  1. Add .NET Barcode Generator DLL for WinForms to Toolbox.

    Setup a new .NET Windows Forms project, right-click Toolbox, select Choose Items..., and click Browse... to find OnBarcode.Barcode.WinForms.dll. Then, you may find four controls added to toolbox, namely LinearWinForm, DataMatrixWinForm, PDF417WinForm, and QRCodeWinForm.
  2. Drag DataMatrixWinForm and drop it to your windows form and a Data Matrix barcode will be printed on the form instantly.

    If you want to print other barcode types, please drag and drop respective control to your windows form. Among them, LinearWinForm will generate & print all 20+ linear barcodes including Codabar, Code 39, Code 128, EAN-8, EAN-13, EAN-128, Interleaved 2 of 5, ISBN, ISSN, UPC-A, UPC-E and so on.
  3. You can also add a textbox on the form for inputting barcode encoding message

Below are the steps for printing barcodes in C# Class with basic settings. For more barcoding properties or methods, such as alphanumeric string /character encoding, barcode size controlling through width and height, image color, file format of Png / Jpg / Gif / Bitmap, automatic check digit implementation for linear barcode, please go to C# guide page for reference.
  1. Add .NET WinForms Barcode Library DLL to your Windows C# project reference.
  2. Use OnBarcode.Barcode as the namespace and copy the following C# demo code your C#.NET class panel. Let's take Data Matrix as an example.
   // Create a .NET WinForms Data Matrix object
DataMatrix datamatrix = new DataMatrix();

// Set Data Matrix encoded data
datamatrix.Data = ".NET WinForms C# Data Matrix";

// Set Data Matrix data mode
datamatrix.DataMode = DataMatrixDataMode.Auto;

// Set Data Matrix barcode image size
datamatrix.X = 3;
datamatrix.LeftMargin = 6;
datamatrix.RightMargin = 6;
datamatrix.TopMargin = 6;
datamatrix.BottomMargin = 6;

// Print Data Matrix to gif image file and save it to C:\
datamatrix.ImageFormat = System.Drawing.Imaging.ImageFormat.Gif;
datamatrix.drawBarcode("C://winfroms-csharp-datamatrix.gif");
