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.

--------------070404010201060604000708
Content-Transfer-Encoding: quoted-printable
Content-Type: text/plain; charset="utf-8";

    // 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.
