How to acquire barcode from scanner and decode in C# with ByteScout BarCode Reader SDK

Tutorial on how to acquire barcode from scanner and decode in C#

The coding tutorials are designed to help you test the features without need to write your own code. ByteScout BarCode Reader SDK can acquire barcode from scanner and decode. It can be used from C#. ByteScout BarCode Reader SDK is the SDK for reading of barcodes from PDF, images and live camera or video. Almost every common type like Code 39, Code 128, GS1, UPC, QR Code, Datamatrix, PDF417 and many others are supported. Supports noisy and defective images and docs. Includes optional documents splitter and merger for pdf and tiff based on found barcodess. Batch mode is supported for superior performance using multiple threads. Decoded values are easily exported to JSON, CSV, XML and to custom format.

This rich sample source code in C# for ByteScout BarCode Reader SDK includes the number of functions and options you should do calling the API to acquire barcode from scanner and decode. Just copy and paste the code into your C# application’s code and follow the instruction. Implementing C# application typically includes multiple stages of the software development so even if the functionality works please test it with your data and the production environment.
