Question

SMTP和计时是否存在已知问题？我在下面添加了一些代码，基本上会向某人发送生日问候，还有一个星座运势和其他分享生日的人（为了好玩）。

我使用Regex替换来从其他方法获取元素，星座和其他人，并将它们插入到一对“p”标记之间的HTML文档中。我很肯定这些方法是有效的，我很肯定HTML文档正在被重新格式化（根据控制台，它在我的另一个测试中打印出我的新HTML文档）。我想也许我的问题是电子邮件是在更换有机会发生之前被发送的，但我很容易被基地拒之门外。如果有人之前有过这个问题或者知道它的原因，我会非常感激。 TIA。

public void formatHTMLTest()



    { using (StreamReader reader = File.OpenText("../../BirthdayMessage.htm"))

        {
            //Format the body
            //Format the Famous People
            string html = reader.ReadToEnd();

            string replacePattern1 = "<!--INJECT FAMOUS PEOPLE HERE-->";
            List<string> famousPeople = new List<string>();

            famousPeople.Add("test1");
            famousPeople.Add("test2");
            famousPeople.Add("test3");

            StringBuilder famousSB = new StringBuilder();
            foreach (string person in famousPeople)
            {
                famousSB.Append(person + ", ");
            }
            int length = famousSB.Length;

            famousSB.Remove(length - 2, 2);
            string famousString = famousSB.ToString();

            string html1 = Regex.Replace(html, replacePattern1, famousString);
            //Format the Horoscope
            string horoscope = "FOO.";

            string replacePattern2 = "<!--INJECT HOROSCOPE HERE-->";
            string html2 = Regex.Replace(html1, replacePattern2, horoscope);


            //Configuring the SMTP client
            SmtpClient smtp = new SmtpClient();
            smtp.Port = 25;
            smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
            smtp.UseDefaultCredentials = false;
            smtp.Credentials = new NetworkCredential("barfoo@sender.com", "senderPass");
            smtp.Host = "mysmtp";

            //Set up email that is sent to the client
            MailMessage clientEmail = new MailMessage();
            clientEmail.From = new System.Net.Mail.MailAddress("barfoo@sender.com");
            clientEmail.To.Add(new MailAddress("foobar@recipient.com"));
            clientEmail.Subject = "Happy Birthday!";
            clientEmail.IsBodyHtml = true;
            clientEmail.Body = html;

            //using (smtp as IDisposable)
            {
                smtp.Send(clientEmail);
                clientEmail.Dispose();
            }
        }
    }

{ using (StreamReader reader = File.OpenText("../../BirthdayMessage.htm")) { //Format the body //Format the Famous People string html = reader.ReadToEnd(); string replacePattern1 = ""; List<string> famousPeople = new List<string>(); famousPeople.Add("test1"); famousPeople.Add("test2"); famousPeople.Add("test3"); StringBuilder famousSB = new StringBuilder(); foreach (string person in famousPeople) { famousSB.Append(person + ", "); } int length = famousSB.Length; famousSB.Remove(length - 2, 2); string famousString = famousSB.ToString(); string html1 = Regex.Replace(html, replacePattern1, famousString); //Format the Horoscope string horoscope = "FOO."; string replacePattern2 = ""; string html2 = Regex.Replace(html1, replacePattern2, horoscope); //Configuring the SMTP client SmtpClient smtp = new SmtpClient(); smtp.Port = 25; smtp.DeliveryMethod = SmtpDeliveryMethod.Network; smtp.UseDefaultCredentials = false; smtp.Credentials = new NetworkCredential("barfoo@sender.com", "senderPass"); smtp.Host = "mysmtp"; //Set up email that is sent to the client MailMessage clientEmail = new MailMessage(); clientEmail.From = new System.Net.Mail.MailAddress("barfoo@sender.com"); clientEmail.To.Add(new MailAddress("foobar@recipient.com")); clientEmail.Subject = "Happy Birthday!"; clientEmail.IsBodyHtml = true; clientEmail.Body = html; //using (smtp as IDisposable) { smtp.Send(clientEmail); clientEmail.Dispose(); } } }

我想这是不言而喻的，因为我能收到一封电子邮件，但为了清楚起见，SMTP也没有问题。我完全能够收到电子邮件。问题是它们不包含我的控制台中出现的替换html用于其他测试。

此外，您在此代码中看到的任何其他问题（优化等）都会毫不犹豫地发表评论。我总是愿意学习！感谢

Answer 1

您正在将字符串html注入正文。它应该是html2？

Html电子邮件的更新速度不够快，无法用于smtp
