Reading Built-In Properties from PDFs in .NET

Introduction

In this tutorial, we’ll explore how to use GroupDocs.Metadata for .NET to read and manipulate metadata in PDF files. This powerful library allows developers to access various metadata attributes, such as the author, creation date, and subject, enhancing document management capabilities within applications.

Prerequisites

Before we begin, ensure you have the following:

  • Visual Studio: Make sure it’s installed on your system.
  • GroupDocs.Metadata for .NET: Download and install it from the official website.
  • Basic Knowledge of C#: Familiarity with C# and the .NET framework is recommended.

Import Namespaces

Start by including the necessary namespaces in your C# project:

using System;
using Formats.Document;

Step 1: Load PDF Metadata

To read metadata from a PDF file, load the document and extract its properties using the following code:

using (Metadata metadata = new Metadata("YourInputFile.pdf"))
{
    // Access the root package of the PDF file
    var root = metadata.GetRootPackage<PdfRootPackage>();
    
    // Retrieve and display built-in properties
    Console.WriteLine("Author: " + root.DocumentProperties.Author);
    Console.WriteLine("Created Date: " + root.DocumentProperties.CreatedDate);
    Console.WriteLine("Subject: " + root.DocumentProperties.Subject);
    Console.WriteLine("Producer: " + root.DocumentProperties.Producer);
    Console.WriteLine("Keywords: " + root.DocumentProperties.Keywords);
    // Access other properties as needed
}

With this straightforward approach, you can easily view essential metadata attributes embedded in your PDF files.
