arrays - 在循环中填充对象并将整个数组输出到CSV

Question

我目前有一个脚本，该脚本将通过文件夹运行并打开其中的每个PDF，然后将弹出一个输入框，询问我要将文件重命名为什么。这部分工作正常，但是我试图用每个文件的信息填充数组，例如创建日期，修改日期，旧文件名和新文件名。

我目前拥有的代码是:

Add-Type -AssemblyName Microsoft.VisualBasic 

$folderpath = 'file path'
$items = Get-ChildItem -Recurse $folderpath *.pdf
$newFileName = "" 
$counterID = 0
$amountOfScans = $items.Length
$typeOfScanner = ""

$scanArray = @()
$scanObject = New-Object System.Object

foreach( $i in $items)  {
    Start-Process ((Resolve-Path ("$folderpath$i")).Path)
    Start-Sleep -Seconds 1
    $counterID++ 

    $orderID = [Microsoft.VisualBasic.Interaction]::InputBox("Enter the new file name for scan $counterID / $amountOfScans :", $i)

    if ($newFileName -eq "delete"){
        $reasonForDeletion = [Microsoft.VisualBasic.Interaction]::InputBox("Enter a reason for marking $i for deletion :", $i)
    }

    if ($i.Length -eq 24){
        $typeOfScanner = "Xerox"
    }
    elseif ($ie.Length -eq 33) {
        $typeOfScanner = "Lexmark"
    }

    $DateCreated = Get-ItemProperty ((Resolve-Path ("$folderpath$i")).Path) | select -exp CreationTime
    $DateModified1 = Get-Date -Format dd/MM/yyyy        
    $DateModified2 = Get-Date -Format HH:mm:ss
    $DateModifiedTotal = ("$DateModified1 $DateModified2")

    $scanObject[$counterID] | Add-Member -type NoteProperty -name TempName -Value "$i" 
    $scanObject[$counterID] | Add-Member -type NoteProperty -name NewName -Value "$orderID"
    $scanObject[$counterID] | Add-Member -type NoteProperty -name TypeOfScanner -Value "$typeOfScanner"
    $scanObject[$counterID] | Add-Member -type NoteProperty -name DateCreated -Value "$DateCreated"
    $scanObject[$counterID] | Add-Member -type NoteProperty -name DateModified -Value "$DateModifiedTotal"
    $scanObject[$counterID] | Add-Member -type NoteProperty -name ReasonForDeletion -Value "$reasonForDeletion"

    $scanArray += $scanObject[$counterID]

    Stop-Process -Name "Acro*"
}

$scanArray | export-csv C:\Scans\renamed_stats.csv -notypeinformation

但是，运行此脚本后，“renamed_stats.csv”完全空白，没有错误消息。

任何帮助，将不胜感激 :)

假设您没有太多的对象来耗尽内存，并且像$i这样的值变量包含了预期值，则可以完全摆脱$scanObject并执行以下操作:

[array]$scanArray += [PSCustomObject] @{
    TempName          = "$i"
    NewName           = "$orderID"
    TypeOfScanner     = "$typeOfScanner"
    DateCreated       = "$DateCreated"
    DateModified      = "$DateModifiedTotal"
    ReasonForDeletion = "$reasonForDeletion"
}

您还可以通过使用引号来改善日期部分:

$DateModified = Get-Date -Format "dd/MM/yyyy HH:mm:ss"
