In this video tutorial, we delve into the process of reading barcodes using the Iron Barcode Library in conjunction with System.Drawing objects. The session begins by ensuring the Iron Barcode Library is installed via the NuGet package manager. Moving on to the program.cs file, we import essential namespaces: Iron Barcode for barcode functionality and Iron Software.Drawing for image handling. We then initialize a list of AnyBitmap to hold the barcodes, loading a barcode image as a System.Drawing.Bitmap and casting it into an AnyBitmap object. This is followed by adding the image to the barcode list. Similarly, a QR code image is loaded and added to the list. Iterating through the list, each barcode is read using the ReadBarcode method, which returns detected barcodes that are printed on the console. The tutorial showcases the ease of using Iron Barcode, highlighting its seamless integration with System.Drawing objects and its support for implicit casting. By the end of the tutorial, the program successfully detects and prints the values of the barcodes and QR codes, with each value corresponding to the data encoded within. The tutorial concludes with an invitation to the audience to try out the software by downloading it from the website.
