Guide Overview
It's easy to use BC.NetBarcodeGenerator.Upca library to draw and generate Upca 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.Upca. And the only thing for integration is to add your project reference to the library dll.
PLEASE NOTE, BC.NetBarcodeGenerator.Upca package only supports 1d/linear symbology UPC-A generation for .NET applications. For all barcode symbologies, we provide BC.NetBarcodeGenerator.All that supports the most popular linear barcodes and 2d barcodes.
On this page, we provide C# and VB.NET Class coding examples of how to use BC.NetBarcodeGenerator.Upca library to generate UPC-A and save barcodes to a local raster image file and Bitmap object. In addition, you can also save UPC-A barcodes to Stream, Graphics, and HttpResponse in .NET applications.
In addition to generating barcodes in .NET Class, you can also generate UPC-A 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.
Generating UPC-A in .NET/C#/VB.NET Class
1. This section shows how to generate UPC-A barcode 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.Upca.dll.
