Upload Text to an FTP Server (StringBuilder)

See more FTP Examples

Demonstrates the Chilkat Ftp2.PutFileSb method, which encodes the text in a StringBuilder and uploads it to a remote path. The arguments are the StringBuilder, the charset, whether to include a byte-order mark, and the remote file path.

Background: The text-oriented upload: assemble a document — CSV, config, JSON — in a StringBuilder and the method handles encoding as it writes. The charset governs the bytes actually stored, and the byte-order-mark flag is useful when a consuming Windows application expects a BOM.
