Guide Overview
With simple integration, you can integrate high-quality barcodes generating features of BC.NetCoreBarcodeGenerator.All into your .NET Core projects development. This comprehensive .NET Core barcode generator library can be used to generate barcodes in C#/VB.NET Core Class Library, .NET Core ASP.NET Web, .NET Core Windows Forms, .NET Core Console App, and .NET Core Test Projects development.
Most popular barcode symbologies are supported, including 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.
2d & 1d barcodes can be encoded and output to raster images, Stream, Bitmap, Graphics, and HttpResponse in .NET Core projects. On this page, we provide C# and VB.NET coding examples of how to use BC.NetCoreBarcodeGenerator.All library to generate Code 39 and PDF417 to local raster images in .NET Core Console App. Certainly, you can also generate all supported 1d and 2d barcodes in other .NET Core projects.
PLEASE NOTE: the first character of the barcode will be recognized as "BC.Trial" for the trial package. A demo project is included in our free trial package. Please download a free trial to see more.
.NET Core Barcode Generating - C# & VB.NET Coding Examples
Here, we use the assembly "BC.NetCore21BarcodeGeneratorTrial.All.dll" which is for .NET Core 2.1. In all, four dlls are provided in the package and be used for .NET Core 2.1, 3.1, 5.0, and 6.0.
1. Create a new .NET Core Console App (.NET Core) project (Type: Visual C#); 2. Add your .NET Core project reference to the assembly "BC.NetCore21BarcodeGeneratorTrial.All.dll"; 3. "BC.NetCore21BarcodeGeneratorTrial.All.dll" relies on "System.Drawing.Common". So, "System.Drawing.Common" should be added. a. Choose "Manage NuGet Packages..." in the "Dependencies" menu to open the "NuGet Package Manager" tab; b. Choose "Browse" tab and search the NuGet package "System.Drawing.Common" in the Package source "nuget.org"; c. Install the System.Drawing.Common to your .NET Core project. 4. Then, try with the C# code and VB.NET code below.
