.NET QR Code Generator - Barcode QR-Code Introduction

QR Code is a matrix code (or two-dimensional bar code) created by Japanese corporation Denso-Wave in 1994. The "QR" is derived from "Quick Response", as the creator intended the code to allow its contents to be decoded at high speed.

.NET QR Code Generation - QR-Code Valid Data Scope

.NET QR Code Generator encodes:

• numeric data (digits 0 - 9);
  
  
• alphanumeric data (digits 0 - 9; upper case letters A -Z; nine other characters: space, $ % * + - . / : );
  
  
• byte data (default: ISO/IEC 8859-1);
  
  
• Kanji characters.

Generating barcode QR Code in C# Class example (C# QR Code Generator Complete Demo Source Code)

	        QRCode qrcode = new QRCode();
	        qrcode.Data = "0123456789";
	        qrcode.X = 3;
	        
	        // Generate QR-Code and encode barcode to gif format
	        qrcode.Format = ImageFormat.Gif;
	        qrcode.drawBarcode("c#-qrcode.gif");
	        
	        // Print QR-Code to C# Bitmap object
	        Bitmap qrcodeBitmap = qrcode.drawBarcode();

Generating barcode QR Code in VB.NET Class example (VB.NET QR Code Generator Complete Demo Source Code)

	        Dim qrcode As OnBarcode.Barcode.QRCode
	        qrcode = New OnBarcode.Barcode.QRCode()
	        qrcode.Data = "0123456789"
	        qrcode.X = 3
	        
	        // Generate QR-Code and encode barcode to png format
	        qrcode.Format = ImageFormat.Png
	        qrcode.drawBarcode("vbnet-qrcode.png")
	        
	        // Print QR-Code to vb.net Bitmap object
	        Dim qrcodeBitmap As Bitmap
	        qrcodeBitmap = qrcode.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/qrcode.aspx?DATA=0123456789
  
  
• To create barcode QR-Code image in html or aspx pages, you can insert a image tag (img) into your page.
  For example, <img src="http://YourDomain:Port/barcode/qrcode.aspx?DATA=0123456789" />
  
  

Creating QR-Code image in C# Class example

	        QRCode qrcode = new QRCode();
	        qrcode.Data = "0123456789";
	        qrcode.X = 3;
	        
	        // Create QR-Code and encode barcode to Jpeg format
	        qrcode.Format = ImageFormat.Jpeg;
	        qrcode.drawBarcode("C://csharp-qrcode.jpg");

Creating QR-Code image in VB.NET Class example

	        Dim qrcode As OnBarcode.Barcode.QRCode
	        qrcode = New OnBarcode.Barcode.QRCode()
	        qrcode.Data = "0123456789"
	        qrcode.X = 3
	        
	        // Create QR-Code and encode barcode to Jpeg format
	        qrcode.Format = ImageFormat.Jpeg
	        qrcode.drawBarcode("C://vbnet-qrcode.jpg")

To draw & print barcode QR-Code to C# objects:

	        public void drawBarcode(Graphics graphics);
	
	        public void drawBarcode(string filename);
	
	        public Bitmap drawBarcode();
	
	        public void drawBarcode(Stream fileStream);

To draw & print barcode QR-Code to VB.NET objects:

	        Public Sub drawBarcode(ByRef graphics As Graphics)
	
	        Public Sub drawBarcode(ByVal filename As String)
	
	        Public Function drawBarcode() As Bitmap
	
	        Public Sub drawBarcode(ByRef fileStream As Stream)
