Create a new ASP.NET Web Application Project.
Add a new Class to the project and Add Reference.

Add a new item (Class), named "SampleClass.cs" to the project.
Add "BarcodeLib.Barcode.RDLCReports.dll" to the project reference.
Add the following sample code to your created class "APP_Code/SampleClass.cs".
In Visual Studio menu bar, choose "Build Web Site" from "Build" tab.

     using System.Collections.Generic;
     using BarcodeLib.Barcode.RDLCReports;
     using BarcodeLib.Barcode;


     public class SampleClass
     {
         private string m_description;
         private int m_price;
         private byte[] m_bytes;

         public SampleClass(string description, int price, string data)
         {
             m_description = description;
             m_price = price;
             LinearRDLC barcode = new LinearRDLC();
             barcode.Type = BarcodeType.CODE128;
             barcode.Data = data;

             barcode.LeftMargin = 0;
             barcode.RightMargin = 0;
             barcode.TopMargin = 0;
             barcode.BottomMargin = 0;
        
             // more barcode settings here

             m_bytes = barcode.drawBarcodeAsBytes();
         }

         public byte[] Bytes
         {
             get { return m_bytes; }
         }

         public string Description
         {
             get
             {
                 return m_description;
             }
         }

         public int Price
         {
             get
             {
                 return m_price;
             }
         }
     }

     public class Merchant
     {
         private List<SampleClass> m_products;

         public Merchant()
         {
             m_products = new List<SampleClass>();
             m_products.Add(new SampleClass("code128", 25, "code128"));
             m_products.Add(new SampleClass("code39", 30, "code39"));
             m_products.Add(new SampleClass("qrcode", 15, "qrcode"));
         }

         public List<SampleClass> GetProducts()
         {
             return m_products;
         }
     }

BarcodeLib RDLC Report Barcode Generator also makes it easy to print barcodes in RDL Reports in .NET Windows applications using Visual C#. Below is a simplified tutorial, for more details, please view how to print barcodes in RDLC Report for .NET windows forms.

Create a new Windows Application Project.
Add a new DataSet to the project.
Add a new Report to the window form.
Add a Report Viewer to the window form.

Resize "Form1", and add "ReportViewer" to the form, with the default setting unchanged.
In "ReportViewer Tasks" window, choose your created report "BarcodeforRDLCReports.RDLCReports.rdlc".
Bind data collection: In Visual Studio menu bar, choose "Data Sources..." from "Report" tab.
Select "AdventureWorks.xsd_vProductAndDescription" as data sources. Click "Add to Report", then "OK" button.
Again, in "ReportViewer Tasks" window, choose "Rebind Data Sources".
Add "BarcodeLib.Barcode.RDLCReports.dll" to the project reference.
Add the following code to the "Form1.cs" file.

     using System.Data.OleDb;
     using System.Drawing.Imaging;
     using BarcodeLib.Barcode.RDLCReports;
     using BarcodeLib.Barcode;


     private void Form1_Load(object sender, EventArgs e)
     {
     // load data to the data table
     this.vProductAndDescriptionTableAdapter.Fill(this.AdventureWorks.vProductAndDescription);

     // create a linear barcode object
     LinearRDLC barcode = new LinearRDLC();

     // set barcode type to Code 128
     barcode.Type = BarcodeType.CODE128;

     // more barcode settings here

     // draw barcodes for each data row
     foreach (AdventureWorks.vProductAndDescriptionRow row in this.AdventureWorks.vProductAndDescription.Rows)
     {
     // set barcode encoding data value
     barcode.Data = row.ProductID.ToString();

     // set drawing barcode image format
     barcode.ImageFormat = System.Drawing.Imaging.ImageFormat.Png;

     row.Barcode = barcode.drawBarcodeAsBytes();
     }

     this.reportViewer1.RefreshReport();
     }
