Guide Overview
It's easy to use BC.NetBarcodeGenerator.All library to encode and generate barcode symbologies in your .NET/C#/VB.NET Class, Console Application, .NET WinForms, and ASP.NET web projects. Please firstly download and get the free trial library of BC.NetBarcodeGenerator.All. And the only thing for integration is to add your project reference to the library dll.
Support QR Code, Data Matrix, PDF417, Code 128, Code 39, EAN-13, EAN-8, GS1-128/EAN-128, UPC-A, UPC-E, Codabar, ITF-14, Planet, Postnet, OneCode/Intelligent Mail, and Interleaved 2 of 5 barcode symbologies.
We provide C# and VB.NET Class coding examples of how to use BC.NetBarcodeGenerator.All library to generate and encode 2d barcodes and 1d barcodes to a local raster image and Bitmap object. In addition, you can also generate and output 1d barcodes and 2d barcodes to Stream, Graphics, and HttpResponse in .NET Class Library, .NET Windows Forms, ASP.NET web, and .NET Console applications.
In addition to barcode generation in .NET Class, you can also generate 2D and 1D barcodes in .NET Windows Forms, ASP.NET Web Forms, and IIS applications in other ways. Please click to see more details.
PLEASE NOTE: ASP.NET web project and .NET Windows Forms project demos are included in our free trial package. Please download a free trial to see more.
Barcode Generation Examples in .NET Class
1. These coding examples show how to generate and output a 2D barcode QR Code to a local raster image file on your disk in ASP.NET C# & VB.NET Class. Jpg, Jpeg, Tiff, Png, Bmp, and Gif formats are supported. Please firstly add your ASP.NET project reference to BC.NetBarcodeGeneratorTrial.All.dll.
