C# QR Code Generator is one of the functions in OnBarcode's Barcode for .NET Generation Controls, which supports generating & printing QR Code and 20+ other linear & 2D bar codes for C# applications.

OnBarcode C# Barcode Generator makes it easy to generate, create QR Code and other linear & 2d barcodes in Microsoft Word. Here are some detailed tutorials for C# QR Code generation and data encoding, size & image setting.

• Samples for QR Code Data Encoding using C#
• Samples for QR Code Size Setting using C#
• Samples for QR Code Image Setting using C#

Creating QR-Code barcode in C# class example:

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


            QRCode qrcode = new QRCode();

            // Barcode data to encode
            qrcode.Data = "ONBARCODE";
            // QR-Code data mode
            qrcode.DataMode = QRCodeDataMode.AlphaNumeric;
            // QR-Code format mode
            //qrcode.Version = QRCodeVersion.V10;

            /*
             * Barcode Image Related Settings
             */
            // Unit of meature for all size related setting in the library. 
            qrcode.UOM = UnitOfMeasure.PIXEL;
            // Bar module size (X), default is 3 pixel;
            qrcode.X = 3;
            // Barcode image left, right, top, bottom margins. Defaults are 0.
            qrcode.LeftMargin = 0;
            qrcode.RightMargin = 0;
            qrcode.TopMargin = 0;
            qrcode.BottomMargin = 0;
            // Image resolution in dpi, default is 72 dpi.
            qrcode.Resolution = 72;
            // Created barcode orientation. 4 options are: facing left, facing right, facing bottom, and facing top
            qrcode.Rotate = Rotate.Rotate0;

            // Generate QR-Code and encode barcode to gif format
            qrcode.ImageFormat = ImageFormat.Gif;
            qrcode.drawBarcode("C:\\barcodeimages\\qrcode.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);
             
             */
