public static class ZipFile

The ZipFile type exposes the following members.

  NameDescription
Public methodStatic memberCreateFromDirectory(String, String)Creates a zip archive that contains the files and directories from the specified directory.
Public methodStatic memberCreateFromDirectory(String, String, CompressionLevel, Boolean)Creates a zip archive that contains the files and directories from the specified directory, uses the specified compression level, and optionally includes the base directory.
Public methodStatic memberCreateFromDirectory(String, String, CompressionLevel, Boolean, Encoding)Creates a zip archive that contains the files and directories from the specified directory, uses the specified compression level and character encoding for entry names, and optionally includes the base directory.
Public methodStatic memberExtractToDirectory(String, String)Extracts all the files in the specified zip archive to a directory on the file system.
Public methodStatic memberExtractToDirectory(String, String, Encoding)Extracts all the files in the specified zip archive to a directory on the file system and uses the specified character encoding for entry names.
Public methodStatic memberOpen(String, ZipArchiveMode)Opens a zip archive at the specified path and in the specified mode.

The ZipFile class provides convenient static methods for working with zip archives. To use these methods, you must reference the System.IO.Compression.FileSystem assembly in your project. The System.IO.Compression.FileSystem assembly is not available for Windows Store apps. Therefore, the ZipFile class and ZipFileExtensions class (which is also in the System.IO.Compression.FileSystem assembly) are not available in Windows Store apps. In Windows Store apps, you work with compressed files by using the methods in the ZipArchive, ZipArchiveEntry, DeflateStream, and GZipStream classes.

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. To use the ZipFile class, you must reference the System.IO.Compression.FileSystem assembly in your project.

using System;
using System.IO;
using System.IO.Compression;

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

            ZipFile.CreateFromDirectory(startPath, zipPath);

            ZipFile.ExtractToDirectory(zipPath, extractPath);
        }
    }
}
