.NET Barcode Codabar Generator for .NET, C#, ASP.NET, VB.NET
.NET Barcode offers the most affordable .NET barcode generator for barcode .NET professionals.
.NET Codabar Introduction
Codabar is also known as Codeabar, Ames Code, NW-7, Monarch, Code 2 of 7, Rationalized Codabar, ANSI/AIM BC3-1995 or USD-4.
Codabar is a linear barcode symbology developed in 1972 by Pitney Bowes Corp. It was designed to be accurately read even when printed on dot-matrix printers for multi-part forms such as FedEx airbills and blood bank forms, where variants are still in use as of 2007.
This symbology is used by U.S. blood banks, photo labs, and on FedEx airbills. Because Codabar is self-checking, it does not define a check digit. This symbology starts and finishes with one of four possible characters A, B, C, or D.

.NET Barcode Generator - How to generate barcodes in C# Class?
The following C# .NET code illustrates how to generate a barcode in C# class:
using KeepDynamic.Barcode.Generator;
// Create linear barcode object in C#
BarCode barcode = new BarCode();
// Set barcode symbology type to Code-39 in C#
barcode.SymbologyType = SymbologyType.Code39;
// Set Code39 barcode value in C#
barcode.CodeText = "CODE39";
// Set Code39 drawing image format to PNG in C#
barcode.Format = ImageFormat.Png;
// Generate Code-39 barcode & encode to the png image in C#
barcode.drawBarcode("C://barcode-code39-csharp.png");
// Generate Code-39 barcode & print to System.Drawing.Graphics object in C#
barcode.drawBarcode("Graphics object");
// Create Code-39 barcode & draw to System.IO.Stream object in C#
barcode.drawBarcode("Stream object");
// Create linear barcode object in C#
BarCode barcode = new BarCode();
// Set barcode symbology type to Code-39 in C#
barcode.SymbologyType = SymbologyType.Code39;
// Set Code39 barcode value in C#
barcode.CodeText = "CODE39";
// Set Code39 drawing image format to PNG in C#
barcode.Format = ImageFormat.Png;
// Generate Code-39 barcode & encode to the png image in C#
barcode.drawBarcode("C://barcode-code39-csharp.png");
// Generate Code-39 barcode & print to System.Drawing.Graphics object in C#
barcode.drawBarcode("Graphics object");
// Create Code-39 barcode & draw to System.IO.Stream object in C#
barcode.drawBarcode("Stream object");
.NET Barcode Generator - How to create barcodes in VB.NET Class?
The following VB.NET code illustrates how to generate a barcode in VB.NET class:
// Create linear barcode object in VB.NET
Dim barcode As KeepDynamic.Barcode.Generator.BarCode
barcode = New KeepDynamic.Barcode.Generator.BarCode()
// Set barcode symbology type to Code-39 in VB.NET
barcode.SymbologyType = SymbologyType.Code39;
// Set Code39 barcode value in VB.NET
barcode.CodeText = "CODE39"
// Set Code39 drawing image format to PNG in VB.NET
barcode.Format = ImageFormat.Png
// Generate Code-39 barcode & encode to the png image in VB.NET
barcode.drawBarcode("C://barcode-code39-vbnet.png")
// Generate Code-39 barcode & print to System.Drawing.Graphics object in VB.NET
barcode.drawBarcode("Graphics object")
// Create Code-39 barcode & draw to System.IO.Stream object in VB.NET
barcode.drawBarcode("Stream object")
Dim barcode As KeepDynamic.Barcode.Generator.BarCode
barcode = New KeepDynamic.Barcode.Generator.BarCode()
// Set barcode symbology type to Code-39 in VB.NET
barcode.SymbologyType = SymbologyType.Code39;
// Set Code39 barcode value in VB.NET
barcode.CodeText = "CODE39"
// Set Code39 drawing image format to PNG in VB.NET
barcode.Format = ImageFormat.Png
// Generate Code-39 barcode & encode to the png image in VB.NET
barcode.drawBarcode("C://barcode-code39-vbnet.png")
// Generate Code-39 barcode & print to System.Drawing.Graphics object in VB.NET
barcode.drawBarcode("Graphics object")
// Create Code-39 barcode & draw to System.IO.Stream object in VB.NET
barcode.drawBarcode("Stream object")
How to create barcodes in Windows Forms Applications
To create linear & 2D barcodes in Windows Forms applications, do the following procedures:
