Read Built-In Properties from Diagrams in .NET

Introduction

In this tutorial, we’ll delve into using GroupDocs.Metadata for .NET to read built-in properties from diagrams. GroupDocs.Metadata for .NET is a powerful library that enables developers to work with metadata associated with various document types, including diagrams, presentations, images, and more. Specifically, we’ll focus on extracting metadata properties from diagram files using this library.

Prerequisites

Before we begin, ensure you have the following prerequisites in place:

  • Basic knowledge of C# and .NET development.
  • Visual Studio IDE installed on your machine.
  • GroupDocs.Metadata for .NET library. You can download it from here.
  • An input diagram file (e.g., .vsdx) to extract metadata from.

Import Namespaces

Start by importing the necessary namespaces in your C# project to use GroupDocs.Metadata functionalities:

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

Step 1: Load the Diagram File

Begin by loading the diagram file from which you want to extract metadata:

using (Metadata metadata = new Metadata("YourDiagramFile.vsdx"))
{
    // Access the root package for diagrams
    var root = metadata.GetRootPackage<DiagramRootPackage>();
    // Now, you can access various document properties
    // Let's print some of the properties to the console
}

Step 2: Access Built-In Properties

Once the diagram file is loaded, you can access its built-in properties through DocumentProperties:

Console.WriteLine(root.DocumentProperties.Creator);
Console.WriteLine(root.DocumentProperties.Company);
Console.WriteLine(root.DocumentProperties.Keywords);
Console.WriteLine(root.DocumentProperties.Language);
Console.WriteLine(root.DocumentProperties.TimeCreated);
Console.WriteLine(root.DocumentProperties.Category);

Step 3: Utilize Other Metadata Information

Apart from DocumentProperties, GroupDocs.Metadata provides access to other metadata properties specific to diagram files. For instance, you can access layers, pages, shapes, and much more depending on the diagram type.

Conclusion

In this tutorial, we explored how to use GroupDocs.Metadata for .NET to read built-in properties from diagram files effortlessly. Leveraging this library, developers can efficiently manage and extract metadata associated with various document types in their .NET applications.
