// Title: Batch Generation of GS1 Code 128 Barcodes from a List
// Description: Demonstrates creating GS1 Code 128 barcodes for each record and saving them as PNG files to a network share.
// Category-Description: This example belongs to the Aspose.BarCode generation category, illustrating how to use the BarcodeGenerator class with EncodeTypes.GS1Code128. Typical use cases include bulk barcode creation from database tables, exporting to shared locations, and integrating barcode assets into enterprise workflows. Developers often need to validate input, configure checksum display, and handle file system operations when automating barcode production.
// Prompt: Batch generate GS1 Code 128 barcodes from a database table, saving each image to a network share.
