Extract Text from PDFs with C# and Visual Studio 2019
Need to extract text from PDF documents programmatically in your C#/.NET applications? This guide walks you through converting PDF files to text using C# with Visual Studio 2019 and the WhatsMate PDF-to-Text REST API. Perfect for .NET developers, Windows application builders, and anyone who wants to automate PDF text extraction in their C#-based workflows.
Note for Visual Studio 2022 users: If you’re using Visual Studio 2022, please read this updated tutorial instead.
📋 Prerequisites
Before you begin, ensure you have:
- Basic C# knowledge - Familiarity with C# programming and .NET framework
- PDF URL - A publicly accessible URL to your PDF document
- Visual Studio 2019 - .NET development environment (or compatible IDE)
- System.Web.Extensions reference - Required for JSON serialization
ℹ️ Note: The trial account allows up to 20 PDF-to-Text API calls for learning purposes. Files up to 1 MB can use the synchronous API shown here. Subscribe to a Premium plan for production use and larger files.

📝 Step-by-Step Implementation
Follow these steps to extract text from a PDF using C#:
1. Copy the C# Code Template
Start by copying the following source code into your C# Console Application:
2. Configure the Parameters
Customize this key parameter in the script:
- Line 19: Replace with the URL of your PDF document
3. Add Required Reference
Ensure your project references System.Web.Extensions for JSON serialization:
- Right-click on your project in Solution Explorer
- Select Add Reference
- Find and check System.Web.Extensions under Framework
- Click OK
4. Run the Extraction
Build and run your C# application in Visual Studio to see the extracted text:
- Press F5 to build and run in debug mode
- Or use Ctrl+F5 to run without debugging
- Check the console output for the extracted text
⚠️ Large PDF files? If your PDF is larger than 1 MB, you’ll need to use the asynchronous API instead. See an example in C# for handling larger files.
🔧 Common Use Cases
This automation approach is ideal for:
- Data extraction pipelines - Pull text from reports, invoices, or forms
- Content indexing - Make PDF content searchable in your systems
- Batch processing - Extract text from multiple PDFs automatically
- Integration with workflows - Add PDF text extraction to .NET applications
