Add Base64-Encoded Data to a ZIP Using AddEncoded

See more Zip Examples

This example demonstrates how to use the AddEncoded method to add encoded binary data as a file entry within a ZIP archive.

The example adds Base64-encoded data as a file named hello.txt within the ZIP archive. The Base64 text is automatically decoded to its original binary bytes before being stored in the ZIP.

This method is useful when binary data already exists in encoded textual form, such as Base64 or hex.
