Prerequisites

Before you begin, ensure you have the following:

• Visual Studio installed on your machine.

• GroupDocs.Parser for .NET library installed. You can download it here.

Import Namespaces

First, import the necessary namespaces in your C# code:

using GroupDocs.Parser.Data;
using System;
using System.Collections.Generic;

Step 1: Create an Instance of Parser Class

Initialize an instance of the Parser class by providing the path to your sample document.

using (Parser parser = new Parser("YourSampleFile.pdf"))
{
    // Code goes here
}

Step 2: Check Barcodes Extraction Support

Verify if the document supports barcode extraction using GroupDocs.Parser.

if (!parser.Features.Barcodes)
{
    Console.WriteLine("Document doesn't support barcodes extraction.");
    return;
}

Step 3: Extract Barcodes from the Document

Extract barcodes from the document using the GetBarcodes() method.

IEnumerable<PageBarcodeArea> barcodes = parser.GetBarcodes();

Step 4: Iterate Over Extracted Barcodes

Loop through the extracted barcodes to access each barcode’s details such as page index and value.

foreach (PageBarcodeArea barcode in barcodes)
{
    Console.WriteLine("Page: " + barcode.Page.Index.ToString());
    Console.WriteLine("Value: " + barcode.Value);
}
