Prerequisites

Before moving on to the implementation, ensure the following prerequisites are in place:

1. Visual Studio: Install Visual Studio, the comprehensive integrated development environment for building .NET C# applications. If not installed, you can download it from its official website.
2. IronZIP Package: Use NuGet Package Manager to install the IronZIP library for your project.

Steps to Create a ZipArchive File System in .NET

Step 1 Create a C# Console Project in Visual Studio

• Open Visual Studio and create a new C# console project.

• Configure the project name and location.

  

• Choose the appropriate .NET version based on your project requirements. IronZIP supports the latest version and older versions of .NET and .NET core, so you can choose any version from the available list.

  

Step 2 Installing IronZIP using NuGet Package Manager

Integrating IronZIP into the project is a very straightforward process. You can install the IronZIP library as so:

Open the Manage NuGet Packages for Solution by right-clicking the Solution Explorer.

In the NuGet browse tab, search for IronZIP and click install.

Alternatively, you use the NuGet Package Manager Console and run the command:

Install-Package IronZip

That's it! We have set up everything, and we can proceed to create Zip files in our application.

Step 3 Creating a .NET ZipArchive File Stream

1. Import IronZIP Namespace

First, we need to include the IronZIP namespace in our source code main file by using the statement:

using IronZIP;

using IronZIP;

Imports IronZIP

2. Create a Zip File

Creating a zip file becomes remarkably easy with IronZIP, thanks to its user-friendly API and straightforward syntax. Follow these steps to create a C# zip archive file system

Code Example:

class Program
{
    public static void Main(string[] args)
    {
    var file = "output.zip";
        // Create an empty ZIP archive
        using (var archive = new IronArchive(file))
        {
            // Add files to the ZIP
            archive.AddArchiveEntry("./assets/image1.jpg");
            archive.AddArchiveEntry("./assets/image2.jpg");
            archive.AddArchiveEntry("./assets/image3.jpg");
        }
        Console.WriteLine("Zip file generated successfully!");
    }
}

class Program
{
    public static void Main(string[] args)
    {
    var file = "output.zip";
        // Create an empty ZIP archive
        using (var archive = new IronArchive(file))
        {
            // Add files to the ZIP
            archive.AddArchiveEntry("./assets/image1.jpg");
            archive.AddArchiveEntry("./assets/image2.jpg");
            archive.AddArchiveEntry("./assets/image3.jpg");
        }
        Console.WriteLine("Zip file generated successfully!");
    }
}

Friend Class Program
	Public Shared Sub Main(ByVal args() As String)
	Dim file = "output.zip"
		' Create an empty ZIP archive
		Using archive = New IronArchive(file)
			' Add files to the ZIP
			archive.AddArchiveEntry("./assets/image1.jpg")
			archive.AddArchiveEntry("./assets/image2.jpg")
			archive.AddArchiveEntry("./assets/image3.jpg")
		End Using
		Console.WriteLine("Zip file generated successfully!")
	End Sub
End Class

Explanation:

• The using statement ensures proper management of the IronArchive object, releasing resources when the block is exited.
• The IronArchive constructor takes in a string parameter, which represents the path and name of the entire zip file to be created.
• The AddArchiveEntry method is employed to include three image files as entries in the zip archive. Adjust file paths based on your file locations.

3. Extract Zip File Content

Extracting the archive contents from zip files with an application is another handy feature to have. IronZIP with its one-line code helps to extract data from the ZipArchive archive file system effortlessly. Write the sample code to achieve this task:

using IronZIP;
// Extract ZIP
IronArchive.ExtractArchiveToDirectory("output.zip", "extracted");

using IronZIP;
// Extract ZIP
IronArchive.ExtractArchiveToDirectory("output.zip", "extracted");

Imports IronZIP
' Extract ZIP
IronArchive.ExtractArchiveToDirectory("output.zip", "extracted")

That's it! Zip file extracted. IronZIP also offers aid with adding files to the existing file system of ZipArchive. For more detailed information please visit this tutorial on create, read, and extract Zip on the IronZIP website.

Step 4 Execute the Program to Get the New ZipArchive

Build and run the Zip archive application. After successful execution, check your project directory with the specified entry name in the program for the resulting Zip file: "output.zip" containing the specified image files. Here is the output Zip file content-disposition:

Conclusion

In conclusion, IronZIP emerges as a powerful and versatile solution for handling zip archives in C#. Its cross-platform support, compatibility with various .NET versions, and straightforward integration make it a valuable tool for developers.

IronZIP simplifies the creation, reading, and extraction of zip archives in your C# projects and enhances the efficiency of file management processes.
