C# QR Code Barcode Generator
C# QR Code Barcode Generating Component encode & print QR Code in .NET projects using C# with Visual Studio.
Overview - C#.NET QR Code Generator
QR Code C# .NET Barcode Generator for the creation of QR Code, a two-dimensional code, consisting of black modules arranged in a square pattern on a white background, in your C# .NET framework projects. It is also known as Denso Barcode, QRCode, Quick Response Code, and compatible with the ISO/IEC18004.

How to Create QR Code in .NET Applications Using C# Codes
After intalling KeepDynamic.BarCode.AspNet.dll or KeepDynamic.BarCode.Windows.dll to your .NET project, you can use follwing C# samlpe codes to generate high-quality QR Code image.
//Create a new QR Code barcode object in C#.NET,
QRCode barcode = new QRCode();

//Assign the data value to QR Code barcode symbology and QR Code encodes variable data length
barcode.CodeText = "Abc1234567";

 Choose DataMode for QR Code barcode that is going to generate
 Numeric data mode encodes numbers 0 through 9;
 AlphaNumeric encodes digits 0 to 9, all uppercase letters, and special characters(space, $ % * + - . / :);
 byte data mode encodes characters define in ISO/IEC 8859-1;
 Kanji data mode encodes Kanji characters;
barcode.DataMode = QRCodeDataMode.Auto;

//Select a QR Code version from QR Code version list
//Set the Error Correction Level(ECL) to QR Code
barcode.Version = QRCodeVersion.V6;
barcode.ECL = QRCodeECL.L;

//Enable the option of ProcessTilde when the tilde character "~" is necessary
barcode.ProcessTilde = true;

//Set the QR Code barcode graphic measurements as Pixel
barcode.GraphicsUnit = KeepDynamic.Barcode.Generator.GraphicsUnit.Pixel;

//Assign the values of bar module width to QR Code barcode
barcode.X = 4;

//Set the margins around the QR Code barcode symbology
barcode.LeftMargin = 16;
barcode.RightMargin = 16;
barcode.TopMargin = 16;
barcode.BottomMargin = 16;

 Set the resolution of QR Code barcode image that is drawn to,
 and change the QR Code barcode image orientation
barcode.Resolution = 72;
barcode.Rotate = Rotate.Rotate0;

 Set QR Code barcode drawing image format to PNG in C#
 Generate QR Code barcode image in C#
barcode.Format = System.Drawing.Imaging.ImageFormat.Png;

// other barcode outputting ways:
// output generated barcode to byte array
byte[] barcodeInBytes = barcode.drawBarcodeAsBytes();
// output generated barcode to Graphics object
Graphics graphics = ...;
// output generated barcode to Bitmap object
Bitmap barcodeInBitmap = barcode.drawBarcode();
// draw created barcode to HttpResponse object
HttpResponse response = ...;
// save generated barcode images to Stream object
Stream stream = ...;
Generate 1D & 2D Barcodes using C# QR Code Generator SDK
The C#.NET Barcode Generator can create most common linear (1d) and matrix (2d) bar code standards in C#.NET projects, including:
