深入Lumisoft.NET实现邮件发送功能的方法详解(4)

if (timer != null)
                {
                    timer.Stop();
                    timer.Dispose();
                }
            }
            catch (Exception ex)
            {
                LogTextHelper.WriteLine(ex.ToString());
            }

UpdateFinishStatus();
        }

其中具体的邮件发送功能封装在SendJobInfo中，通过判断不同的类型，进行不同的发送操作。

其中最为关键的发送代码，就是如何利用LumiSoft.NET组件来构造相应的邮件对象，下面先先介绍下邮件直投的发送方式，由于该组件封装比较好，直投发送方式很简单：

复制代码 代码如下:

Mail_Message message = Create_PlainText_Html_Attachment_Image(mailTo, mailFrom, mailFromDisplay);
SMTP_Client.QuickSend(message);

其中Create_PlainText_Html_Attachment_Image的封装函数详细内容如下所示：

复制代码 代码如下:

代码

private Mail_Message Create_PlainText_Html_Attachment_Image(string mailTo, string mailFrom, string mailFromDisplay)
        {
            Mail_Message msg = new Mail_Message();
            msg.MimeVersion = "1.0";
            msg.MessageID = MIME_Utils.CreateMessageID();
            msg.Date = DateTime.Now;
            msg.From = new Mail_t_MailboxList();
            msg.From.Add(new Mail_t_Mailbox(mailFromDisplay, mailFrom));
            msg.To = new Mail_t_AddressList();
            msg.To.Add(new Mail_t_Mailbox(mailTo, mailTo));
            msg.Subject = mailInfo.Title;

//设置回执通知
            string notifyEmail = SystemConfig.Default.DispositionNotificationTo;
            if (!string.IsNullOrEmpty(notifyEmail) && ValidateUtil.IsEmail(notifyEmail))
            {
                msg.DispositionNotificationTo = new Mail_t_Mailbox(notifyEmail, notifyEmail);
            }

#region MyRegion
            //--- multipart/mixed -----------------------------------
            MIME_h_ContentType contentType_multipartMixed = new MIME_h_ContentType(MIME_MediaTypes.Multipart.mixed);
            contentType_multipartMixed.Param_Boundary = Guid.NewGuid().ToString().Replace('-', '.');
            MIME_b_MultipartMixed multipartMixed = new MIME_b_MultipartMixed(contentType_multipartMixed);
            msg.Body = multipartMixed;

//--- multipart/alternative -----------------------------
            MIME_Entity entity_multipartAlternative = new MIME_Entity();
            MIME_h_ContentType contentType_multipartAlternative = new MIME_h_ContentType(MIME_MediaTypes.Multipart.alternative);
            contentType_multipartAlternative.Param_Boundary = Guid.NewGuid().ToString().Replace('-', '.');
            MIME_b_MultipartAlternative multipartAlternative = new MIME_b_MultipartAlternative(contentType_multipartAlternative);
            entity_multipartAlternative.Body = multipartAlternative;
            multipartMixed.BodyParts.Add(entity_multipartAlternative);
