How Can I Programmatically Unzip Files in .NET Securely?

Unzipping Files Programmatically in .NET

Seeking a secure and reliable method to extract zipped files within your .NET application, consider the following approach:

Starting with .NET 4.5, you can leverage the native ZipFile class within the System.IO.Compression.FileSystem assembly. This class provides a convenient interface for both zipping and unzipping operations.

To unzip a file using ZipFile:

1. Add a DLL reference to the System.IO.Compression.FileSystem.dll assembly.
2. Utilize the ZipFile.ExtractToDirectory method, specifying the path to the zipped file and the desired extraction destination.

Here's an example demonstrating the process:

using System;
using System.IO;

namespace ConsoleApplication
{
    class Program
    {
        static void Main(string[] args)
        {
            // Define file paths
            string startPath = @"\path\to\source_directory";
            string zipPath = @"\path\to\result.zip";
            string extractPath = @"\path\to\extraction_directory";

            // Create a ZIP archive from the source directory
            System.IO.Compression.ZipFile.CreateFromDirectory(startPath, zipPath);

            // Extract the ZIP archive to the destination directory
            System.IO.Compression.ZipFile.ExtractToDirectory(zipPath, extractPath);
        }
    }
}

This approach offers a secure and efficient way to handle ZIP files without the need for external libraries or manual user intervention.
