错误：无法从“字符串”转换到“MimeKit.MimeMessage”

Question

我想发送电子邮件，

        public readonly IMjmlServices _mjmlServices;
            bodyBuilder.HtmlBody += $"</tr></ mj - table ></ mj - column ></ mj - section ></ mj - body ></ mjml >";
            bodyBuilder.TextBody += $"This is some plain text";
            var result = _mjmlServices.Render(bodyBuilder.HtmlBody).Result;
            SmtpClient client = new SmtpClient();
                try
                {
                    client.Connect("Smtp.gmail.com", 465, true);
                    client.Authenticate("", "");
                    client.Send(result.Html);
                    Console.WriteLine("----- EMAIL SENT!! -----");
                }

但在 client.Send(result.Html); 处出现错误，指出错误：无法从“string”转换为“MimeKit.MimeMessage” 就像

如何将此字符串转换为MimeKit.MimeMessage然后将其发送为 电子邮件？

“如何将此字符串转换为 MimeKit.MimeMessage，然后将其作为电子邮件发送”

我认为您尝试使用 SmtpClient 发送电子邮件的方式不是
正确的。使用 IMjmlServices 您应该尝试以下方式：

MjmlEmailService:

 public readonly IMjmlServices _mjmlServices;
 public EmailController(IMjmlServices _mjml) => (_mjmlServices) = (_mjml);


 public async Task MjmlEmailService()
        {
            var prehtml = "<mjml><mj-body><mj-container><mj-section><mj-column><mj-text>Hello From MJML Service!</mj-text></mj-column></mj-section></mj-container></mj-body></mjml>";
            var result = await _mjmlServices.Render(prehtml);
            SmtpEmailProcessor(result.Html);
        }

注意：这里您必须从MjmlResponse接口传递result.Html，该接口将是电子邮件正文，而SMTP 请求已发送。这里最好将两个服务分开，因为 MjmlEmailService 和 SmtpClient 有不同的关注点。




SmtpClient：

public void SmtpEmailProcessor(string emailBody)
        {
            try
            {
                SmtpClient objsmtp = new SmtpClient("smtp.gmail.com", 587);
                objsmtp.UseDefaultCredentials = false;
                objsmtp.Credentials = new NetworkCredential("YourEmailId", "YourEmailPassword");
                objsmtp.DeliveryMethod = SmtpDeliveryMethod.Network;
                objsmtp.EnableSsl = true;
                MailMessage msg = new MailMessage("From Email", "To Email", "Subject: MJML Test", emailBody);
                msg.IsBodyHtml = true;
                objsmtp.Timeout = 50000;
                objsmtp.Send(msg);
            }
            catch (Exception ex) { }
        }

注意： 您可以查看有效的 SmtpClient 请求在此参考
