IronZIP Library

To install the IronZIP package, use the following command in your terminal or package manager console:

Install-Package IronZip

Alternatively, download directly from the official IronZIP NuGet website.

Once installed, you can get started by adding using IronZip; to the top of your C# code.

Create an Archive Example

Create a ZIP file using the using statement. Inside the using block, use the AddArchiveEntry method to import files into the ZIP file. Finally, export the ZIP file with the SaveAs method.

using IronZip;
using System.IO;

class Program
{
    static void Main()
    {
        // Create a new ZIP file
        using (var archive = new ZipArchive())
        {
            // Add a file to the archive
            archive.AddArchiveEntry("example.txt", File.ReadAllBytes("path/to/example.txt"));

            // Save the ZIP archive
            archive.SaveAs("archive.zip");
        }
    }
}

using IronZip;
using System.IO;

class Program
{
    static void Main()
    {
        // Create a new ZIP file
        using (var archive = new ZipArchive())
        {
            // Add a file to the archive
            archive.AddArchiveEntry("example.txt", File.ReadAllBytes("path/to/example.txt"));

            // Save the ZIP archive
            archive.SaveAs("archive.zip");
        }
    }
}

Imports IronZip
Imports System.IO

Friend Class Program
	Shared Sub Main()
		' Create a new ZIP file
		Using archive = New ZipArchive()
			' Add a file to the archive
			archive.AddArchiveEntry("example.txt", File.ReadAllBytes("path/to/example.txt"))

			' Save the ZIP archive
			archive.SaveAs("archive.zip")
		End Using
	End Sub
End Class

Unarchive an Archive to Folder

Extract the content from the ZIP file using the ExtractArchiveToDirectory method. Specify the path of the target ZIP file and the extraction directory.

using IronZip;

class Program
{
    static void Main()
    {
        // path to the ZIP file and extraction directory
        string zipPath = "archive.zip";
        string extractPath = "extracted/";

        // Extract all files in the ZIP archive to the specified directory
        using (var archive = new ZipArchive(zipPath))
        {
            archive.ExtractArchiveToDirectory(extractPath);
        }
    }
}

using IronZip;

class Program
{
    static void Main()
    {
        // path to the ZIP file and extraction directory
        string zipPath = "archive.zip";
        string extractPath = "extracted/";

        // Extract all files in the ZIP archive to the specified directory
        using (var archive = new ZipArchive(zipPath))
        {
            archive.ExtractArchiveToDirectory(extractPath);
        }
    }
}

Imports IronZip

Friend Class Program
	Shared Sub Main()
		' path to the ZIP file and extraction directory
		Dim zipPath As String = "archive.zip"
		Dim extractPath As String = "extracted/"

		' Extract all files in the ZIP archive to the specified directory
		Using archive = New ZipArchive(zipPath)
			archive.ExtractArchiveToDirectory(extractPath)
		End Using
	End Sub
End Class

Add Files to An Existing Archive

Passing the ZIP file path to the constructor will open the ZIP file. Utilize the same AddArchiveEntry method to add files to the opened ZIP and export it with the SaveAs method.

using IronZip;
using System.IO;

class Program
{
    static void Main()
    {
        // Open an existing ZIP file
        using (var archive = new ZipArchive("archive.zip"))
        {
            // Add more files to the archive
            archive.AddArchiveEntry("anotherfile.txt", File.ReadAllBytes("path/to/anotherfile.txt"));

            // Save updates to the ZIP archive
            archive.SaveAs("archive.zip");
        }
    }
}

using IronZip;
using System.IO;

class Program
{
    static void Main()
    {
        // Open an existing ZIP file
        using (var archive = new ZipArchive("archive.zip"))
        {
            // Add more files to the archive
            archive.AddArchiveEntry("anotherfile.txt", File.ReadAllBytes("path/to/anotherfile.txt"));

            // Save updates to the ZIP archive
            archive.SaveAs("archive.zip");
        }
    }
}

Imports IronZip
Imports System.IO

Friend Class Program
	Shared Sub Main()
		' Open an existing ZIP file
		Using archive = New ZipArchive("archive.zip")
			' Add more files to the archive
			archive.AddArchiveEntry("anotherfile.txt", File.ReadAllBytes("path/to/anotherfile.txt"))

			' Save updates to the ZIP archive
			archive.SaveAs("archive.zip")
		End Using
	End Sub
End Class
