带有嵌入式开关的powershell foreach-object不锻炼

Question

试图从文本电子邮件中总计购买的时间。这是我拥有的代码，我希望它足够近，可以解释我要做什么。对我来说很有意义，但不豪华。

$n = select-string -Path "$global:EMLpath\*.eml" -Pattern "[ORDER #" -SimpleMatch -CaseSensitive -Context 0,10
$n.Context.PostContext|
          ForEach-Object{
            Switch -Wildcard ($Inputstring = $_) {
                $Inputstring -like "Hourly*" {$ADDhrs = 1 * (-split "$Inputstring")[4]}
                $Inputstring -like "Weekly*" {$ADDhrs = 168 * (-split "$Inputstring")[4]}
                $Inputstring -like "Monthly*" {$ADDhrs = 720 * (-split "$Inputstring")[4]}
                $Inputstring -like "Yearly*" {$ADDhrs = 8640 * (-split "$Inputstring")[4]}
             }
 }

文件中的相关文本是：

=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
New Order: #1667
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

You’ve received the following order from Joe Shmo:

[ORDER #1667] (2022-04-28)

Monthly Server Rental X 1 = $26.56
Weekly Server Rental X 2 = $26.56

感谢圣地亚哥，这现在有效。

$n = select-string -Path "$global:EMLpath\*.eml" -Pattern "[ORDER #" -SimpleMatch -CaseSensitive -Context 0,10
$ADDhrs = 0
$n.Context.PostContext|
          ForEach-Object{
            Switch -Wildcard ($Inputstring = $_) {
                "Hourly*" {$ADDhrs = $ADDhrs + (1 * (-split "$Inputstring")[4])}
                "Weekly*" {$ADDhrs = $ADDhrs + (168 * (-split "$Inputstring")[4])}
                "Monthly*" {$ADDhrs = $ADDhrs + (720 * (-split "$Inputstring")[4])}
                "Yearly*" {$ADDhrs = $ADDhrs + (8640 * (-split "$Inputstring")[4])}
             }
 }
