If Else 语句 Powershell CSV

Question

当我运行我的代码时，它给了我以下错误。 我让代码做的是获取 csv 然后将名称列过滤为仅是管理员，然后我让标题列过滤我提供的所有操作系统。 if 语句是说如果列 Type0 等于域，则将 Domain0 放在 Account0 后面的“唯一帐户名称”列中。否则，它将把它放在 Netbios 名称中，然后是 Account0。下面是excel表格。以及每个所需的输出。

 Import-Csv 'U:\Local Group Members.csv' | where-Object {($_.Name0 -eq "administrators") -and ($_.caption0 -match "Microsoft Windows 10 Enterprise|Microsoft Windows 7 Enterprise|Microsoft Windows 7 Professional|Microsoft Windows 8 Enterprise|Microsoft Windows 8 Pro|Microsoft Windows 8.1 Enterprise|Microsoft Windows 8.1 Pro")} |
Select-Object "Netbios_name0", "Name0", "Account0","category0","Domain0","Unique Account Name","Type0","caption0", "Excluded" |
ForEach-Object 

If ($_.Type0 -eq 'Domain') { 
    $_.UniqueAccountName = "$($_.Domain0) - $($_.Account0)" 
} Else { 
    $_.UniqueAccountName = "$($_.Netbios_name0) - $($_.Account0)" 
}

Export-Csv -notypeinformation U:\LGMbestone.csv

我是powershell新手，卡住了，如何让这段代码运行？

您不能通过管道传递到 if 语句，并且您需要逐行遍历结果以修改对象，这需要一个 foreach 循环。此外，通过管道传输到 Export-CSV 比使用输入对象调用它要好。下面是基于您的代码的示例。希望这会有所帮助！

    $csv = Import-Csv 'U:\Local Group Members.csv' |
Where-Object {($_.Name0 -eq "administrators") -and ($_.caption0 -match "Microsoft Windows 10 Enterprise|Microsoft Windows 7 Enterprise|Microsoft Windows 7 Professional|Microsoft Windows 8 Enterprise|Microsoft Windows 8 Pro|Microsoft Windows 8.1 Enterprise|Microsoft Windows 8.1 Pro")} |
Select-Object "Netbios_name0", "Name0", "Account0","category0","Domain0","Unique Account Name","Type0","caption0", "Excluded"

#Modify each line based on your parameters
Foreach ($row in $csv) {
    If ($row.Type0 -eq 'Domain') { 
        $row."Unique Account Name" = "$($row.Domain0) - $($row.Account0)" 
        Write-Host $row."Unique Account Name"
    } Else { 
        $row."Unique Account Name" = "$($row.Netbios_name0) - $($row.Account0)"
    }
}

#Export CSV
$csv | Export-Csv C:\LGMbestone.csv -NoTypeInformation

看起来像是一个格式问题。对于 foreach ，它应该是这样的：

$import=Import-Csv 'U:\Local Group Members.csv' | where-Object {($_.Name0 -eq "administrators") -and ($_.caption0 -match "Microsoft Windows 10 Enterprise|Microsoft Windows 7 Enterprise|Microsoft Windows 7 Professional|Microsoft Windows 8 Enterprise|Microsoft Windows 8 Pro|Microsoft Windows 8.1 Enterprise|Microsoft Windows 8.1 Pro")} |
Select-Object "Netbios_name0", "Name0", "Account0","category0","Domain0","Unique Account Name","Type0","caption0", "Excluded" 

ForEach($imp in $import)
{ 

    If ($imp.Type0 -eq 'Domain') 
    { 
        $imp.UniqueAccountName = "$($imp.Domain0) - $($imp.Account0)" 
    } 
    Else 
    { 
        $imp.UniqueAccountName = "$($imp.Netbios_name0) - $($imp.Account0)" 
    }

    Export-Csv "$imp.UniqueAccountName" -notypeinformation "U:\LGMbestone.csv" -Append
}

注意：我没有检查 import-csv 部分。我相信它正确地获取数据，你应该使用 foreach 循环来迭代每一行值
