Question

这个问题应该非常简单，但基本上我正在寻找一种使用asp.net中的电子邮件消息类发送html电子邮件的方法。在我的调试站点上，邮件客户端是一个pop服务器，因此我只使用SmtpClient并使用MailMessage类添加AlternateView发送。实时站点使用Exchange服务器，因此我必须添加Exchange凭据并使用EMailMessage类发送，但电子邮件消息未定义AlternateView。我在Google上找到这个答案的时候非常困难。这是我获取HTML页面和发送电子邮件的两种方法：

 private void emailUserPass(UserInfo info)
        {
            try
            {
                string body = string.Empty;
                using (StreamReader welcomeEmailReader = new StreamReader(Server.MapPath("~/path")))
                {
                    body = welcomeEmailReader.ReadToEnd();
                }
                body = body.Replace("{ID}",info.ID.ToString());
                body = body.Replace("{Password}", info.Password);
                List<string> to = new List<string>(); to.Add(info.Email);

                SendEMail("New Login", body, to, new List<string>(), new List<string>());
            }
            catch(Exception ex)
            {
                ShowError("Could not send the e-mail - error: " + ex.Message);
            }
        }



        public static void SendEMail(string subject, string body, List<string> to, List<string> cc, List<string> bcc)
        {
            #if DEBUG
                SmtpClient client = new SmtpClient("smtpout.secureserver.net", 25);
                client.Credentials = new System.Net.NetworkCredential("login", "password");
                MailMessage msg = new MailMessage("email", "email");
                msg.Subject = subject;
                body = body.Replace("{To}","To " + string.Join(",", to));
                body = body.Replace("{CC}","CC " + string.Join(",", cc));
                body = body.Replace("{BCC}", "BCC " + string.Join(",", bcc));
                AlternateView plain = AlternateView.CreateAlternateViewFromString(body, null, "text/plain");
                AlternateView normal = AlternateView.CreateAlternateViewFromString(body, null, "text/html");
                msg.AlternateViews.Add(plain);
                msg.AlternateViews.Add(normal);
                client.Send(msg);
#else
            ServicePointManager.Expect100Continue = true;
                ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3;
                ServicePointManager.ServerCertificateValidationCallback = delegate(object s, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors) { return true; };
                ExchangeService exService = new ExchangeService(ExchangeVersion.Exchange2007_SP1);

                exService.UseDefaultCredentials = false;
                exService.Credentials = new NetworkCredential("No_reply_programs", "blah", "blah");
                exService.Url = new Uri("ExchangeURL");

                body = body.Replace("{To}",string.Empty);
                body = body.Replace("{CC}",string.Empty);
                body = body.Replace("{BCC}",string.Empty);

                EmailMessage msg = new EmailMessage(exService);
                AlternateView plain = AlternateView.CreateAlternateViewFromString(body, null, "text/plain");
                AlternateView normal = AlternateView.CreateAlternateViewFromString(body, null, "text/html");
                msg.AlternateViews.Add(plain);
                msg.AlternateViews.Add(normal);
                msg.Subject = subject;
                foreach (string address in to)
                    msg.ToRecipients.Add(address);
                foreach (string address in cc)
                    msg.CcRecipients.Add(address);
                foreach (string address in bcc)
                    msg.BccRecipients.Add(address);
                msg.BccRecipients.Add("BccRecipient");
                msg.Send();
#endif
        }

Answer 1

这将是：

EmailMessage msg = new EmailMessage(exService);
//assing body 1st:
msg.Body= "string in Html format with tags and stuff";
msg.Body.BodyType = BodyType.HTML;
...

通过asp.net中的EmailMessage发送HTML消息
