如果您前往CodePlex并获取PowerShell社区扩展，您可以使用他们的write-zip cmdlet。

你可以去PowerShell画廊。

加载[System.IO.]类，并使用它的方法是抑制不必要错误的重要步骤，因为它不是PowerShell的原生类，所以如果没有它，将会出现各种错误上下文。

我错误地控制了我的脚本到T，但在使用[System.IO.Compression]时得到了很多额外的红色“文件存在”输出。ZipFile)类

function zipFiles(
    [Parameter(Position=0, Mandatory=$true]
    [string] $sourceFolder,
    [Parameter(Position=1, Mandatory=$true]
    [string]$zipFileName,
    [Parameter(Position=2, Mandatory=$false]
    [bool]$overwrite)

{   
Add-Type -Assembly System.IO
Add-Type -Assembly System.IO.Compression.FileSystem

$compressionLevel = [System.IO.Compression.CompressionLevel]::Optimal

$directoryTest = (Test-Path $dailyBackupDestFolder)
$fileTest = (Test-Path $zipFileName)

if ( $directoryTest -eq $false) 
{ 
    New-Item -ItemType Directory -Force -Path $dailyBackupDestFolder 
}

     if ( $fileTest -eq $true)
     {
           if ($overwrite -eq $true ){Remove-Item $zipFileName}
     }   


    try
    {
         [System.IO.Compression.ZipFile]::CreateFromDirectory($sourceFolder,$zipFileName,$compressionLevel)       

    }
    catch [System.IO.IOException] 
    {
       Write-Output ($dateTime + ' | ' + $_.Exception.Message ) | Out-File $logFile -append -force 
    }
} 

我在这里所做的是捕获这些IO错误，例如访问已经存在的文件，捕获该错误并将其指向我正在使用更大的程序维护的日志文件。

这很晦涩，但很有效。7za.exe是7zip的独立版本，可通过安装包获得。

# get files to be send
$logFiles = Get-ChildItem C:\Logging\*.* -Include *.log | where {$_.Name -match $yesterday} 

foreach ($logFile in $logFiles)
{
    Write-Host ("Processing " + $logFile.FullName)

    # compress file
    & ./7za.exe a -mmt=off ($logFile.FullName + ".7z") $logFile.FullName

}

System.IO.Packaging.ZipPackage呢?

它需要。net 3.0或更高版本。

#Load some assemblys. (No line break!)
[System.Reflection.Assembly]::Load("WindowsBase, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35")

#Create a zip file named "MyZipFile.zip". (No line break!)
$ZipPackage=[System.IO.Packaging.ZipPackage]::Open("C:\MyZipFile.zip",
   [System.IO.FileMode]"OpenOrCreate", [System.IO.FileAccess]"ReadWrite")

#The files I want to add to my archive:
$files = @("/Penguins.jpg", "/Lighthouse.jpg")

#For each file you want to add, we must extract the bytes
#and add them to a part of the zip file.
ForEach ($file In $files)
{
   $partName=New-Object System.Uri($file, [System.UriKind]"Relative")
   #Create each part. (No line break!)
   $part=$ZipPackage.CreatePart($partName, "",
      [System.IO.Packaging.CompressionOption]"Maximum")
   $bytes=[System.IO.File]::ReadAllBytes($file)
   $stream=$part.GetStream()
   $stream.Write($bytes, 0, $bytes.Length)
   $stream.Close()
}

#Close the package when we're done.
$ZipPackage.Close()

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.."

安装7zip(或下载命令行版本)并使用PowerShell方法:

function create-7zip([String] $aDirectory, [String] $aZipfile){
    [string]$pathToZipExe = "$($Env:ProgramFiles)\7-Zip\7z.exe";
    [Array]$arguments = "a", "-tzip", "$aZipfile", "$aDirectory", "-r";
    & $pathToZipExe $arguments;
}

你可以这样调用它:

create-7zip "c:\temp\myFolder" "c:\temp\myFolder.zip"
