C# Text to QR Code Generator API

To convert any text to a QR code, we use the Aspose.BarCode for .NET API. It supports generating, scanning, and reading barcodes and QR codes in .NET applications. The API lets developers save the generated barcode or QR code in formats such as PNG, JPEG, and TIFF. It covers more than 60 barcode symbols, including QR code, Code 128, Code 39, EAN, UPC, and many others.

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

PM> Install-Package Aspose.BarCode
