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:

Barcode Generation in ASP.NET - Creating barcodes in ASP.NET Web applications
Barcode Generation in Windows Forms - Printing barcodes in C#, VB.NET Windows Forms applications
Barcode Generation in Reporting Service - Drawing barcodes in Microsoft Reporting Service 2005 & 2008

 

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

GS1-128 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 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 = ImageFormat.Gif;
	        ean128.drawBarcode("c#-ean128.gif");

 

Generating barcode GS1-128/UCC/EAN-128 in C# Class example (C# Source Code to Create GS1-128/UCC/EAN-128 barcodes)

	        Linear ean128 = new Linear();
	        ean128.Type = BarcodeType.EAN128;
	        ean128.Data = "(00)350123451234567894";
	        ean128.X = 1;
	        ean128.Y = 60;
	        
	        // Generate GS1-128/UCC/EAN-128 and encode barcode to gif format
	        ean128.Format = ImageFormat.Gif;
	        ean128.drawBarcode("c#-ean128.gif");
	        
	        // Print GS1-128/UCC/EAN-128 to C# Bitmap object
	        Bitmap ean128Bitmap = ean128.drawBarcode();

Generating barcode GS1-128/UCC/EAN-128 in VB.NET Class example

	        Dim ean128 As OnBarcode.Barcode.Linear
	        ean128 = New OnBarcode.Barcode.Linear()
	        ean128.Type = OnBarcode.Barcode.BarcodeType.EAN128
	        ean128.Data = "(00)350123451234567894"
	        ean128.X = 1
	        ean128.Y = 60
	        
	        // Generate GS1-128/UCC/EAN-128 and encode barcode to png format
	        ean128.Format = ImageFormat.Png
	        ean128.drawBarcode("vbnet-ean128.png")
	        
	        // Print GS1-128/UCC/EAN-128 to vb.net Bitmap object
	        Dim ean128Bitmap As Bitmap
	        ean128Bitmap = ean128.drawBarcode();

 

• Under demo package, copy barcode folder and its contents to your IIS, and create a new virtual directory.
  
  
• Restart IIS, navigate to http://YourDomain:Port/barcode/linear.aspx?DATA=(00)350123451234567894&TYPE=11
  
  
• To create barcode GS1-128/UCC/EAN-128 image in html or aspx pages, you can insert a image tag (img) into your page.
  For example, <img src="http://YourDomain:Port/barcode/linear.aspx?DATA=(00)350123451234567894&TYPE=11" />
