深入Lumisoft.NET实现邮件发送功能的方法详解(6)

using (SMTP_Client client = new SMTP_Client())
                    {
                        int port = domainInfo.Ssl ? WellKnownPorts.SMTP_SSL : WellKnownPorts.SMTP;
                        if (domainInfo.Port > 0)
                        {
                            port = domainInfo.Port;
                        }

client.Connect(domainInfo.SmtpServer, port, domainInfo.Ssl);
                        client.Authenticate(domainInfo.Username, domainInfo.Password);
                        //string text = client.GreetingText;
                        client.MailFrom(mailFrom, -1);
                        client.RcptTo(mailTo);

MemoryStream stream = Create_Html_Attachment_Image(mailTo, mailFrom, mailFromDisplay);
                        client.SendMessage(stream);
                        client.Disconnect();
                    }

其中构造邮件内容的代码和刚才的部分类似，详细代码如下所示。

复制代码 代码如下:

private MemoryStream Create_Html_Attachment_Image(string mailTo, string mailFrom, string mailFromDisplay)
        {
            Mime m = new Mime();
            MimeEntity mainEntity = m.MainEntity;

mainEntity.From = new AddressList();
            mainEntity.From.Add(new MailboxAddress(mailFromDisplay, mailFrom));

mainEntity.To = new AddressList();
            mainEntity.To.Add(new MailboxAddress(mailTo, mailTo));
            mainEntity.Subject = mailInfo.Title;
            mainEntity.ContentType = MediaType_enum.Multipart_mixed;

MimeEntity textEntity = mainEntity.ChildEntities.Add();
            textEntity.ContentType = MediaType_enum.Text_html;
            textEntity.ContentTransferEncoding = ContentTransferEncoding_enum.QuotedPrintable;
            textEntity.DataText = mailInfo.Content;
.........................        

MemoryStream msg = new MemoryStream();
            m.ToStream(msg);
            msg.Position = 0;

return msg;
        }

利用Lumisoft.NET这个组件，可以实现很多相关的邮件操作，这里介于兴趣及篇幅原因，主要介绍邮件发送的功能模块，其中贴出的代码，一个是为了和感兴趣的朋友相互交流，一个也是为了自己今后做一个借鉴，并不鼓励大家用此软件或者代码来大批量发送垃圾邮件。
