Important Update
These source code samples are assembled by their programming language and functions they use. ByteScout Cloud API Server was made to help with barcode reader API in C#. ByteScout Cloud API Server is the ready to deploy Web API Server that can be deployed in less than thirty minutes into your own in-house Windows server (no Internet connnection is required to process data!) or into private cloud server. Can store data on in-house local server based storage or in Amazon AWS S3 bucket. Processing data solely on the server using built-in ByteScout powered engine, no cloud services are used to process your data!.
If you want to quickly learn then these fast application programming interfaces of ByteScout Cloud API Server for C# plus the guideline and the C# code below will help you quickly learn barcode reader API. Follow the steps-by-step instructions from the scratch to work and copy and paste code for C# into your editor. C# application implementation mostly involves various stages of the software development so even if the functionality works please check it with your data and the production environment.
