### Create a ZIP Archive

Source: https://ironsoftware.com/csharp/zip/docs

Use the `using` statement and `AddArchiveEntry` to create a new ZIP file and add files to it. Save the archive using `SaveAs`.

```csharp
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");
        }
    }
}
```

```vbnet
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

```

### Add Files to Existing Archive

Source: https://ironsoftware.com/csharp/zip/docs

Open an existing ZIP file by passing its path to the constructor. Use `AddArchiveEntry` to add new files and `SaveAs` to persist the changes.

```csharp
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");
        }
    }
}
```

```vbnet
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

Extract the contents of a ZIP file to a specified directory using `ExtractArchiveToDirectory`. Ensure the ZIP file path and extraction path are correctly set.

{
    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);
        }
    }
}
```

```vbnet
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/"

	End Sub
End Class
