How to Generate QR Code in C#

This tutorial explains how to generate QR codes in C#. Barcodes, especially 2D matrix barcodes like QR codes, have become common. Using Aspose.BarCode for .NET, you can create QR codes quickly with just a few lines of code.

Benefits of Generating QR Codes

  1. Ease of Data Sharing:
    • QR codes enable quick access to URLs, contact details, and other information.
  2. Versatile Applications:
    • Useful in marketing, payment systems, and inventory management.
  3. High Capacity:
    • Holds more data than traditional barcodes.

Prerequisites: Preparing the Environment

  1. Set up Visual Studio or any compatible .NET IDE.
  2. Install Aspose.BarCode from the NuGet Package Manager.

Step-by-Step Guide to Generate QR Code

Step 1: Install Aspose.BarCode

Add the Aspose.BarCode library to your project using NuGet.

Install-Package Aspose.BarCode

Step 2: Include the Necessary Namespaces

Add references to the required Aspose.BarCode namespaces.

using Aspose.BarCode;
using Aspose.BarCode.Generation;

Step 3: Create the BarcodeGenerator Instance

Instantiate the BarcodeGenerator class, specifying QR as the encoding type.

BarcodeGenerator QRCodeGenerator = new BarcodeGenerator(EncodeTypes.QR);

Step 4: Set the Barcode Text

Specify the text you want to encode in the QR code using the CodeText property.

QRCodeGenerator.CodeText = "Text To Encode";

Step 5: Save the Generated QR Code

Save the QR code image in the desired format (e.g., PNG).

QRCodeGenerator.Save("Generated_QR_Code.png", BarCodeImageFormat.Png);

Complete Code Example to Generate QR Code

Here’s a complete example demonstrating how to generate a QR

// Create an instance of the BarcodeGenerator class with QR as the encoding type
BarcodeGenerator QRCodeGenerator = new BarcodeGenerator(EncodeTypes.QR);

// Set text to be encoded as the generated QR code
QRCodeGenerator.CodeText = "Text To Encode";

// Save the generated QR code image in PNG format
QRCodeGenerator.Save("Generated_QR_Code.png", BarCodeImageFormat.Png);

Additional Information

  • You can save the QR code in various formats, including BMP, JPEG, and TIFF.
  • Adjust additional properties to customize the appearance of the QR code as needed.
