How to Read Barcodes From Images in C#

In this tutorial, we delve into reading barcodes from images using Iron Barcode in C#. After installing Iron Barcode via the NuGet package manager, we proceed to the program's CS file to explore the code. The process begins with declaring the Iron Barcode namespace, followed by utilizing the BarcodeReader.Read method to input the image file path. A foreach loop is implemented to iterate over detected barcodes, printing each barcode's value to the console. The demonstration involves a single barcode, but the code supports multiple barcodes. Upon running the program, the console displays the barcode's string representation, which may include numbers, letters, or a combination of both. This confirms the successful reading of the barcode.

            // Read barcodes from the image file
            var barcodes = BarcodeReader.Read(imagePath);

            // Iterate over each detected barcode
            foreach (var barcode in barcodes)
