Question

Is it possible to make a windows service from a console application.
In fact, i made a console application that sends emails to persons from a database but when I tried to make a service with almost the same code it didn’t work. After installing it emails aren’t nomore sent. So, I want to transform my console application into a service if there is a way because I want to send them automatically and I don’t want to use task sheduler.

Here is my console application main

     {
        MailMessage mail = new MailMessage();
        mail.From = new MailAddress(ConfigurationManager.AppSettings["email"]);
        mail.Subject = "Rappel délai tâche";
        SmtpClient client = new SmtpClient(ConfigurationManager.AppSettings["domaine"]);
        client.EnableSsl = true;

        client.Credentials = new NetworkCredential(ConfigurationManager.AppSettings["email"], ConfigurationManager.AppSettings["password"]); 

        BDGestionEntities bd = new BDGestionEntities();
        TimeSpan diff;
        DateTime aujourdhui = DateTime.Today;
        List <tache> taches = bd.taches.ToList();

        foreach (var k in taches)
        {
            Console.WriteLine(k.nom_tache);
            diff = k.date_fin.Subtract(aujourdhui);
            int datediff = Convert.ToInt32(diff.TotalDays);
            if (datediff <= 2)
            {



                mail.To.Add(k.utilisateur.email);

                mail.Body = "Bonjour, " + k.utilisateur.nom + " " + k.utilisateur.prenom +
                    "\n\nNous vous envoyons le présent mail pour vous rappeler que la tâche \"" + k.nom_tache + "\" qui vous est accordée touchera à sa fin d'ici deux jours.\nVeuillez respecter le délai. \n\n Bien cordialement.";
                try
                {
                    client.Send(mail);
                    Console.WriteLine("Email envoyé");
                }
                catch (Exception ex)
                {
                    Console.Write(ex.Message);
                }
            }
        }
    }

In fact I’m using a model with ado .net inorder to access to my database

Answer 1

I found the solution for that. In fact, it was just a connection problem and all I had to do was to add permissions to the service in order to let it access the database. Thank you everyone.
