Create, Print barcode images in C#/VBNET ASP.NET Core application with free source code
In this C# guide page, you will learn how to generate, encode barcode images in .NET Core projects.
How to create barcodes in ASP.NET Core and Windows application using C#
Generating barcodes in C#.NET is an easy task with
OnBarcode .NET Core Barcode Generator Components.
OnBarcode provides various barcode libraries and controls for generating barcodes using Microsoft Visual C#.NET on ASP.NET, C# Class,
Windows software, Console applications, and .NET Reporting projects.
You can also use our .NET Core Barcode Reader SDK to
read and scan barcodes in C#/VB.NET Core projects.
This article helps you to choose the right barcode generation component for integration in your C#/VB.NET Core applications.
Generate barcodes in various .NET Core development environments Top
Barcode Generator for .NET Core dlls are built based on .NET Standard 2.0. And they are supporting the following .NET implementation
You can easiy create 2d and linear barcode images in your .NET Core and .NET Framework projects.
Compare .NET Core Barcode Generator versions (System.Drawing.Common vs SkiaSharp)TopWhy need two Barcode Generator dlls
In .NET Core Barcode Generator dlls folder, there are two dlls, OnBarcode.Barcode.Common.dll and OnBarcode.Barcode.Common.Skia.dll.
Both of them are built using .NET Standard 2.0 and support all most the same barcode generation features in .NET 7, 6, 5.
The differences between two dlls
Both of the two dlls support generating ISO standard barcodes with rich API on .NET Core.
C# .NET Core Barcode Generator Quick Start Top1. How to install .NET Barcode Generator Control to your Visual C# .NET Core project?
Add OnBarcode.Barcode.Common.dll to your C# or VB.NET project reference. 2. How to create linear barcodes in C# .NET Core class?
// Create linear barcode object
Linear barcode = new Linear();
// Set barcode symbology type to Code-39
barcode.Type = BarcodeType.CODE39;
// Set barcode data to encode
barcode.Data = "0123456789";
// Set barcode bar width (X dimension) in pixel
barcode.X = 1;
// Set barcode bar height (Y dimension) in pixel
barcode.Y = 60;
// Draw & print generated barcode to png image file
barcode.drawBarcode("C://csharp-code39.png");
 3. How to draw & print QR-Code in C# .NET Core class?
// Create QRCode object
QRCode qrCode = new QRCode();
// Set QR Code data to encode
qrCode.Data = "VB.NET QRCode";
// Set QRCode data mode (QR-Code Barcode Settings)
qrCode.DataMode = QRCodeDataMode.Auto;
// Draw & print generated QR Code to jpeg image file
qrCode.ImageFormat = System.Drawing.Imaging.ImageFormat.Jpeg;
qrCode.drawBarcode("C://csharp-qrcode.jpg");4. How to create & print Data Matrix in C# .NET Core class?
DataMatrix datamatrix = new DataMatrix();
// Create Data Matrix object
datamatrix.Data = "VB.NET DataMatrix";
// Set Data Matrix data to encode
datamatrix.DataMode = DataMatrixDataMode.ASCII;
// Set the data mode (Data Matrix Barcode Settings)
// Draw and print created Data Matrix to gif image file
datamatrix.ImageFormat = System.Drawing.Imaging.ImageFormat.Gif;
datamatrix.drawBarcode("C://csharp-data-matrix.gif");5. How to create & print PDF-417 in C# .NET Core class?
// Create PDF417 object
PDF417 pdf417 = new PDF417();
// Set Data Matrix data to encode
pdf417.Data = "PDF-417";
// Set PDF-417 data mode (PDF-417 Barcode Settings)
pdf417.DataMode = PDF417DataMode.Auto;
// Set PDF-417 number of rows
pdf417.RowCount = 3;
// Set PDF-417 number of columns
pdf417.ColumnCount = 5;
// Draw and print generated PDF417 to gif image file
pdf417.ImageFormat = System.Drawing.Imaging.ImageFormat.Gif;
pdf417.drawBarcode("C://csharp-pdf417.gif");6. In C# .NET Core Barcode Generator, how to print & encode barcodes to GIF, JPEG, PNG & BMP?
// Create linear barcode object
Linear barcode = new Linear();
// Set barcode symbology type to Code-39
barcode.Type = OnBarcode.Barcode.BarcodeType.CODE39;
// Set barcode data to encode
barcode.Data = "0123456789";
// Encode barcodes to other image format, by change file extension
barcode.Format = System.Drawing.Imaging.ImageFormat.Gif;
barcode.drawBarcode("C://csharp-barcode-code39.gif");
