Prerequisites

Before you begin, ensure you have the following:

• Visual Studio: Integrated Development Environment (IDE) for .NET development.
• GroupDocs.Parser for .NET: Download the library from here.
• Knowledge of C#: Basic understanding of C# programming language.
• Sample PDF File: A PDF document to extract text from.

Import Namespaces

Start by importing the necessary namespaces into your C# code:

using System;
using System.Collections.Generic;
using System.IO;
using System.Text;
using GroupDocs.Parser.Data;
using GroupDocs.Parser.Options;

Step 1: Create an Instance of Parser Class

Instantiate the Parser class by providing the path to your sample PDF file.

// Create an instance of Parser class
using (Parser parser = new Parser("YourSampleFile.pdf"))
{
    // Your code here
}

Step 2: Get Document Info

Retrieve information about the PDF document using GetDocumentInfo() method.

// Get the document info
IDocumentInfo documentInfo = parser.GetDocumentInfo();

Step 3: Iterate Over Pages

Loop through each page of the document to select the specific page for text extraction.

// Iterate over pages
for (int p = 0; p < documentInfo.PageCount; p++)
{
    // Your code here
}

Step 4: Extract Text from the Page

Extract text from the desired page using GetText(int pageIndex) method.

// Extract a text into the reader
using (TextReader reader = parser.GetText(pageIndex))
{
    // Your code here
    string extractedText = reader.ReadToEnd();
    Console.WriteLine(extractedText); // Output the extracted text
}

Conclusion

You’ve now learned how to extract text from a specific page in a PDF file using GroupDocs.Parser for .NET. This process involves initializing the parser, retrieving document information, iterating over pages, and extracting text from the desired page. Incorporate these steps into your .NET application to handle PDF text extraction efficiently.
