Update Built-In Properties in Presentations using .NET

Introduction

In this tutorial, we’ll delve into the powerful capabilities of GroupDocs.Metadata for .NET, a comprehensive library designed to manipulate metadata within documents using the .NET framework. Specifically, we’ll focus on updating built-in properties in presentations (.PPT and .PPTX files) programmatically using C#.

Prerequisites

Before we begin, ensure you have the following:

• Visual Studio: Installed on your system.
• GroupDocs.Metadata for .NET: Downloaded and installed from here.
• Basic C# Knowledge: Familiarity with C# programming language.

Import Namespaces

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

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

Step 1: Load the Presentation File

First, create a new instance of Metadata by loading your presentation file:

using (Metadata metadata = new Metadata("YourPresentationFile.pptx"))
{
    var root = metadata.GetRootPackage<PresentationRootPackage>();

Step 2: Update Built-In Properties

Now, update the desired built-in properties of the presentation. For example, you can modify the author, creation date, company, category, keywords, etc. Here’s how you can do it:

root.DocumentProperties.Author = "YourAuthorName";
root.DocumentProperties.CreatedTime = DateTime.Now;
root.DocumentProperties.Company = "YourCompany";
root.DocumentProperties.Category = "YourCategory";
root.DocumentProperties.Keywords = "metadata, presentation, update";

Step 3: Save Changes

After updating the properties, save the changes back to the presentation file:

metadata.Save("YourPresentationFile.pptx");

Conclusion

In this tutorial, we explored how to use GroupDocs.Metadata for .NET to update built-in properties in presentation files programmatically. By following these steps, you can efficiently manage and modify metadata within your .NET applications.
