Generating Barcode Data Matrix in .NET is one of the functions in OnBarcode's .NET Barcode Generators, which supports creating & printing Data Matrix and 30+ other linear & 2D bar codes for C#, VB.NET & ASP.NET applications.

OnBarcode develops several .NET Barcode Generation components for different .NET development environments:

Barcode Generation in ASP.NET - Creating barcodes in ASP.NET Web applications
Barcode Generation in Windows Forms - Printing barcodes in C#, VB.NET Windows Forms applications
Barcode Generation in Reporting Service - Drawing barcodes in Microsoft Reporting Service 2005 & 2008

 

.NET Data Matrix Generator - Barcode Data Matrix Introduction

Data Matrix is a two-dimensional matrix barcode consisting of black and white "cells" or modules arranged in either a square or rectangular pattern. The information to be encoded can be text or raw data. Usual data size is from a few bytes up to 2 kilobytes. The length of the encoded data depends on the symbol dimension used. Error correction codes are added to increase symbol strength: even if they are partially damaged, they can still be read. A Data Matrix symbol can store up to 2,335 alphanumeric characters.

 

.NET Data Matrix Generation - Data Matrix Valid Data Scope

.NET Data Matrix Generator encodes:

• all 128 characters of ASCII
  
  
• values 128-255 in accordance with ISO 8859-1. There are referred to as extended ASCII.

 

Generating barcode Data Matrix in C# Class example (C# Source Code to Create Data Matrix barcodes)

	        DataMatrix datamatrix = new DataMatrix();
	        datamatrix.Data = "0123456789";
	        datamatrix.X = 3;
	        
	        // Generate Data Matrix and encode barcode to gif format
	        datamatrix.Format = ImageFormat.Gif;
	        datamatrix.drawBarcode("c#-datamatrix.gif");
	        
	        // Print Data Matrix to C# Bitmap object
	        Bitmap datamatrixBitmap = datamatrix.drawBarcode();

Generating barcode Data Matrix in VB.NET Class example

	        Dim datamatrix As OnBarcode.Barcode.DataMatrix
	        datamatrix = New OnBarcode.Barcode.DataMatrix()
	        datamatrix.Data = "0123456789"
	        datamatrix.X = 3
	        
	        // Generate Data Matrix and encode barcode to png format
	        datamatrix.Format = ImageFormat.Png
	        datamatrix.drawBarcode("vbnet-datamatrix.png")
	        
	        // Print Data Matrix to vb.net Bitmap object
	        Dim datamatrixBitmap As Bitmap
	        datamatrixBitmap = datamatrix.drawBarcode();

 

• Under demo package, copy barcode folder and its contents to your IIS, and create a new virtual directory.
  
  
• Restart IIS, navigate to http://YourDomain:Port/barcode/datamatrix.aspx?DATA=0123456789
  
  
• To create barcode Data Matrix image in html or aspx pages, you can insert a image tag (img) into your page.
  For example, <img src="http://YourDomain:Port/barcode/datamatrix.aspx?DATA=0123456789" />

	        datamatrix.drawBarcode("C://vbnet-datamatrix.jpg")

 

To draw & print barcode Data Matrix to C# objects:

	        public void drawBarcode(Graphics graphics);
	
	        public void drawBarcode(string filename);
	
	        public Bitmap drawBarcode();
	
	        public void drawBarcode(Stream fileStream);

To draw & print barcode Data Matrix to VB.NET objects:

	        Public Sub drawBarcode(ByRef graphics As Graphics)
	
	        Public Sub drawBarcode(ByVal filename As String)
	
	        Public Function drawBarcode() As Bitmap
	
	        Public Sub drawBarcode(ByRef fileStream As Stream)
