Append Text to a Remote FTP File (StringBuilder)

See more FTP Examples

Demonstrates the Chilkat Ftp2.AppendFileSb method, which encodes the text in a StringBuilder and appends the bytes to a remote file. The arguments are the remote filename, the StringBuilder, and the charset.

Background: When you have accumulated several lines or records in a StringBuilder, this appends them to a remote file in one call, encoding as it writes. It pairs naturally with building up text in memory and flushing it to a remote log periodically.
