Powershell导出-CSV产生不希望的结果

Question

你好，我希望你们能帮我解决一个困扰我几天的问题。当我将脚本的结果导出到csv文件时，我无法得到正确的输出。

    [CmdletBinding()]

        [Parameter(
        Mandatory=$true,
        ValueFromPipeline=$true,
        ValueFromPipelineByPropertyName=$true)]

        [Parameter(Mandatory=$false)]

$obj | Export-Csv -Path "D:\Scripts\Test-Peter\Testing\lalala.csv" -NoTypeInformation

您创建了一个对象$obj来保存所有任务详细信息，而不是单个任务的集合：

$obj = New-Object –TypeName PSObject
$obj | Add-Member -MemberType NoteProperty -Name ServerName -Value $ComputerName
$obj | Add-Member -MemberType NoteProperty -Name TaskName -Value ([string]::Join(",",(@())))
# ... and so on

同样，不是将单个任务添加到数组/集合中，而是将每个属性的值添加到$obj的相同属性中：

$tskobj = New-Object -TypeName PSObject -Property $info 
$obj.TaskName += $tskobj.TaskName
$obj.ScheduledTaskState += $tskobj.ScheduledTaskState
$obj.LogonMode += $tskobj.LogonMode
$obj.Author += $tskobj.Author
$obj.RunAsUser += $tskobj.RunAsUser

您只需将$obj更改为空集合，并将任务分配给它：

$obj = @()

foreach($Task in (Get-ScheduledTask)){
    $TaskProperties = @{
        'TaskName'=$Task.TaskName;
        'ScheduledTaskState'=$Task.ScheduledTaskState;
        'LogonMode'=$Task.LogonMode;
        'Author'=$Task.Author;
        'RunAsUser'=$Task.RunAsUser
    }
    $obj += New-Object psobject -Property $TaskProperties
}

$obj | Export-Csv "output.csv"
