Powershell 首先将标题写入csv，然后附加相应的列数据

我正在尝试用下面的数据创建一个csv。但我不知道这是怎么回事

新提取的\u数据是一个数组：

timestamp  _ldmodels_MIN _ldmodels_MAX _ldmodels_AVERAGE
---------  ------------- ------------- -----------------
1599136260 73896.68      73896.68      73896.68         
1599136320 73896.68      73896.68      73896.68         
1599136380 73896.68      73896.68      73896.68         

下面是我计划编写头的方式，头是noteproperty，而不是数组中的头

然后我计算每个成员类型的列的总和

                       foreach($Member in $GetMembers)
                            {
                                $Col = $Member.Name
                                if($Col -ne "timestamp")
                                {                                
                                   $Sum_Col = ($New_Extracted_Data | Measure-Object $Col -Sum).Sum                                
                                }
                             }

现在我需要将其写入csv。以下是预期的o/p e、 g

请需要关于如何做到这一点的想法。另外，如果我的方法有任何问题，请告诉我。

除非只是需要一个理论解释，否则在给定的示例中，您的需求没有实际应用<代码>导出Csv可以将PowerShell对象序列化为Csv格式<代码>选择对象可用于筛选发送到

导出Csv

的属性

# Export Your Object to CSV with all custom properties as columns
$New_Extracted_Data | Export-Csv "C:\Script\Final_Data.csv" -NoType

# Export object to CSV without timestamp property
$New_Extracted_Data | Select-Object -Property * -ExcludeProperty timestamp |
    Export-Csv "C:\Script\Final_Data.csv" -NoType

# Creating sums of your values when properties are known
[pscustomobject]@{
    _ldmodels_MIN = ($New_Extracted_Data._ldmodels_MIN | Measure -Sum).Sum
    _ldmodels_MAX = ($New_Extracted_Data._ldmodels_MAX | Measure -Sum).Sum
    _ldmodels_AVERAGE = ($New_Extracted_Data._ldmodels_AVERAGE | Measure -Sum).Sum
} | Export-Csv sums.csv -NoType

# Summing all properties except timestamp
$Properties = ($New_Extracted_Data[0] | Get-Member -MemberType NoteProperty |
    Where Name -ne 'timestamp').Name
$Hash = [ordered]@{}
foreach ($Property in $Properties) {
    $Hash[$Property] = ($New_Extracted_Data.$Property | Measure -Sum).Sum
}
[pscustomobject]$Hash | Export-Csv sum.csv -NoType

没有必要循环。只需使用

-join

-->

$GetMembers.Name-join'，

。为什么要这样做？为什么不只是

$New_Extracted_Data | Export Csv

？

_ldmodels_MIN _ldmodels_MAX _ldmodels_AVERAGE
