Generate and Draw QR Code 1D Barcodes in C#.NET Classes

1. Download the QR Code barcode generation SDK folder and unzip it. Copy the barcode generation dll to your C#.NET project folder.
2. Open your project in Visual Studio; add QR Code barcode generation dll to project reference.
3. Right click the form, choose (view code) in the list. Barcodes could be created easily by adding C# code.

// Create linear barcode object
qrcode = new BarCode(); 
//Barcode symbology setting
qrcode = Symbology.QRCode    
//Barcode encoded data setting 
qrcode = "0123456789"

// If true, apply checksum digit characters in the input data. Default is false.
qrcode.AddCheckSum = true;
Format setting for QR Code with C#.NET
// If true, display the human readable text under the barcode
qrcode.ShowText = true; 
// If true, display the checksum digit 
qrcode. ShowCheckSum Char = true; 
// Text font setting 
qrcode.TextFont = new Font("Arial", 9f, FontStyle.Regular); 
// Set the space between barcode and text. Default is 6 pixel.
qrcode.TextMargin = 6; 
Color setting for QR Code with C#.NET
//Background color setting, Default is white.
qrcode. BackgroundColor = white; 
//Foreground color setting, Default is black.
qrcode. ForegroundColor = black; 
QR Code Special Setting
// If true, apply the tilde character "~" to specify special characters in the input data.
qrcode. EnableTilde = true;
