Guide Overview
It's easy to use BC.NetBarcodeGenerator.All2D library to generate and save 2d/matrix barcode symbologies in your .NET/C#/VB.NET Class, Console Application, .NET Windows Forms, and ASP.NET web projects. Please firstly download and get the free trial library of BC.NetBarcodeGenerator.All2D. And the only thing for integration is to add your project reference to the library dll.
Support QR Code, Data Matrix, and PDF417 barcode symbologies.
PLEASE NOTE, BC.NetBarcodeGenerator.All2D package only supports 2d barcode symbologies (QR Code, Data Matrix & PDF417) generation for .NET applications. To generate all linear/1d and 2d barcode symbologies, you should use BC.NetBarcodeGenerator.All SDK package.
On this page, we provide C# and VB.NET Class coding examples of how to use BC.NetBarcodeGenerator.All2D library to generate 2d barcodes (QR Code, Data Matrix & PDF417) to a local raster image file and Bitmap object. In addition, you can also output 2d barcodes to Stream, Graphics, and HttpResponse in .NET applications.
In addition to barcodes generation in .NET/C#/VB.NET Class, you can also generate 2D barcodes in .NET Windows Forms, ASP.NET Web Forms, and IIS applications in other ways. Please click to see details. Moreover, 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.
How to Generate 2D Barcodes in .NET Class
1. This section shows how to generate 2d barcode QR Code/Data Matrix/PDF417 to a local raster image file on your disk in ASP.NET C# and VB.NET Class. Jpg, Jpeg, Tiff, Png, Bmp, and Gif formats are supported. Please firstly add your ASP.NET project reference to BC.NetBarcodeGeneratorTrial.All2D.dll.
