.NET Barcode GS1 128 / EAN 128 Generator Introduction
Top
Generating Barcode GS1-128/UCC/EAN-128 in .NET is one of the functions in OnBarcode's .NET Barcode Generators, which supports creating & printing GS1-128/UCC/EAN-128 and 30+ other linear & 2D bar codes for C#, VB.NET & ASP.NET applications.
OnBarcode develops several .NET Barcode Generation components for different .NET development environments:

.NET GS1-128/UCC/EAN-128 Generator - Barcode GS1-128/UCC/EAN-128 Introduction

GS1-128, former known as EAN-128, UCC-128, USS-128, is an application standard of the GS1 implementation using the Code 128 barcode specification. The former correct name was UCC/EAN-128. Other no longer used names have included UCC-128 and EAN-128. GS1-128 uses a series of Application Identifiers to include additional data such as best before dates, batch numbers, quantities, weights and many other attributes needed by the user.

.NET GS1-128/UCC/EAN-128 Generation - GS1-128/UCC/EAN-128 Valid Data Scope

.NET EAN-128 / GS1-128 Generator DLL encodes:
  • all 128 characters of ASCII
  • values 128-255 in accordance with ISO 8859-1. There are referred to as extended ASCII

GS1 Function Code 1 (FNC1) and the Application Identifier (AI)

OnBarcode .NET Barcode Generator allows easily to add application identifiers in GS1 128 / EAN 128, by add parentheses to AIs.
For example, to encode AI (00), with data 350123451234567894, with second AI (21), with data 01234567,you need pass string "(00)350123451234567894(21)01234567" to barcode Data property.
   Linear ean128 = new Linear();
ean128.Type = BarcodeType.EAN128;
ean128.Data = "(00)350123451234567894(21)01234567";

ean128.Format = System.Drawing.Imaging.ImageFormat.Gif;
ean128.drawBarcode("c://csharp-ean128.gif");
