Check if I have a Internet connection

Question

Hello everybody,
I need to check if a internet connection exists because the little program i wrote download a file from a server.
I found a example but this isn't working?!

 bool checkInternet = new Ping().Send("google.com", 500).Status == IPStatus.Success;

if (checkInternet == false)
            {
                MessageBoxButton button = MessageBoxButton.OK;
                string caption = "Internet Error";
                MessageBox.Show("Bitte Internetverbindung überprüfen und erneut versuchen.", caption, button);
            }

Does anybody know how I can solve the problem?

Answer 1

Maybe start downloading the file and intercept the errors, including the ones related to connection.

The result of checking connection is not necessarily valid after the check.
