我有一個帶有自定義物件的 Arraylist，想找到“Jobname”相同的所有物件。Group-Object 不能按我想要的方式作業，因為它只計算所有屬性 (10)。我什至開始認為我錯誤地使用了 Arraylist。代碼中物件的創建僅用于測驗，實際上我正在使用回圈來填充我的陣列。

uj5u.com熱心網友回復：
使用Script-scoping而不是 Global 應該綽綽有余。
然后$script:BackupJobObjectArray只在函式內部使用，因為無論如何都知道串列之外。
Add-Member您可以直接使用[PsCustomObject]并將其添加到串列中，而不是所有這些行。
最后，如果我正確理解你的問題，你會想根據 JobName 獲得一個表格格式的重復物件串列，你可以像下面那樣做
$BackupJobObjectArray = [System.Collections.Generic.List[object]]::new()
function AddBackupJobFoldertoArray {
param(
[string]$jobservername,
[string]$backupjobfolder,
[string]$backupjobname,
[string]$jobmandant,
[int64]$size,
[int64]$sizeGB,
[int64]$sizeTB,
[string]$BackupServer,
[int]$vbkcount,
[string]$lastmodifiedfile
)
$script:BackupJobObjectArray.Add([PsCustomObject]@{
Jobname = $backupjobname
Mandant = $jobmandant
Servername = $jobservername
Filepath = $backupjobfolder
Size = $size
SizeGB = $sizeGB
SizeTB = $sizeTB
Backupserver = $BackupServer
VBKCount = $vbkcount
LastModified = $lastmodifiedfile
})
}

我個人會選擇 List 物件，但 ArrayList 也可以。
