How to read vcard from QR code in C# and ByteScout BarCode Reader SDK

This code in C# shows how to read vcard from QR code with this how to tutorial

On this page you will learn from code samples for programming in C#.Writing of the code to read vcard from QR code in C# can be done by developers of any level using ByteScout BarCode Reader SDK. 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. It can be used to read vcard from QR code using C#.

You will save a lot of time on writing and testing code as you may just take the C# code from ByteScout BarCode Reader SDK for read vcard from QR code below and use it in your application. This C# sample code is all you need for your app. Just copy and paste the code, add references (if needs to) and you are all set! Enjoy writing a code with ready-to-use sample codes in C#.
