How to Generate a QR Code Using C#

In this tutorial, we delve into generating and reading QR codes using the IronQR library in C#. To begin, please ensure the IronQR library is installed via a package manager such as NuGet. This tutorial assumes prior installation to save time. Navigate to the Program.cs file where pre-written code awaits. Start by including essential namespaces: IronBarCode and IronSoftware.Drawing. Remember to set your license key by replacing the placeholder with your actual key.

Next, create a QR code object and embed a simple message like 'Hello from IronQR.' Once the QR code is generated, save it as a bitmap and a file named qr.PNG. To read the QR code, load the saved image and employ the BarcodeReader class to extract its information. Run the project to see the QR code generation in action.

Upon running, the QR code is successfully created and saved as qr.PNG. The program then reads the QR code, displaying its value on the console, confirming successful reading and extraction of the message. Finally, you can view the generated qr.PNG file. This wraps up the tutorial on using IronQR for creating and reading QR codes in C#. For more tutorials and a trial subscription link, visit Iron Software’s website.
