Question

我从Active Directory获得了一个csv导出，如下所示：

Name,"GivenName","Surname","Department","LogonWorkstations"
jdoe,"John","Doe","Finance","pc1"
fbueller,"Ferris","Bueller","Sales","pc2"

现在我想在每个Workstation上搜索，检查文件夹是否存在并将该信息写回csv。

$input

正如您在代码中看到的，Add-Member将附加信息添加到{{1}}，但是在将其导出到csv后，该信息不可用。

Answer 1

有效。问题在于If条件。

$input = Import-Csv "C:\Scripts\input.csv"

ForEach ($line in $input) {
    Add-Member -InputObject $line -NotePropertyName "xyz" -NotePropertyValue "exists"
}

$input # here I get the information

$input | Export-Csv "C:\Scripts\output.csv" -NoTypeInformation -Encoding Unicode

我建议将Add-Member调用作为第一个命令移动到循环中，使用默认值（可能为空），然后在条件中设置值。

ForEach ($line in $input) 
{
    Add-Member -InputObject $line -NotePropertyName "xyz" -NotePropertyValue $null
    $wst = $line.LogonWorkstations

    If ($wst -ne "") 
    {

        If (Test-Connection $wst -Count 1 -Quiet -ErrorAction SilentlyContinue) 
        {
            If (Test-Path "\\$wst\c$\Program Files\xyz" -ErrorAction SilentlyContinue) 
            {
                $line.xyz = 'exists'
            }
        }
    }
}

Answer 2

您将新成员添加到变量$line并期望将其写回$input ..但不是。

试试这个：

$input = Import-Csv "C:\Scripts\input.csv"

$counter=0

ForEach ($line in $input) {
    $wst = $line.LogonWorkstations
    If ($wst -ne "") {
        If (-not ( Test-Connection $wst -Count 1 -Quiet -ErrorAction SilentlyContinue)) {
            If (-not (Test-Path "\\$wst\c$\Program Files\xyz" -ErrorAction SilentlyContinue)) {
                Add-Member -InputObject $input[$counter] -NotePropertyName "xyz" -NotePropertyValue "exists"
            }
        }
    }
    $counter++
}

$input # here I get the information

$input | Export-Csv "C:\Scripts\output.csv" -NoTypeInformation -Encoding Unicode

我更改了InputObject - 参数，将新成员写入input变量。

Answer 3

我建议使用calculated property进行此类修改：

Import-Csv "C:\Scripts\input.csv" |
    Select-Object *, @{n='xyz';e={
        $wst = $_.LogonWorkstations
        if ($wst) {
            if (Test-Connection $wst -Count 1 -Quiet -EA SilentlyContinue) {
                $path = "\\$wst\c$\Program Files\xyz"
                [bool](Test-Path $path -EA SilentlyContinue)
            }
        }
    }} |
    Export-Csv 'C:\Scripts\output.csv' -NoType -Encoding Unicode

使用Add-Member将内容添加到csv
