Important Update
Every ByteScout tool includes sample C# source codes that you can find here or in the folder with installed ByteScout product. ByteScout Cloud API Server was designed to assist barcode reader API in C#. ByteScout Cloud API Server is API server that is ready to use and can be installed and deployed in less than 30 minutes on your own Windows server or server in a cloud. It can save data and files on your local server-based file storage or in Amazon AWS S3 storage. Data is processed solely on the API server and is powered by ByteScout engine, no cloud services or Internet connection is required for data processing..
If you want to speed up the application’s code writing then C# code samples for C# developers help to implement using ByteScout Cloud API Server. This C# sample code can be used by copying and pasting into your project. Once done,just compile your project and click Run. Enjoy writing a code with ready-to-use sample C# codes to add barcode reader API functions using ByteScout Cloud API Server in C#.
ByteScout Cloud API Server – free trial version is available on our website. Also, there are other code samples to help you with your C# application included into trial version.
