Add Text Files to a ZIP Using AddString

See more Zip Examples

This example demonstrates how to use the AddString method to add multiple text files directly from string variables into a ZIP archive.

Each string is converted to bytes using the specified character encoding and stored as a separate file entry within the ZIP archive.

This method is useful for dynamically generating small text files such as configuration files, reports, JSON documents, XML, or log files entirely in memory.
