Generating Barcode EAN-8 in .NET is one of the functions in OnBarcode's .NET Barcode Generators, which supports creating & printing EAN-8 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 EAN-8 Generator - Barcode EAN-8 Introduction

EAN-8 is a linear barcode and is derived from the longer European Article Number (EAN-13) code. It was introduced for use on small packages where an EAN-13 barcode would be too large.

 

.NET EAN-8 Generation - EAN-8 Valid Data Scope

.NET EAN 8 Generator encodes:

• 0, 1, 2, 3, 4, 5, 6, 7, 8, 9

 

Generating barcode EAN-8 in C# Class example (C# Source Code to Create EAN-8 barcodes)

	        Linear ean8 = new Linear();
	        ean8.Type = BarcodeType.EAN8;
	        ean8.Data = "1234567";
	        ean8.X = 1;
	        ean8.Y = 60;
	        
	        // Generate EAN-8 and encode barcode to gif format
	        ean8.Format = ImageFormat.Gif;
	        ean8.drawBarcode("c#-ean8.gif");
	        
	        // Print EAN-8 to C# Bitmap object
	        Bitmap ean8Bitmap = ean8.drawBarcode();

Generating barcode EAN-8 in VB.NET Class example

	        Dim ean8 As OnBarcode.Barcode.Linear
	        ean8 = New OnBarcode.Barcode.Linear()
	        ean8.Type = OnBarcode.Barcode.BarcodeType.EAN8
	        ean8.Data = "1234567"
	        ean8.X = 1
	        ean8.Y = 60
	        
	        // Generate EAN-8 and encode barcode to png format
	        ean8.Format = ImageFormat.Png
	        ean8.drawBarcode("vbnet-ean8.png")
	        
	        // Print EAN-8 to vb.net Bitmap object
	        Dim ean8Bitmap As Bitmap
	        ean8Bitmap = ean8.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/linear.aspx?DATA=1234567&TYPE=12
  
  
• To create barcode EAN-8 image in html or aspx pages, you can insert a image tag (img) into your page.
  For example, <img src="http://YourDomain:Port/barcode/linear.aspx?DATA=1234567&TYPE=12" />
  
  

 

Creating barcode EAN-8 image in C# Class example

	        Linear ean8 = new Linear();
	        ean8.Type = BarcodeType.EAN8;
	        ean8.Data = "1234567";
	        ean8.X = 1;
	        ean8.Y = 60;
	        
	        // Create EAN-8 and encode barcode to Jpeg format
	        ean8.Format = ImageFormat.Jpeg;
	        ean8.drawBarcode("C://csharp-ean8.jpg");

Creating barcode EAN-8 image in VB.NET Class example

	        Dim ean8 As OnBarcode.Barcode.Linear
	        ean8 = New OnBarcode.Barcode.Linear()
	        ean8.Type = OnBarcode.Barcode.BarcodeType.EAN8
	        ean8.Data = "1234567"
	        ean8.X = 1
	        ean8.Y = 60
	        
	        // Create EAN-8 and encode barcode to Jpeg format
	        ean8.Format = ImageFormat.Jpeg
	        ean8.drawBarcode("C://vbnet-ean8.jpg")

 

To draw & print barcode EAN-8 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 EAN-8 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)
