在 Powershell 中，將 PSCustomObjects 數組保存並恢復到文件中，以供以后重新加載和重新使用

Question

有沒有辦法將 Get-ChildItem 的輸出寫入文件並保留 [PSCustomObjects] 數組，然后再讀取此文件並將其轉換回 [PSCustomObjects] 數組？

$gci = get-childitem -recurse

# How to implement this
save_file -file "list.gci". -value $gci

# How to implement this 
$gci2 = load_file -file "list.gci" 

foreach ($item in $gci2) {
    $fullname = $gci2.fullname
    $CreatationDate = $gci2.CreationDate
    write-host "$fullname"
}

擴展 Olaf 的評論，Powershell 可以使用CLIXML將具有類型信息和屬性的復雜對象保存到文件中：

# export to file
$gci = Get-ChildItem -Recurse
$gci | Export-Clixml c:\path\to\file.xml

# import later:
$gci2 = Import-Clixml c:\path\to\file.xml

# objects are still FileInfo objects:
$gci2 | Get-Member

   TypeName: Deserialized.System.IO.FileInfo
