.NET Barcode Code 128 Generator Introduction
Top
Generating Barcode Code 128 in .NET is one of the functions in OnBarcode's
.NET Barcode Generators, which supports creating & printing Code-128 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:
.NET Code 128 Generator - Barcode Code-128 Introduction
 |
Code 128, also known as ANSI/AIM 128, ANSI/AIM Code 128, USS Code 128, Uniform Symbology Specification Code 128, is a very high-density barcode symbology. (A special version of it called GS1-128 is used extensively world wide in shipping and packaging industries.) It is used for alphanumeric or numeric-only barcodes. |
.NET Code 128 Generation - Code-128 Valid Data Scope
.NET Code 128 Generator encodes:
- all 128 characters of ASCII
- values 128-255 in accordance with ISO 8859-1. There are referred to as extended ASCII.
How to Generate & Print Code-128 in Visual Studio C# or VB.NET Class?

Generating barcode Code-128 in
C# Class example (
C# Code 128 Generator Complete Demo Source Code):
Linear code128 = new Linear();
code128.Type = BarcodeType.CODE128;
code128.Data = "0123456789";
code128.X = 1;
code128.Y = 60;
// Generate Code-128 and encode barcode to gif format
code128.Format = System.Drawing.Imaging.ImageFormat.Gif;

// Print Code 128 C# Bitmap object
Bitmap code128Bitmap = code128.drawBarcode();
Generating barcode Code-128 in
VB.NET Class example (
VB.NET Code 128 Generator Complete Demo Source Code):
Dim code128 As OnBarcode.Barcode.Linear
code128 = New OnBarcode.Barcode.Linear()
code128.Type = OnBarcode.Barcode.BarcodeType.CODE128
code128.Data = "0123456789"
code128.X = 1
code128.Y = 60
' Generate Code-128 and encode barcode to png format
code128.Format = System.Drawing.Imaging.ImageFormat.Png
code128.drawBarcode("c:/vbnet-code128.png")
' Print Code-128 to vb.net Bitmap object
Dim code128Bitmap As Bitmap
code128Bitmap = code128.drawBarcode()
How to Create & Draw Code 128 Image in ASP.NET aspx or Html Pages Without ASP.NET Barcode Controller?
Top
- 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=CODE128&TYPE=7.
- To create barcode Code 128 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=CODE128&TYPE=7" />
How to Create & Encode Barcode Code 128 to Image File (GIF, JPEG, PNG, BMP)?
Top
Creating barcode Code-128 in C# Class example:
Linear code128 = new Linear();
code128.Type = BarcodeType.CODE128;
code128.Data = "0123456789";
code128.ShowText = true;
// Create Code-128 and encode barcode to Jpeg format
code128.Format = System.Drawing.Imaging.ImageFormat.Jpeg;
code128.drawBarcode("C://csharp-code128.jpg");
Creating barcode Code-128 in VB.NET Class example:

In Visual Studio C# & VB.NET, How to Draw & Print Barcode Code 128 to .NET Graphics, Stream & Bitmap Objects?
Top
To draw & print barcode Code-128 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 Code-128 to VB.NET objects:
