Question

我有一个 .csv 文件，我将其分组为两个属性 'DN'、'SKU'，然后对另一个属性 'DeliQty' 执行求和这工作正常，总和反映回组。但是，然后我需要在 'DN' 上重新分组并写出到单独的文件中。我试过 Select-Object -Expand Group 但这会恢复到原始内容而没有求和行。

有没有办法取消分组保留求和行然后再次分组？

$CSVFiles = Get-ChildItem -Path C:\Scripts\INVENTORY\ASN\IMPORT\ -Filter *.csv

foreach ($csv in $CSVFiles) {
    $group = Import-Csv $csv.FullName | Group-Object DN, SKU
    $group | Where Count -gt 1 | ForEach-Object {
    $_.Group[0].'DeliQty' = ($_.Group | Measure-Object DeliQty -Sum).Sum 
    } 
    }

您可以执行以下操作：

$CSVFiles = Get-ChildItem -Path C:\Scripts\INVENTORY\ASN\IMPORT\ -Filter *.csv

foreach ($csv in $CSVFiles) {
    $group = Import-Csv $csv.FullName | Group-Object DN, SKU | Foreach-Object {
        if ($_.Count -gt 1) {
            $_.Group[0].DeliQty = ($_.Group | Measure-Object DeliQty -Sum).Sum
        }
        $_.Group[0]
    } 
    # outputs summed and single group objects
    $group
}
