Powershell 包括if/else逻辑

您好，我正在尝试

if/else

并编写两个单独的文件，

如果存在
PST
，请执行以下操作<代码>导出Csv-非类型信息C:\$UserName-$ComputerName OpenPSTs-$Date.Csv

Else

导出Csv-notype信息C:\$UserName-$ComputerName NOPSTs-$Date.Csv

谁能推荐一下吗

$Date = Get-Date -format d-M-yyyy
$UserName = $env:USERNAME
$ComputerName = $env:COMPUTERNAME
$Outlook = New-Object -comObject Outlook.Application

$object = $Outlook.Session.Stores | Where {$_.FilePath -like "*.PST"} | Select `
@{Expression={$_.DisplayName}; Label="PST Name in Outlook"},`
@{Expression={$_.FilePath}; Label="PST Location/FileName"},`
@{Expression={$_.IsOpen}; Label="PST Open in Outlook"},`
@{Expression={(Get-Item $_.FilePath).Length / 1KB}; Label="PST File Size (KB)"}
$object | Add-Member -MemberType NoteProperty -Name 'ComputerName' -Value $ComputerName
$object | Add-Member -MemberType NoteProperty -Name 'UserName' -Value $UserName
$object | Export-Csv -NoTypeInformation C:\$UserName-$ComputerName-OpenPSTs-$Date.csv

Start-Sleep 5
Get-Process | Where {$_.Name -like "Outlook*"} | Stop-Process

---

您可以将

Where Object

过滤器替换为

ForEach Object

循环和嵌套条件：

$Outlook.Session.Stores | % {
  if ($_.FilePath -like '*.pst') {
    $_ | select ... | Export-Csv 'OpenPST.csv' -NoType -Append
  } else {
    $_ | select ... | Export-Csv 'NoPST.csv' -NoType -Append
  }
}

但是，这可能执行得不太好，因为它会重复地附加到输出文件中。最好只运行两条带有互补过滤器的管道：

$stores = $Outlook.Session.Stores

$stores | ? { $_.FilePath -like '*.pst' } | select ... |
    Export-Csv 'OpenPST.csv' -NoType
$stores | ? { $_.FilePath -notlike '*.pst' } | select ... |
    Export-Csv 'NoPST.csv' -NoType
