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.
It has been ported by hand with a lot of optimizations and improvements.
There is a mirror of the repository at github:
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:
- .Net 2.0, 3.5, 4.0, 4.5 and 4.6
- Silverlight 4 and 5
- Windows Phone 7.0, 7.1 and 8.0
- Windows CE
- Windows RT Class Library and Runtime Components (winmd)
- Portable Class Library
- Unity3D (.Net 2.0 built without System.Drawing reference)
- Xamarin.Android (formerly Mono for Android)
- .Net Standard 1.6
The library is available in the download section and as
Additional platform support without pre-built binaries
The library can be built for Xamarin.iOS (formerly MonoTouch). The project file and solution is 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

Many thanks to the team of the zxing project
for their great work. ZXing.Net would not be possible without your work!
The source code repository includes small examples for Windows Forms, Silverlight and Windows Phone.
small example decoding a barcode inside a bitmap (.Net 2.0/3.5/4.0)
// create a barcode reader instance
IBarcodeReader reader = new BarcodeReader();
// load a bitmap
var barcodeBitmap = (Bitmap)Bitmap.LoadFrom("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;
All help is welcome!
