Read Native Metadata Properties from 7Zip Archives in .NET

Introduction

In the realm of .NET development, managing metadata—such as document properties, file information, and tags—is crucial for efficient data organization and retrieval. GroupDocs.Metadata for .NET provides a powerful toolkit for accessing and manipulating metadata within various file formats. This tutorial focuses on harnessing the capabilities of GroupDocs.Metadata to read native metadata properties from 7Zip archives in .NET.

Prerequisites

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

• Visual Studio installed on your machine.
• Basic understanding of C# programming language.
• GroupDocs.Metadata for .NET library downloaded and referenced in your project.

Import Namespaces

Start by importing the necessary namespaces for utilizing GroupDocs.Metadata within your C# project.

using GroupDocs.Metadata.Common;
using GroupDocs.Metadata.Options;
using GroupDocs.Formats.Archive;
using System;
using GroupDocs.Metadata;
using System.Text;

Step 1: Load the 7Zip Archive

Begin by loading the 7Zip archive file into a Metadata object from GroupDocs.Metadata.

using (Metadata metadata = new Metadata("YourZipFile.zip"))
{
    // Code to read metadata will go here
}

Step 2: Access 7Zip Metadata Properties

Inside the using block, retrieve the root package of the 7Zip archive to access its properties.

var root = metadata.GetRootPackage<SevenZipRootPackage>();

Step 3: Display Total Entries

Retrieve and display the total number of entries (files and directories) within the 7Zip archive.

Console.WriteLine(root.SevenZipPackage.TotalEntries);

Step 4: Iterate Through Files

Iterate through each file in the 7Zip archive to access individual file metadata.

foreach (var file in root.SevenZipPackage.Files)
{
    Console.WriteLine(file.Name);
    Console.WriteLine(file.CompressedSize);
    Console.WriteLine(file.ModificationDateTime);
    Console.WriteLine(file.UncompressedSize);
}

Conclusion

In this tutorial, we explored how to utilize GroupDocs.Metadata for .NET to read native metadata properties from 7Zip archives. By following these steps, you can effectively extract and utilize metadata information embedded within your archive files, enhancing your .NET applications’ capabilities.
