Project Description

A library which supports decoding and generating of barcodes (like QR Code, PDF 417, EAN, UPC, Aztec, Data Matrix, Codabar) within images.

The project is a port of the java based barcode reader and generator library ZXing.
https://github.com/zxing/zxing
It has been ported by hand with a lot of optimizations and improvements.

The following barcodes are supported by the decoder: UPC-A, UPC-E, EAN-8, EAN-13, Code 39, Code 93, Code 128, ITF, Codabar, MSI, RSS-14 (all variants), QR Code, Data Matrix, Aztec and PDF-417. The encoder supports the following formats: UPC-A, EAN-8, EAN-13, Code 39, Code 128, ITF, Codabar, Plessey, MSI, QR Code, PDF-417, Aztec, Data Matrix

Assemblies are available for the following platforms:

obsolete Assemblies are available for the following platforms up to release 0.16:

The library is available in the release section and as NuGet package, too.

Additional platform support without pre-built binaries

The library can be built for Xamarin.iOS (formerly MonoTouch). The project file and solution are available in the source code repository.

A special version for the .Net Micro Framework can be found in a separate branch in the source code repository.

The following demo clients are available:

Thanks

Many thanks to the team of the zxing project for their great work. ZXing.Net would not be possible without your work!

Usage examples

The source code repository includes small examples for Windows Forms, Windows Phone and other project types. Obsolete examples are available for the following platforms in separate branches: 0.16:

small example decoding a barcode inside a bitmap (.Net 2.0/3.5/4.x)

// create a barcode reader instance
IBarcodeReader reader = new BarcodeReader();
// load a bitmap
var barcodeBitmap = (Bitmap)Image.FromFile("C:\\sample-barcode-image.png");
// detect and decode the barcode inside the bitmap
var result = reader.Decode(barcodeBitmap);
// do something with the result
if (result != null)
{
   txtDecoderType.Text = result.BarcodeFormat.ToString();
   txtDecoderContent.Text = result.Text;
}

important notice for .Net Standard and .Net 5.0 and above target platforms

If you want to try the sample code above within a project which target .Net Standard or .Net 5.0 or higher then you have to add one of the additional nuget package for a specific image library: https://www.nuget.org/packages?q=ZXing.Bindings The main package of ZXing.Net for such platforms only contains the core classes which are not dependent on a specific assembly for image formats.
