C# QR Code Generator

QR codes are used to store a lot of data in a small space. They are easy to use and can be scanned by smartphones or other devices to open a website, watch a video, or access other encoded information. In this blog post, we will learn how to generate text-based QR codes programmatically in C#. We will provide a step-by-step guide and code snippets to help you develop your own text to QR code generator in C#.

This article covers the following topics:

  1. C# text to QR code generator API
  2. Convert text to QR code in C#
  3. Customize text to QR code generation
  4. Generate a QR code with text
  5. Text to QR code generator online

C# Text to QR Code Generator API

For converting any text to a QR code, we will use the Aspose.BarCode for .NET API. It allows generating, scanning, and reading barcodes and QR codes in .NET applications. The API allows developers to easily save the generated barcode or QR code in various image formats, such as PNG, JPEG, and TIFF. It supports over 60 barcode symbols, such as QR code, Code 128, Code 39, EAN, UPC, and many more.

Please download the DLL of the API or install it using the following NuGet command:

PM> Install-Package Aspose.BarCode

Convert Text to QR Code in C#

We can easily generate a QR code from any provided text by following the steps below:

  1. Create an instance of the BarcodeGenerator class.
  2. Set the EncodeTypes to QR.
  3. Specify the input text to encode.
  4. Optionally, specify QR code customization options.
  5. Finally, call the Save() method to save the generated QR code image at the given file path.

The following code sample shows how to convert a text to a QR code in C#.

Customize Text to QR Code Generation in C#

We can customize the appearance of QR codes generated from text by following the steps mentioned earlier. However, we need to set some additional properties to customize the background color, border color, image height, etc.

The following code sample shows how to customize text to QR code generation in C#.
