How to Unzip a Zip File in C#

This tutorial will discuss the method to unzip a file in C#.

Unzip a File With the ZipFile.ExtractToDirectory() Function in C#

The ZipFile class is used to create, open and extract zip files in C#. The Zipfile.ExtractToDirectory() method extracts a zip file from a specified source folder to a destination folder. We need first to install the package System.IO.Compression to use this method. The file extension needs to be .zip for this method to work properly.

using System;
using System.IO.Compression;

namespace unzip_file {
  class Program {
    static void Main(string[] args) {
      string zipFilePath = @"C:\File\milestone 19.zip";
      string extractionPath = @"C:\File";
      ZipFile.ExtractToDirectory(zipFilePath, extractionPath);
      Console.WriteLine("Extracted Successfully");
    }
  }
}

Output:

Extracted Successfully

In the above code, we extracted the zip file milestone 19.zip inside the path C:\File to the path C:\File with the ZipFile.ExtractToDirectory() function in C#.
