Verify not only internet connection but if it is passing data - XAMARIN

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?

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

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.

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;
    }
}
