How do I generate a QR Code in C#?

Add the Neodynamic.SDK.BarcodeCore NuGet package, create a BarcodeProfessional object, set Symbology = Symbology.QRCode and Code to the value to encode, and call Save() to write a PNG file or GetBarcodeImage() to get the image bytes.

Which .NET versions are supported?

Barcode Professional is a .NET Standard 2.0 library, so it works on .NET Framework 4.6.1+, .NET Core 2.0+, modern .NET (.NET 5 and later), Mono 5.4+, Xamarin.iOS 10.14+, Xamarin.Android 8.0+, Xamarin.Mac 3.8+ and UWP 10.0.16299+.

Does it run on Linux and macOS?

Yes. It renders barcodes with SkiaSharp, so it runs on Windows, Linux and macOS, including ASP.NET Core apps in Linux containers.

Which barcode types are supported?

More than 100 linear (1D), postal, stacked, composite and 2D symbologies, including Code 39, Code 128, GS1-128, GS1 DataBar, EAN-13, UPC-A, ITF-14, Data Matrix, GS1 DataMatrix, QR Code, GS1 QR Code, Micro QR, rMQR, PDF417, Aztec Code, MaxiCode, Han Xin Code, DotCode, Swiss QR Code, JAB-Code, USPS Intelligent Mail, Royal Mail Mailmark and Australia Post.

Which image formats can it generate?

Raster formats PNG, JPEG, PCX, TIFF and PCL, PDF, and the vector formats SVG and EPS. PNG and JPEG support custom DPI for high-resolution printing.

Does it use barcode fonts?

No. It is a graphic-based engine, so there are no fonts to install on servers or client machines and barcodes render the same in every environment.

Are the barcodes GS1 and ISO/IEC compliant?

Yes. The encoders follow the GS1, ISO/IEC and AIM specifications, with auto-checksum, data validation and Bar Width Adjustment, so the barcodes pass verification required in retail, healthcare, postal and logistics.

Can I use it from Java, Python, PHP or Node.js?

The SDK is for .NET. For any other language use BarcodePro Web API for Docker, which exposes the same barcode engine as a REST API.

Quick Start: Generate a QR Code in C#

Install the NuGet package Neodynamic.SDK.BarcodeCore: dotnet add package Neodynamic.SDK.BarcodeCore (it uses SkiaSharp and System.Text.Encoding.CodePages).
Create a BarcodeProfessional object, set the Symbology and the Code to encode.
Call Save() or GetBarcodeImage().

Save a barcode image or get its bytes

using Neodynamic.SDK.BarcodeCore;
using SkiaSharp;

using (var bc = new BarcodeProfessional())
{
    bc.Symbology = Symbology.QRCode;     // or DataMatrix, Code128, GS1128...
    bc.Code = "ABC123";

    // save to disk
    bc.Save("barcode.png", SKEncodedImageFormat.Png);

    // or get the image bytes
    byte[] png = bc.GetBarcodeImage(SKEncodedImageFormat.Png);
}

Serve barcodes from an ASP.NET Core controller

[ApiController]
[Route("barcode")]
public class BarcodeController : ControllerBase
{
    [HttpGet("{value}")]
    public IActionResult Get(string value)
    {
        using var bc = new BarcodeProfessional
        {
            Symbology = Symbology.QRCode,
            Code = value
        };
        return File(bc.GetBarcodeImage(SKEncodedImageFormat.Png, 96), "image/png");
    }
}

// In any view or HTML page:
// <img src="/barcode/ABC12345" alt="QR Code" />

For Razor views you can also embed barcodes inline with BarcodeHtmlHelper.EmbedBarcodeImage(). See the ASP.NET Core guide.
