Create QR Code in C#.

Introduction to QR Codes

QR codes have become an essential tool for modern data sharing and marketing. They provide a compact, scannable format that can encode a wide range of information. In this .NET tutorial, we will show you how to programmatically Create QR Code in C# using the Aspose.BarCode 2D Barcode Writer plugin. This guide is ideal for developers looking to integrate dynamic QR Code generation into desktop or ASP.NET applications.

Step 1: Install Aspose.BarCode for QR Code Generation

To begin generating QR codes, install the Aspose.BarCode for .NET library. This robust library simplifies the creation and recognition of various barcode types, including QR codes. You have two options:

  • Download the Aspose.BarCode DLL from the official download page.

  • Use the NuGet Package Manager by executing the following command in your Package Manager Console:

    PM> Install-Package Aspose.BarCode

For a complete solution, consider our $99 Aspose Plugin, which offers extensive functionalities for generating high-quality barcodes, including a C# QR Code Generator.

Step 2: Generate a Basic QR Code in C#

Creating a basic QR code is straightforward. Follow these steps:

  1. Instantiate a BarcodeGenerator object, specifying the QR encode type along with your desired text.
  2. Optionally configure customization options such as the error correction level.
  3. Generate the QR code and save it as an image file.

Below is a C# example demonstrating basic QR Code generation:

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

// Create a new BarcodeGenerator instance for QR Code
BarcodeGenerator generator = new BarcodeGenerator(EncodeTypes.QR, "Sample QR Code Content");
// Save the generated QR Code image
generator.Save("QRCode.png", BarCodeImageFormat.Png);

Step 3: Generate a QR Code with Custom Settings

To further customize your QR code, you can adjust settings such as error correction levels and dimensions. Here’s how to configure these options:

  1. Instantiate the BarcodeGenerator with your desired QR encode type.
  2. Set properties like error correction level, module size, and margins to match your application’s requirements.
  3. Generate the QR code and save it in the desired format.

Below is a snippet showcasing QR Code customization in C#:

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

// Create a BarcodeGenerator instance for QR Code
BarcodeGenerator generator = new BarcodeGenerator(EncodeTypes.QR, "Customized QR Code Content");
// Customize error correction level (e.g., High, Medium, Low)
generator.Parameters.Barcode.QR.QRCodeErrorLevel = QRCodeErrorLevel.H;
// Set additional customization options if needed
generator.Parameters.Barcode.XDimension.Pixels = 2;
// Save the customized QR Code image
generator.Save("CustomizedQRCode.png", BarCodeImageFormat.Png);
