Generate Barcode in windows application


                  Here I have explained how to generate Barcode and Qrcode in windows application.


                  In my previous article I have explained How to lock a form or how to set a form as notmovable as well as fixed size .
Here I will explain how to generate barcode as well as qrcode using C#.I have provided all the procedures here to generate barcode and qrcode.

Follow the following process

First download QRCODE GENERATOR LIBRARY from and then add reference to OnBarcode.Barcode.Winforms.dll to your windows application.

Now I am going to provide all code, what I have written to generate Barcode as well as Qrcode.

using System;
using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Windows.Forms;

using OnBarcode.Barcode;

using System.Drawing.Imaging;



    public partial class Form1 : Form


        public Form1()




        private void Form1_Load(object sender, EventArgs e)




        private void GenerateQrcode(string _data, string _filename)


            QRCode qrcode = new QRCode();

            qrcode.Data = _data;

            qrcode.DataMode = QRCodeDataMode.Byte;

            qrcode.UOM = UnitOfMeasure.PIXEL;

            qrcode.X = 3;

            qrcode.LeftMargin = 0;

            qrcode.RightMargin = 0;

            qrcode.TopMargin = 0;

            qrcode.BottomMargin = 0;

            qrcode.Resolution = 72;

            qrcode.Rotate = Rotate.Rotate0;

            qrcode.ImageFormat = ImageFormat.Gif;



        private void GenerateBacode(string _data, string _filename)


            Linear barcode = new Linear();

            barcode.Type = BarcodeType.CODE11;

            barcode.Data = _data;



        private void Form1_Load_1(object sender, EventArgs e)




        private void button1_Click(object sender, EventArgs e)


            SaveFileDialog sfd = new SaveFileDialog();


            textBox2.Text = sfd.FileName.ToString()+".gif";


        private void button2_Click(object sender, EventArgs e)


            GenerateBacode(textBox1.Text, textBox2.Text);


        private void button3_Click(object sender, EventArgs e)


            GenerateQrcode(textBox1.Text, textBox2.Text);




Now Take look on the Windows form:-

Windows Form Design

After running this form it will display as

Run View

By click on Barcode Button it will create following Jpg image


By click on Qrcode it will create following  jpg  image


As I have explained above,you will generate the same Barcode and Qrcode image as per your requirements.
