Remarks

Note

To use the ZipFile class in a .NET Framework app, you must add a reference to the System.IO.Compression.FileSystem assembly in your project. For information on how to add a reference to your project in Visual Studio, see How to: Add or Remove References.

The methods for manipulating zip archives and their files are spread across three classes: ZipFile, ZipArchive, and ZipArchiveEntry.

To...	Use...
Create a zip archive from a directory	ZipFile.CreateFromDirectory
Extract the contents of a zip archive to a directory	ZipFile.ExtractToDirectory
Add new files to an existing zip archive	ZipArchive.CreateEntry
Retrieve a file in a zip archive	ZipArchive.GetEntry
Retrieve all of the files in a zip archive	ZipArchive.Entries
To open a stream to an individual file contained in a zip archive	ZipArchiveEntry.Open
Delete a file from a zip archive	ZipArchiveEntry.Delete

Examples

This example shows how to create and extract a zip archive by using the ZipFile class. It compresses the contents of a folder into a zip archive, and then extracts that content to a new folder.

using System;
using System.IO.Compression;

class Program
{
    static void Main(string[] args)
    {
        string startPath = @".\start";
        string zipPath = @".\result.zip";
        string extractPath = @".\extract";

        ZipFile.CreateFromDirectory(startPath, zipPath);

        ZipFile.ExtractToDirectory(zipPath, extractPath);
    }
}

Imports System.IO.Compression

Module Module1

    Sub Main()
        Dim startPath As String = ".\start"
        Dim zipPath As String = ".\result.zip"
        Dim extractPath As String = ".\extract"

        ZipFile.CreateFromDirectory(startPath, zipPath)

        ZipFile.ExtractToDirectory(zipPath, extractPath)
    End Sub

End Module
