How to Print a Barcode in ASP .NET

In this tutorial, we delve into the process of printing barcodes in an ASP.NET web application using the Iron Barcode library. The demonstration utilizes Visual Studio 2022 and the Iron Barcode library, which can be installed via the NuGet Package Manager. We start by accessing the barcode model in the barcodeModel.cs file, where a public class contains properties for file name and barcode content. This model is then used in the barcodeController.cs file, which manages the creation and display of barcodes. The createBarcode method uses the Iron Barcode library to generate a JPEG file of the barcode, handling exceptions by redirecting users to a retry view if needed. In the createbarcode.cshtml file, users input details to generate the barcode, and upon clicking 'Create', the server processes this data to output a barcode image. Any issues redirect users back to the input view. This tutorial highlights Iron Barcode's effectiveness and ease of use in ASP.NET applications, making it an essential tool for developers.
