我想拉开拉链

Get-ChildItem -Path E:\test | Where-Object {$_.PSIsContainer} | Sort-Object LastWriteTime -Descending | Select-Object -First 1

我试过这个

$command ='Get-ChildItem -Path E:\test | Where-Object {$_.PSIsContainer} | Sort-Object LastWriteTime -Descending | Select-Object -First 1';

$file= iex $command

并将 $file 放入 zip 函数中但导致错误。

您的代码中缺少某些内容。就目前而言，这不包含有关压缩目录的信息。您显示的代码问题的根源是您要求Invoke-Expression运行文件夹名称。您的 $command 正在返回一个包含一个文件夹的对象。那是你想要的吗？

然后，您将该文件夹对象放入Invoke-Expression. $file =表示您的意思是将结果Invoke-Expression放入$file. 我还注意到你有单引号中的命令，这意味着Invoke-Expression会尝试扩展它。需要进行更多测试。我猜你想稍微改变一下。

$folder = Get-ChildItem -Path E:\test | Where-Object {$_.PSIsContainer} | Sort-Object LastWriteTime -Descending | Select-Object -First 1 -ExpandProperty FullName

这至少会返回您正在寻找的完整文件夹路径。你试图用它做的是我迷失的东西。如果你至少有 DotNet 4.5，你可以像这个例子一样从另一个SO 问题中压缩

$folder = Get-ChildItem -Path E:\test | Where-Object {$_.PSIsContainer} | Sort-Object LastWriteTime -Descending | Select-Object -First 1 -ExpandProperty FullName
$destination = "e:\test\myZip.zip"
[Reflection.Assembly]::LoadWithPartialName( "System.IO.Compression.FileSystem" )
[System.IO.Compression.ZipFile]::CreateFromDirectory($folder, $destination)

借助PowerShell 社区扩展，您还可以找到一个名为 cmdlet Write-Zip，您也可以使用它

Get-ChildItem -Path E:\test | Where-Object {$_.PSIsContainer} | Sort-Object LastWriteTime -Descending | Select-Object -First 1 | Write-Zip -IncludeEmptyDirectories -OutputPath E:\Test\MyZip.zip

如果您愿意：这是一个仅使用 PowerShell 内置功能的解决方案使用 Powershell 或命令行在 Windows 中创建压缩/压缩文件夹
