我想将productName（product2）的值更改为（product fornonox 2）

我尝试了以下代码，但没有用：

$products_fortnox = import-csv -Path .\products_Fortnox_output.csv 
$products_fortnox | % {

if ($_.productNumber -eq "1A100110002") {

$_.productName = 'product fortnox 2'
} 
}

$products_fortnox | export-csv .\products_Fortnox_output.csv -NoTypeInformation

Answer 1

尝试这个：

$source  = '.\products_Fortnox_output.csv '
$dest   = '.\products_Fortnox_output_new.csv '

[IO.File]::ReadAllText($filepath) -replace '(?m)^(1A100110002,)(prod.*)(,.*)$', '$1product fortnox 2$3' | Out-File $dest
