Barcodes are used to visually represent the data in a machine-readable form. Most often, barcodes appear to be a means of a product’s identification. Various types of barcodes are used in different scenarios such as Code128, Code11, Code39, QR, Datamatrix, Aztec and etc. In this article, you will learn how to programmatically generate the barcodes using C#. Furthermore, you will see how to customize the appearance of a barcode.

The following code sample shows how to generate a customized Aztec barcode using C#.
Add Caption in Barcodes using C#
You might have seen barcodes with a caption above or below the barcode image. These captions can be used to display additional information related to the product or the barcode itself. Aspose.BarCode for .NET also allows you to add a caption below, above, or on both sides of the barcode. The following are the steps to add a caption.
- Create an object of BarcodeGenerator class.
- Set the barcode’s text and type in the constructor of BarcodeGenerator.
- Set caption using CaptionAbove or CaptionBelow properties.
- Save the barcode using BarcodeGenerator.Save(String) method.
The following code sample shows how to add caption in a barcode using C#.
