深入Lumisoft.NET组件与.NET API实现邮件发送功能的对(7)

//设置统一回复地址
            if (!string.IsNullOrEmpty(replyEmail) && ValidateUtil.IsEmail(replyEmail))
            {
                mainEntity.ReplyTo = new AddressList();
                mainEntity.ReplyTo.Add(new MailboxAddress(replyEmail, replyEmail));
            }

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

//附件
            foreach (string attach in attachments)
            {
                MimeEntity attachmentEntity = mainEntity.ChildEntities.Add();
                attachmentEntity.ContentType = MediaType_enum.Application_octet_stream;
                attachmentEntity.ContentDisposition = ContentDisposition_enum.Attachment;
                attachmentEntity.ContentTransferEncoding = ContentTransferEncoding_enum.Base64;
                FileInfo file = new FileInfo(attach);
                attachmentEntity.ContentDisposition_FileName = file.Name;
                attachmentEntity.DataFromFile(attach);
            }

//嵌入图片
            foreach (string key in embedImages.Keys)
            {
                MimeEntity attachmentEntity = mainEntity.ChildEntities.Add();
                attachmentEntity.ContentType = MediaType_enum.Application_octet_stream;
                attachmentEntity.ContentDisposition = ContentDisposition_enum.Inline;
                attachmentEntity.ContentTransferEncoding = ContentTransferEncoding_enum.Base64;
                string imageFile = embedImages[key];
                FileInfo file = new FileInfo(imageFile);
                attachmentEntity.ContentDisposition_FileName = file.Name;

//string displayName = Path.GetFileNameWithoutExtension(fileName);
                attachmentEntity.ContentID = key;//BytesTools.BytesToHex(Encoding.Default.GetBytes(fileName));

attachmentEntity.DataFromFile(imageFile);
            }

return m;
        }

综合以上两者的发送功能，都可以实现邮件的发送操作，如下界面是发送邮件界面。

3、LumiSoft.NET存储eml邮件文件以及发送eml文件操作

除了上面的发送普通邮件，Lumisoft还支持吧邮件序列号存储到文件(.eml邮件文件)里面，然后也可以通过把文件读取到流里面，进行发送，对于某种场合，可以把邮件存储到eml文件是一个很好的操作。

存储EML文件的相关操作如下所示。
