C# Tutorial: Create, Read & Extract ZIP Files
Create ZIP generates a new ZIP archive by selecting files or directories, specifying compression settings, and creating the archive.
Extract ZIP retrieves contents by specifying the source ZIP file, the destination folder, and extracting files and directories to the specified location.
In addition to these functions, IronZIP can also open an existing ZIP file, add more files to it, and then export the result as a new ZIP file containing all the included files.
Quickstart: Create or Extract a ZIP with IronZIP EasilyGet started fast - create, modify, or extract ZIP archives using IronZIP in just a few simple API calls. Perfect for developers who want to instantly work with archives without boilerplate.

Minimal Workflow (5 steps)
- Download the C# library to create, read, and extract ZIP files
- Instantiate the IronZipArchive class to create an empty ZIP file
- Use the
Addmethod to add files to the empty ZIP - Utilize the
ExtractArchiveToDirectorymethod to extract the ZIP - Open an existing ZIP file by passing the ZIP file path to the constructor
Create an Archive Example
To create a ZIP archive object, you can conveniently use the using statement in C# along with the IronZipArchive constructor. IronZIP makes this process straightforward, allowing you to establish an empty ZIP archive with just a few lines of code.
Next, utilize the Add method to import your files into the ZIP archive. This method adds a single file at a time; call it once per file you want to include.
Lastly, use the SaveAs method to export the ZIP file.
using IronZip;
// Create an empty ZIP
using (var archive = new IronZipArchive())
{
// Add files to the ZIP
archive.Add("./assets/image1.png");
archive.Add("./assets/image2.png");
// Export the ZIP file
archive.SaveAs("output.zip");
}Imports IronZip
' Create an empty ZIP
Using archive = New IronZipArchive()
' Add files to the ZIP
archive.Add("./assets/image1.png")
archive.Add("./assets/image2.png")
' Export the ZIP file
archive.SaveAs("output.zip")
End UsingUnarchive an Archive to Folder
To retrieve the contents from a ZIP file, you can use the ExtractArchiveToDirectory method. Simply indicate the path of the target ZIP file and the directory where you want the extracted files to be placed.
using IronZip;
// Extract ZIP
IronZipArchive.ExtractArchiveToDirectory("output.zip", "extracted");Imports IronZip
' Extract ZIP
IronZipArchive.ExtractArchiveToDirectory("output.zip", "extracted")Add Files to An Existing Archive
You can efficiently modify an existing ZIP archive with additional files using IronZIP. The process begins by instantiating the ZIP archive object from an existing ZIP file path. Once the archive is opened, you can use the Add method to add files to the existing archive.
using IronZip;
// Open existing ZIP
using (var archive = new IronZipArchive("existing.zip"))
{
// Add files
archive.Add("./assets/image3.png");
archive.Add("./assets/image4.png");
// Export the ZIP file
archive.SaveAs("result.zip");
}Imports IronZip
' Open existing ZIP
Using archive = New IronZipArchive("existing.zip")
' Add files
archive.Add("./assets/image3.png")
archive.Add("./assets/image4.png")
' Export the ZIP file
archive.SaveAs("result.zip")
End UsingWith this functionality, you can efficiently update and expand your ZIP archives to suit your project's evolving needs. IronZIP makes the process of managing archives in your C# projects a breeze.
A similar approach can be achieved for other archive and compression formats such as TAR, GZIP, and BZIP2 using the IronTarArchive, IronGZipArchive, and IronBZip2Archive classes, respectively.
