.NET Barcode Generator SDK

Create Barcode for ASP.NET Web
CnetSDK .NET Barcode Generator SDK includes mature linear/1d and matrix/2d barcodes creating & drawing features for ASP.NET web site page & web applications. This .NET barcode library component dll can be used to generate barcode images independently, without using other third-party .NET assemblies or components. You can use it to draw, create & make most commonly linear & 2d barcodes like Code 39, Code 128, EAN, UPC, and QR Code bar codes.
ASP.NET BARCODE CREATION & GENERATION OVERVIEW
This online tutorial page describes how to draw, generate, and create 1d & 2d barcode images in ASP.NET applications, like ASP.NET web page/site, IIS web application, and ASP.NET web class library. You can easily integrate mature linear & 2d barcodes generating and & creating features into your ASP.NET project. All bar codes are created compatible with latest ISO/IEC barcode specifications.

Please Note: a watermark ("www.cnetsdk.com") will be shown on each generated barcode image randomly if you are using .NET barcode generator trial.
USE ASP.NET BARCODE CREATOR CONTROL IN VS
The following steps illustrate how to draw, create & generate barcode image in Visual Studio ASP.NET project web form. CnetSDK .NET barcode creator library is used as a web form control.

1. Firstly, download free barcode generator trial online and you will find ASP.NET barcode creator control (CnetSDK.Barcode.Generator.Trial.dll) in the Lib folder;
2. Secondly, add this ASP.NET barcode maker & creator web form control to Visual Studio toolbox and you will see a control called "
CSWebControl" under toolbox;
      * Right click ".NET Visual Studio Toolbox", select menu "Choose Items... ";
      * In "Choose Toolbox Items" form, click button "Browse...", and select CnetSDK.Barcode.Generator.Trial.dll.
3. And then, with a project's web form open in design mode, drag and drop CnetSDK barcode creator & generator control item from toolbox onto the web form.
4. Finally, copy "CSWebHandler.ashx" file to your ASP.NET web site.    
USE ASP.NET BARCODE CREATOR CONTROL IN IIS
You can draw, create and generate barcode in IIS web application. Please do as follows.

1. Publish you APS.NET web site to your IIS.
2. Copy bin folder to your IIS. And copy "BarcodeWebHandler.ashx" file to your IIS root path.
3. Create an empty html web page, and add a sample Code 128 barcode using code 
4. Now, you can view html page on a web browser, and a sample Code 128 barcode will be displayed on the page.

Please Note: By using two ways above to draw and create barcode on web page, you should ensure that "BarcodeWebHandler.ashx" file is placed to the same folder as the web page. Moreover, the src property of tag can be set by javascript to customize barcode drawing & creating, and there is no need to refresh the whole web page.
USE .NET BARCODE CREATOR IN ASP.NET WEB CLASS
To integrate CnetSDK .NET Barcode Generator & Creator SDK, you may directly add CnetSDK.Barcode.Generator.Trial.dll to your ASP.NET web form project reference. And this barcode creator library DLL will be copied automatically to ASP.NET project bin folder.

And then, you can directly copy the following barcode creation C# sample code to your ASP.NET web from class, and draw & generate a sample Code 128 barcode.
using System;
using System.Web;
using System.Web.UI;
using CnetSDK.Barcode.Generator.Trial;

namespace ASPNETWebBarcodeGeneratorExample
{
    public partial class WebForm1 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            CSBarcode Code128 = new CSBarcode();
            Code128.BarcodeData = "www.cnetsdk.com";
            Code128.BarcodeType = CSBarcodeType.Code128;
            Code128.BarcodeWidth = 200;
            Code128.BarcodeHeight = 100;
            Code128.CreateBarcode("CScode128barcode.png");
        }
    }
}
Besides ASP.NET barcode generation guide, we also provide tutorial for .NET WinForms barcode making & generating.
