device just connects with the shopping WI-FI, but it's not passing data, because it need's to login in the session to get free WI-FI from the shopping.

So my question in resume is, is there a way, not only to verify if the device is conected to the internet, but if it is passing data through the connection?

I didn't try this solution but it might help you.

if (CrossConnectivity.Current.IsConnected)

{

 if (ConnectGoogle())

    {

        return true;

    }

    else

    { 

      //

    }  

}

ConnectGoogle method

public bool ConnectGoogle()

{

    try

    {

        HttpURLConnection urlc = (HttpURLConnection)(new URL("http://www.google.com").OpenConnection());

        urlc.SetRequestProperty("User-Agent", "Test");

        urlc.SetRequestProperty("Connection", "close");

        urlc.ConnectTimeout = 10000;

        urlc.Connect();

        return (urlc.ResponseCode == HttpStatus.Accepted);

    }

    catch (Exception ex)

    {

        //Log(ex.Message);

        return false;

    }

}

You could use System.Net.WebClient and test open/read an url. Also another way could be to ping a resource that is theoritically never offline. i.e. google.

Something like:

if (CrossConnectivity.Current.IsConnected)

{

    try { 

        Ping ping = new Ping();

        String host = "google.com";

        byte buffer = new byte[32];

        int timeout = 1000;

        PingOptions pingOptions = new PingOptions();

        PingReply reply = ping.Send(host, timeout, buffer, pingOptions);

        if (reply.Status == IPStatus.Success){

            // Your code here...

        }

    }

    catch (Exception) {

        return false;

    }

}

Hope it helps.

Thanks everyone, I see all answers work in my situation, but I used this method from https://jamesmontemagno.github.io/ConnectivityPlugin/PingaHost.html, you could open it or just see it down here:

 var verificaPassagemDados = await CrossConnectivity.Current.IsRemoteReachable("google.com");

Thanks @sme
