static member ExtractToDirectory : string * string * System.IO.Compression.ZipExtractionOptions -> unit

Public Shared Sub ExtractToDirectory (sourceArchiveFileName As String, destinationDirectoryName As String, options As ZipExtractionOptions)

Parameters

sourceArchiveFileName: String

destinationDirectoryName: String

The path to the directory in which to place the extracted files. The directory can already exist. Missing directories are created as needed when extracting entries.

options: ZipExtractionOptions

Remarks

Warning

This method must not be used to extract untrusted archives. It doesn't enforce any size limits, entry count limits, or other policies needed for safe extraction of untrusted archives. For more information on safely extracting archives from untrusted sources, see Best practices for using zip and tar archives.

The directory specified by destinationDirectoryName can already exist. This method creates the destination directory, its missing parent directories, and subdirectories as needed when extracting entries. If the archive is empty, this method doesn't create the destination directory.

Each extracted file has the same relative path to destinationDirectoryName as its source entry has to the root of the archive.

The sourceArchiveFileName and destinationDirectoryName parameters accept relative and absolute paths. A relative path is interpreted as relative to the current working directory.

If an error occurs during extraction, the archive remains partially extracted.

Set OverwriteFiles to true to overwrite existing files. The default is false, which causes extraction to throw an IOException if a file to be extracted already exists.

Use Password to supply the password for encrypted entries.

Use EntryNameEncoding to specify the encoding for entry names and comments when opening the archive. For details about how this encoding is used, see ZipArchive(Stream, ZipArchiveMode, Boolean, Encoding).

Symbolic links in the archive aren't recreated as symbolic links. If destinationDirectoryName or any of its parent directories is a pre-existing junction or symbolic link, the link is followed and extraction writes to the final target folder.

static member ExtractToDirectory : string * string * System.Text.Encoding * bool -> unit

Public Shared Sub ExtractToDirectory (sourceArchiveFileName As String, destinationDirectoryName As String, entryNameEncoding As Encoding, overwriteFiles As Boolean)

Parameters

sourceArchiveFileName: String

The path on the file system to the archive that is to be extracted.

destinationDirectoryName: String

The path to the destination directory on the file system. The directory can already exist. Missing directories are created as needed when extracting entries.

entryNameEncoding: Encoding

The encoding to use when reading entry names and comments in this ZipArchive.

overwriteFiles: Boolean

true to overwrite files; false otherwise.

Exceptions

ArgumentException

sourceArchiveFileName or destinationDirectoryName is a zero-length string, contains only whitespace, or contains one or more invalid characters as defined by InvalidPathChars.

-or-

entryNameEncoding is set to a Unicode encoding other than UTF-8.

ArgumentNullException

sourceArchiveFileName or destinationDirectoryName is null.

PathTooLongException

sourceArchiveFileName or destinationDirectoryName specifies a path, a file name, or both that exceed the system-defined maximum length.

DirectoryNotFoundException

The path specified by sourceArchiveFileName or destinationDirectoryName is invalid (for example, it is on an unmapped drive).

IOException

overwriteFiles is false and an archive entry to extract has the same name as a file that already exists in destinationDirectoryName.

-or-

An I/O error has occurred.

-or-

The name of a ZipArchiveEntry is zero-length, contains only whitespace, or contains one or more invalid characters as defined by InvalidPathChars.

-or-

Extracting a ZipArchiveEntry would result in a file destination that is outside the destination directory (for example, because of parent directory accessors).

-or-

A ZipArchiveEntry has the same name as an already extracted entry from the same archive.

UnauthorizedAccessException

The caller does not have the required permission.

NotSupportedException

sourceArchiveFileName or destinationDirectoryName is in an invalid format.

FileNotFoundException

sourceArchiveFileName was not found.

InvalidDataException

The archive specified by sourceArchiveFileName is not a valid ZipArchive.

-or-

An archive entry was not found or was corrupt.

-or-

An archive entry has been compressed using a compression method that isn't supported.

Remarks

Warning

If there is an error while extracting the archive, the archive will remain partially extracted.

Each entry will be extracted such that the extracted file has the same relative path to the destinationDirectoryName as the entry has to the archive.

The sourceArchiveFileName and destinationDirectoryName parameters accept both relative and absolute paths. A relative path is interpreted as relative to the current working directory.

If an entry in the zip archive is a symbolic link, it's extracted as a regular folder since symbolic link information isn't preserved in the ZIP format. If destinationDirectoryName or any of its parent directories is a pre-existing junction or symbolic link, the link is followed and the extraction writes to the final target folder.

If a file to be archived has an invalid last modified time, the first date and time representable in the zip timestamp format (midnight on January 1, 1980) will be used.

Parameters

source: Stream

The stream from which the zip archive is to be extracted.

destinationDirectoryName: String

The path to the directory in which to place the extracted files, specified as a relative or absolute path. A relative path is interpreted as relative to the current working directory. The directory can already exist. Missing directories are created as needed when extracting entries.

entryNameEncoding: Encoding

The encoding to use when reading or writing entry names and comments in this archive. Specify a value for this parameter only when an encoding is required for interoperability with zip archive tools and libraries that do not support UTF-8 encoding for entry names or comments.

IOException

The name of an entry in the archive is Empty, contains only white space, or contains at least one invalid character.

-or-

Extracting an archive entry would create a file that is outside the directory specified by destinationDirectoryName. (For example, this might happen if the entry name contains parent directory accessors.)

-or-

overwriteFiles is false and an archive entry to extract has the same name as an entry that has already been extracted or that exists in destinationDirectoryName.

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 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.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);
    }
}

open System.IO.Compression

let startPath = @".\start"
let zipPath = @".\result.zip"
let extractPath = @".\extract"

ZipFile.CreateFromDirectory(startPath, zipPath)

ZipFile.ExtractToDirectory(zipPath, extractPath)

Imports System.IO.Compression

Module Module1

    Sub Main()
        Dim startPath As String = ".\start"
