Create GZIP

GZIP, short for 'GNU Zip,' is a file compression utility used in Unix and Linux systems. It reduces file sizes for efficient storage and faster transmission by utilizing the GZIP compression algorithm. Compressed files have a '.gz' extension and can be easily decompressed to their original state.

GZIP is commonly used for compressing individual files. It is also common practice to create compressed archives by gathering multiple files into a single TAR archive and then applying GZIP compression to that archive. The resulting file extensions would comprise both extensions, like the following: .tar.gz or .tgz.

Below is a conceptual example code snippet demonstrating how one might use a hypothetical IronGZipArchive class in C# to create a GZIP archive:

using System;

public class IronGZipArchive : IDisposable
{
    public void Add(string tarFile)
    {
        // Functionality to add a TAR file to be compressed
        Console.WriteLine($"Adding {tarFile} to the archive.");
    }

    public void SaveAs(string gzipFileName)
    {
        // Functionality to save the compressed file with .gz extension
        Console.WriteLine($"Saving the archive as {gzipFileName}.");
    }

    public void Dispose()
    {
        // Cleanup resources
        Console.WriteLine("Disposing resources.");
    }
}

class Program
{
    static void Main()
    {
        // Using statement ensures the IronGZipArchive resources are disposed properly
        using (IronGZipArchive archive = new IronGZipArchive())
        {
            // Add a TAR file to the GZIP archive
            archive.Add("myfiles.tar");

            // Save the GZIP archive with a .gz extension
            archive.SaveAs("myfiles.tar.gz");
        }
    }
}

using System;

public class IronGZipArchive : IDisposable
{
    public void Add(string tarFile)
    {
        // Functionality to add a TAR file to be compressed
        Console.WriteLine($"Adding {tarFile} to the archive.");
    }

    public void SaveAs(string gzipFileName)
    {
        // Functionality to save the compressed file with .gz extension
        Console.WriteLine($"Saving the archive as {gzipFileName}.");
    }

    public void Dispose()
    {
        // Cleanup resources
        Console.WriteLine("Disposing resources.");
    }
}

class Program
{
    static void Main()
    {
        // Using statement ensures the IronGZipArchive resources are disposed properly
        using (IronGZipArchive archive = new IronGZipArchive())
        {
            // Add a TAR file to the GZIP archive
            archive.Add("myfiles.tar");

            // Save the GZIP archive with a .gz extension
            archive.SaveAs("myfiles.tar.gz");
        }
    }
}

Imports System

Public Class IronGZipArchive
	Implements IDisposable

	Public Sub Add(ByVal tarFile As String)
		' Functionality to add a TAR file to be compressed
		Console.WriteLine($"Adding {tarFile} to the archive.")
	End Sub

	Public Sub SaveAs(ByVal gzipFileName As String)
		' Functionality to save the compressed file with .gz extension
		Console.WriteLine($"Saving the archive as {gzipFileName}.")
	End Sub

	Public Sub Dispose() Implements IDisposable.Dispose
		' Cleanup resources
		Console.WriteLine("Disposing resources.")
	End Sub
End Class

Friend Class Program
	Shared Sub Main()
		' Using statement ensures the IronGZipArchive resources are disposed properly
		Using archive As New IronGZipArchive()
			' Add a TAR file to the GZIP archive
			archive.Add("myfiles.tar")

			' Save the GZIP archive with a .gz extension
			archive.SaveAs("myfiles.tar.gz")
		End Using
	End Sub
End Class

Explanation:

• IronGZipArchive Class: This class hypothetical and illustrates compression processes. It implements IDisposable to ensure proper resource management.
• Add Method: Simulates adding a TAR file to the GZIP archive.
• SaveAs Method: Simulates saving the added file as a GZIP archive, with .gz extension.
• Dispose Method: Used to release resources used by the IronGZipArchive class.
• Using Statement: This is a C# construct that guarantees the proper disposal of resources once usage goes out of the scope (i.e., once the archive creation is done).
