Read Built-In Properties from PDFs in .NET

Introduction

In this tutorial, we will explore how to leverage GroupDocs.Metadata for .NET to read built-in properties from PDF files. GroupDocs.Metadata is a powerful library that allows developers to work with metadata associated with various document formats, including PDFs, Microsoft Office documents, images, and more. By using this library, you can easily access and manipulate metadata attributes embedded within PDF files, such as author names, creation dates, subjects, and more.

Prerequisites

Before diving into this tutorial, ensure you have the following prerequisites:

  • Visual Studio: Make sure you have Visual Studio installed on your machine.
  • GroupDocs.Metadata for .NET: Download and install GroupDocs.Metadata for .NET from here.
  • Basic Knowledge of C#: Familiarity with C# programming language and .NET framework.

Import Namespaces

Begin by adding the necessary namespaces to your C# project:

using System;
using GroupDocs.Metadata;
using GroupDocs.Metadata.Formats.Document;

Step 1: Load PDF Metadata

First, load the PDF file and extract its metadata using GroupDocs.Metadata:

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);
    // Additional properties can be accessed similarly
    // ...
}

Beyond reading metadata, GroupDocs.Metadata allows for advanced operations like editing, removing, or adding new metadata properties to PDF files programmatically. This flexibility enables comprehensive management of document metadata within your .NET applications.
