Answer 1

试试这个；

1-将这些命名空间添加到项目中；

使用System.Net.Mail；

    MailMessage mail = new MailMessage();
    mail.IsBodyHtml = true;
    mail.To.Add(UserName.Text.ToString());

    mail.From = new MailAddress("[e-mail]", "Hello", System.Text.Encoding.UTF8);
    mail.Subject = "Verification Code";
    string Mesaj = "Hello";
    mail.Body = Mesaj;

    SmtpClient smtp = new SmtpClient();
    smtp.Credentials = new NetworkCredential("[e-mail]", "shammus123");
    smtp.Port = 587;
    smtp.Host = "smtp.gmail.com";
    smtp.EnableSsl = true;
    if (UserName.Text.ToString() != string.Empty)
    {
        smtp.Send(mail);
    }
