Get the text body content of a MIME part.

See more MIME Examples

Explains and demonstrates the GetBodyEncoded and GetBodyDecoded methods. This example uses the MIME test data located at http://www.chilkatsoft.com/testData/sampleMime1.txt

The sampleMime1.txt contains:

Content-Type: multipart/mixed;
 boundary="------------070404010201060604000708";

This is a multi-part message in MIME format.

Content-Transfer-Encoding: quoted-printable
Content-Type: text/plain; charset="utf-8";

//  This example assumes the Chilkat API to have been previously unlocked.
//  See Global Unlock Sample for sample code.

Chilkat.Mime mime = new Chilkat.Mime();

//  Load the sampleMime1.txt file into the MIME object.
//  (This file is available at http://www.chilkatsoft.com/testData/sampleMime1.txt )

//  The sampleMime1.txt is a MIME document with a top-level 
//  multipart/mixed containing 3 sub-parts, each of which has the 
//  same body text but with different content-transfer-encodings and 
//  using different character encodings (utf-8 and iso-8859-1).

//  Calling mime.GetBodyEncoded or mime.GetBodyDecoded on the 
//  top-level multipart/mixed MIME object will return an empty string.
//  It is because the "body" of a multipart MIME object is always empty.
//  A multipart MIME object contains sub-parts (each a MIME object),
//  and it is only the leaf-objects that can have non-empty bodies.

//  Get GetBodyDecoded method returns the body text decoded
//  from whatever the content-transfer-encoding may be, and
//  converted from whatever charset encoding might be used.
//  In this case, calling GetBodyDecoded on each of the three
//  sub-parts will return the same string.
//  To demonstrate:
Chilkat.Mime part1 = new Chilkat.Mime();
success = mime.PartAt(0,part1);

//  whatever content-transfer-encoding is used.  However, it will
//  convert from whatever internal character encoding
//  may be used to return a string appropriate for the calling
//  programming language (for example, in .NET or any language
//  using ActiveX, all strings are Unicode..)
