I think you already discovered the answer yourself, but I will keep posting the answer instead.

In case you are using Windows Forms and not Windows Presentation Forms (The different only the design part and many new features that does not have on Windows Forms), what I have done is like this (to send email):

public void SendEmail(string _from, string _fromDisplayName, string _to, string _toDisplayName, string _subject, string _body, string _password)
    {
        try
        {
            SmtpClient _smtp = new SmtpClient();

            MailMessage _message = new MailMessage();

            _message.From = new MailAddress(_from, _fromDisplayName); // Your email address and your full name

            _message.To.Add(new MailAddress(_to, _toDisplayName)); // The recipient email address and the recipient full name // Cannot be edited

            _message.Subject = _subject; // The subject of the email
            _message.Body = _body; // The body of the email

            _smtp.Port = 587; // Google mail port
            _smtp.Host = "smtp.gmail.com"; // Google mail address
            _smtp.EnableSsl = true;
            _smtp.UseDefaultCredentials = false;
            _smtp.Credentials = new NetworkCredential(_from, _password); // Login the gmail using your email address and password

            _smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
            _smtp.Send(_message);

            ShowMessageBox("Your message has been successfully sent.", "Success", 2);
        }

        catch (Exception ex)
        {
            ShowMessageBox("Message : " + ex.Message + "\n\nEither your e-mail or password incorrect. (Are you using Gmail account?)", "Error", 1);
        }
    }

And I am using it like this:

SendEmail(textBox2.Text, textBox5.Text, textBox3.Text, "YOUR_FULL_NAME", textBox4.Text, textBox6.Text, "YOUR_EMAIL_PASSWORD");

May this answer would help you.
