How to generate QR barcodes in C#
QR barcodes are machine-readable optical labels that contain certain information. Today we will be looking into how to generate QR codes with the use of the ZXing.Net library.
First you will need to download the ZXing.Net library from zxingnet.codeplex.com. Extract the contents of the file you have downloaded and reference the library that fits your needs in your project.
Using the example code below you will now be able to create your own QR codes.
1 2 3 4 5 6 7 8 9 10 | public Bitmap GenerateQR(int width, int height, string text) { var bw = new ZXing.BarcodeWriter(); var encOptions = new ZXing.Common.EncodingOptions() { Width = width, Height = height, Margin = 0 }; bw.Options = encOptions; bw.Format = ZXing.BarcodeFormat.QR_CODE; var result = new Bitmap(bw.Write(text)); return result; } |
Example: Calling the following method will return a Bitmap object which you can save using the Bitmap’s Bitmap.Save() method or simply display it within your application.
