C# Code 39 Generator Introduction
Top
Code 39, also known as Alpha39, Code 3 of 9, Code 3/9, Type 39, USS Code 39, or USD-3, is the first alpha-numeric linear barcode symbology used world-wide.
C# Code 39 Generator is one of the linear barcodes generation in OnBarcode's .NET Barcode Generation Controls, which generates & prints Code 39, Code 39 extension and other linear & 2D bar codes in C#.NET applications.
OnBarcode C# Barcode Generator makes it easy to generate, create Code 39 and other linear & 2d barcodes in Microsoft Word. Here are some detailed tutorials for C# Code 39 generation and data encoding, size & image setting.

Creating Code-39 barcode in C# class example:

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


Linear code39 = new Linear();

// Barcode data to encode
code39.Data = "ONBARCODE";
// Barcode symbology type
code39.Type = BarcodeType.CODE39;
// Apply checksum digit for Code-39
code39.AddCheckSum = true;

// The space between 2 characters in code 39; This a multiple of X; The default is 1.
code39.I = 1.0f;
// Wide/narrow ratio, 2.0 - 3.0 inclusive, default is 2.
code39.N = 2.0f;
// If true, display a * in the beginning and end of barcode text
code39.ShowStartStopInText = false;

/*
* Barcode Image Related Settings
*/
// Unit of meature for all size related setting in the library.
code39.UOM = UnitOfMeasure.PIXEL;
// Bar module width (X), default is 1 pixel;
code39.X = 1;
// Bar module height (Y), default is 60 pixel;
code39.Y = 60;
// Barcode image left, right, top, bottom margins. Defaults are 0.
code39.LeftMargin = 0;
code39.RightMargin = 0;
code39.TopMargin = 0;
code39.BottomMargin = 0;
// Image resolution in dpi, default is 72 dpi.
code39.Resolution = 72;
// Created barcode orientation.
//4 options are: facing left, facing right, facing bottom, and facing top

code39.Rotate = Rotate.Rotate0;

/*
* Linear barcodes human readable text styles
*/
// Display human readable text under the barcode
code39.ShowText = true;
// Display checksum digit at the end of barcode data.
code39.ShowCheckSumChar = true;
// Human readable text font size, font family and style
code39.TextFont = new Font("Arial", 9f, FontStyle.Regular);
// Space between barcode and text. Default is 6 pixel.
code39.TextMargin = 6;

// Generate Code-39 and encode barcode to gif format
code39.Format = System.Drawing.Imaging.ImageFormat.Gif;
code39.drawBarcode("C:\\code39.gif");

/*
You can also call other drawing methods to generate barcodes

public void drawBarcode(Graphics graphics);

public void drawBarcode(string filename);

public Bitmap drawBarcode();

public void drawBarcode(Stream stream);
