In this tutorial, learn how to generate barcode images using C# and the Iron Barcode library. Begin by opening Visual Studio and accessing the package manager console. Install the barcode library using the command install package barcode. Once installed, navigate to the program.cs file to write your code. Import the namespace using IronBarcode and use BarcodeWriter.CreateBarcode() to generate the barcode, specifying the text to encode. For this example, the text is 'This is my first barcode by Iron Barcode'. Use the encoding scheme BarcodeEncoding.Code128. Save the barcode as an image file, choosing from formats like PNG, JPEG, and PDF. Here, we save it as 'barcode.png'. Run the project to generate the image, which can be found in the bin folder. To add value text below the barcode, use barcode.AddBarcodeValueTextBelowBarcode(). Run the program again to see the updated barcode image with text. If questions arise, contact our support team for assistance.
