An advanced MIME parser/creator/editor application.

Introduction

This article provides an advanced MIME editor. You can use it for parsing email messages, changing messages and for creating new email messages. It supports creation of complex messages with nested MIME entities. For more info, see help file: LumiSoft.Net.Mime namespace.

Message examples

Simple message:

//--- Beginning of message
From: sender@domain.com
To: recipient@domain.com
Subject: Message subject.
Content-Type: text/plain

Message body text. Bla blaa
blaa,blaa.
//--- End of message

In simple message, the MainEntity is the whole message.

Message with attachments:

//--- Beginning of message
From: sender@domain.com
To: recipient@domain.com
Subject: Message subject.
Content-Type: multipart/mixed; boundary="multipart_mixed"

--multipart_mixed    /* text entity */
Content-Type: text/plain

Message body text. Bla blaa
blaa,blaa.
--multipart_mixed    /* attachment entity */
Content-Type: application/octet-stream

attachment_data
--multipart_mixed--
//--- End of message

Here MainEntity is the multipart_mixed entity, and the text and attachment entities are child entities of MainEntity.

Using the code

Parsing example:

C#
Mime m = Mime.Parse("message.eml");
// Do your stuff with mime

Creating a new simple message:

C#
Mime m = new Mime();
MimeEntity mainEntity = m.MainEntity;
// Force to create From: header field
mainEntity.From = new AddressList();
mainEntity.From.Add(new MailboxAddress("dispaly name","user@domain.com"));
// Force to create To: header field
mainEntity.To = new AddressList();
mainEntity.To.Add(new MailboxAddress("dispaly name","user@domain.com"));
mainEntity.Subject = "subject";
mainEntity.ContentType = MediaType_enum.Text_plain;
mainEntity.ContentTransferEncoding = ContentTransferEncoding_enum.QuotedPrintable;
mainEntity.DataText = "Message body text.";

m.ToFile("message.eml");

Creating a message with text and attachments:

C#
Mime m = new Mime();
MimeEntity mainEntity = m.MainEntity;
// Force to create From: header field
mainEntity.From = new AddressList();
mainEntity.From.Add(new MailboxAddress("dispaly name","user@domain.com"));
// Force to create To: header field
mainEntity.To = new AddressList();
mainEntity.To.Add(new MailboxAddress("dispaly name","user@domain.com"));
mainEntity.Subject = "subject";
mainEntity.ContentType = MediaType_enum.Multipart_mixed;

MimeEntity textEntity = mainEntity.ChildEntities.Add();
textEntity.ContentType = MediaType_enum.Text_plain;
textEntity.ContentTransferEncoding = ContentTransferEncoding_enum.QuotedPrintable;
textEntity.DataText = "Message body text.";

MimeEntity attachmentEntity = mainEntity.ChildEntities.Add();
attachmentEntity.ContentType = MediaType_enum.Application_octet_stream;
attachmentEntity.ContentDisposition = ContentDisposition_enum.Attachment;
attachmentEntity.ContentTransferEncoding = ContentTransferEncoding_enum.Base64;
attachmentEntity.ContentDisposition_FileName = "yourfile.xxx";
attachmentEntity.DataFromFile("yourfile.xxx");
// or
attachmentEntity.Data = your_attachment_data;
