How to add attachment in RFC822 format MAIL using Google API?

I am trying to add attachment in RFC822 format MAIL using Google API (c#).

Referring to this link

http://code.google.com/apis/apps/email_migration/developers_guide_dotnet.html

How should i start?

Can anyone give me sample mail value?

Is there any study material or documentation available on net.To understand Google Apps Email Migration API.

Since you're migrating messages I assume you have access to the original raw message, which should have everything in place already (all attachments correctly encoded for email transmission). If that's the case you just need to follow the example in Migrating Email Messages where rfcTextOfMessage is the full raw message you want to migrate.

There's a disconnect between what you're asking and what you want. Specifically, RFC 822 doesn't recognize attachments. As far as RFC 822 is concerned, an email is just a set of headers followed by the message body. There are several other RFC's you'll want to look at to see exactly how attachments are stored in email (989, 1421, 2822, and probably some others).

But the upshot is that you shouldn't have to worry about it. Simply take the entire raw message and put it in a CDATA section within the apps:rfc822Msg element. A sample:

<?xml version="1.0" encoding="utf-8"?>
<feed xmlns="http://www.w3.org/2005/Atom"
    xmlns:batch="http://schemas.google.com/gdata/batch"
    xmlns:gd="http://schemas.google.com/g/2005">
  <entry>
    <category term="http://schemas.google.com/apps/2006#mailItem" scheme="http://schemas.google.com/g/2005#kind" />
    <apps:rfc822Msg xmlns:apps="http://schemas.google.com/apps/2006">
