Barcode in C#

Generate barcode in c# using itextsharp
Text is a PDF library that allows you to CREATE, ADAPT, INSPECT and MAINTAIN documents in the Portable Document Format (PDF):

• Generate documents and reports based on data from an XML file or a database
• Create maps and books, exploiting numerous interactive features available in PDF

Steps for creating barcodes.

• creating new project window application
• download itextsharp from Here
• add reference of itextSharp.dll to your project
• Add a button to form
• add the following code on button click
• use the following namespaces
