UPC-A, also known as Universal Product Code version A , UPC Code, UPC Symbol, GTIN-12, GS1-12, UCC-12, is the most common and well-known barcode symbology in the United States.

C# UPC-A Generator is one of the functions in OnBarcode's Barcode for .NET Generation Controls, which supports generating & printing UPC-A and 20+ other linear & 2D bar codes for C# applications.

OnBarcode C# Barcode Generator makes it easy to generate, create UPC-A and other linear & 2d barcodes in Microsoft Word. Here are some detailed tutorials for C# UPC-A generation and data encoding, size & image setting.

• Samples for UPC-A Data Encoding using C#
• Samples for UPC-A Size Setting using C#
• Samples for UPC-A Image Setting using C#

Creating UPC-A barcode in C# class example:

	using System.Collections.Generic;
	using System.Text;
	using OnBarcode.Barcode;
	using System.Drawing.Imaging;
	using System.Drawing;

            //upca.Type = BarcodeType.UPCA;
            upca.Type = BarcodeType.UPCA_2;
            // This property is not working in UPC-A. 
            // According to UPC-A specification, our library will always encode checksum for you.

             * Linear barcodes human readable text styles
