In this tutorial, viewers learn how to implement a barcode scanner in a C# Windows Form application using Iron Barcode. The tutorial is conducted in Visual Studio 2022 and begins with setting up the necessary components, including an image box for displaying barcode images, buttons for browsing and scanning, and a text box for displaying the scanned barcode text. The process involves using the NuGet Package Manager to install Iron Barcode and ensuring both the software and library are updated to their latest versions for optimal performance.
The form.cs file plays a crucial role, where a string variable stores the path of the barcode image file. The tutorial demonstrates setting up an open file dialog in the browse button function to select an image file, filtering for common image types. Once a file is chosen, it's loaded into the picture box, and its path is stored.
In the scan button function, the tutorial highlights using Iron Barcode's read method to extract the barcode information from the image. The resulting text is displayed in the text box. The tutorial concludes with a demonstration of the project in action, showing the selection of a barcode image and the display of its text output in the application.
