如果你安装了WinRAR:

function ZipUsingRar([String] $directory, [String] $zipFileName)
{
  Write-Output "Performing operation ""Zip File"" on Target ""Item: $directory Destination:"
  Write-Output ($zipFileName + """")
  $pathToWinRar = "c:\Program Files\WinRAR\WinRar.exe";
  [Array]$arguments = "a", "-afzip", "-df", "-ep1", "$zipFileName", "$directory";
  & $pathToWinRar $arguments;
}

参数的含义:afzip创建zip归档，df删除文件，ep1不创建归档内的完整目录路径

这里有一个完整的命令行示例，可以从cmd.exe或ssh或您想要的任何地方启动!

powershell.exe -nologo -noprofile -command "&{ Add-Type -A 'System.IO.Compression.FileSystem' [System.IO.Compression.ZipFile]::CreateFromDirectory('c:/path/to/source/folder/', 'c:/path/to/output/file.zip');}"

问候

这也可以在不使用临时文件夹的情况下压缩单个文件，并使用原生的。net 4.5，从c#转换到这个StackOverflow答案。它使用了更好的使用语法。

用法:

zipfile - zipfilen输出.zip -sourceFile输入。sql -file, inside.zip.sql

代码:

function ZipFiles([string] $zipFilename, [string] $sourceFile, [string] $filename)
{
    $fullSourceFile = (Get-Item -Path "$sourceFile" -Verbose).FullName
    $fullZipFile = (Get-Item -Path "$zipFilename" -Verbose).FullName

    Add-Type -AssemblyName System.IO
    Add-Type -AssemblyName System.IO.Compression
    Add-Type -AssemblyName System.IO.Compression.FileSystem

    Using-Object ($fs = New-Object System.IO.FileStream($fullZipFile, [System.IO.FileMode]::Create)) {
         Using-Object ($arch = New-Object System.IO.Compression.ZipArchive($fs, [System.IO.Compression.ZipArchiveMode]::Create)) {
             [System.IO.Compression.ZipFileExtensions]::CreateEntryFromFile($arch, $fullSourceFile, $filename)
        }
    }
}

使用:

function Using-Object
{
    [CmdletBinding()]
    param (
        [Parameter(Mandatory = $true)]
        [AllowEmptyString()]
        [AllowEmptyCollection()]
        [AllowNull()]
        [Object]
        $InputObject,

        [Parameter(Mandatory = $true)]
        [scriptblock]
        $ScriptBlock
    )

    try
    {
        . $ScriptBlock
    }
    finally
    {
        if ($null -ne $InputObject -and $InputObject -is [System.IDisposable])
        {
            $InputObject.Dispose()
        }
    }
}

旧线程，但仍然，我到了这里:)

这不是最初问题的答案，但也许有人会发现如何用PS创建ZipArchive对象是有用的。

# Example, if you have like I have a $myByteArray byte[] with the compressed data:
Add-Type -AssemblyName System.IO.Compression.FileSystem

# Fixed length stream:
$strm = New-Object -TypeName System.IO.MemoryStream -ArgumentList @(, $myByteArray);

# Create ZipArchive object
$arch = [System.IO.Compression.ZipArchive]::new($strm);

# List entries
$arch.Entries

如果有人需要压缩单个文件(而不是一个文件夹):http://blogs.msdn.com/b/jerrydixon/archive/2014/08/08/zipping-a-single-file-with-powershell.aspx

[CmdletBinding()]
Param(
     [Parameter(Mandatory=$True)]
     [ValidateScript({Test-Path -Path $_ -PathType Leaf})]
     [string]$sourceFile,

     [Parameter(Mandatory=$True)]
     [ValidateScript({-not(Test-Path -Path $_ -PathType Leaf)})]
     [string]$destinationFile
) 

<#
     .SYNOPSIS
     Creates a ZIP file that contains the specified innput file.

     .EXAMPLE
     FileZipper -sourceFile c:\test\inputfile.txt 
                -destinationFile c:\test\outputFile.zip
#> 

function New-Zip
{
     param([string]$zipfilename)
     set-content $zipfilename 
          ("PK" + [char]5 + [char]6 + ("$([char]0)" * 18))
     (dir $zipfilename).IsReadOnly = $false
}

function Add-Zip
{
     param([string]$zipfilename) 

     if(-not (test-path($zipfilename)))
     {
          set-content $zipfilename 
               ("PK" + [char]5 + [char]6 + ("$([char]0)" * 18))
          (dir $zipfilename).IsReadOnly = $false    

     }

     $shellApplication = new-object -com shell.application
     $zipPackage = $shellApplication.NameSpace($zipfilename)


     foreach($file in $input) 
     { 
          $zipPackage.CopyHere($file.FullName)
          Start-sleep -milliseconds 500
     }
}

dir $sourceFile | Add-Zip $destinationFile

下面是工作代码，压缩源文件夹中的所有文件，并在目标文件夹中创建一个zip文件。

    $DestZip="C:\Destination\"
    $Source = "C:\Source\"

    $folder = Get-Item -Path $Source

    $ZipTimestamp = Get-Date -format yyyyMMdd-HHmmss;
    $ZipFileName  = $DestZip + "Backup_" + $folder.name + "_" + $ZipTimestamp + ".zip" 

    $Source

    set-content $ZipFileName ("PK" + [char]5 + [char]6 + ("$([char]0)" * 18)) 
    # Wait for the zip file to be created.
    while (!(Test-Path -PathType leaf -Path $ZipFileName))
    {    
        Start-Sleep -Milliseconds 20
    } 
    $ZipFile = (new-object -com shell.application).NameSpace($ZipFileName)

    Write-Output (">> Waiting Compression : " + $ZipFileName)       

    #BACKUP - COPY
    $ZipFile.CopyHere($Source) 

    $ZipFileName
    # ARCHIVE

    Read-Host "Please Enter.."
