Add Binary Data to a ZIP Using AddBd

See more Zip Examples

This example demonstrates how to use the AddBd method to add binary data from a BinData object as a file entry within a ZIP archive.

The data is created entirely in memory, added to the ZIP as data/binary.dat, and then written to disk.

    //  Create a BinData object containing binary content.
    CkBinData bd = new CkBinData();

    //  Append some bytes as hexadecimal.
    //  The decoded bytes will become the contents of the ZIP entry.

    //  The file will be stored as "data/binary.dat" inside the ZIP archive.
