Fetch a Single Message's MIME into a StringBuilder
See more IMAP Examples
Demonstrates the Chilkat Imap.FetchSingleAsMimeSb method, which downloads one message's MIME into a StringBuilder. The first argument is the message id, the second (bUid) selects UID vs sequence number, and the third is the StringBuilder, which is cleared first. This example downloads a message by UID and prints the MIME length.
Background: Chilkat interprets the received MIME as UTF-8. Messages using Base64 or quoted-printable transfer encoding are safe because their encoded bytes are ASCII. Raw
8bit or binary content, or unencoded text in a charset such as ISO-8859-1 or Shift_JIS, can be misinterpreted — in those cases use FetchSingleBd to get the exact bytes.Chilkat Android™ Downloads
