使用powershell格式化CSV文件输出

我编写了以下代码，将证书详细信息存储在csv文件中。它可以工作，但在csv文件的每一行中，开头的符号

@{

和结尾的符号

}

都会被写入。在包含标题的第一列中，符号

=

也会被写入。因此，我不知道如何在没有这些符号的情况下填充我的csv文件

这是我写的代码

$StartDate = Get-Date
 $CertPath = 'Cert:\LocalMachine\'

  $CertsDetail =  Get-ChildItem -Path $CertPath -Recurse | Where-Object {$_.PsIsContainer -ne $true } | ForEach-Object {                               
   $DaysLeft = (New-TimeSpan -Start $StartDate -End $_.NotAfter).Days
   If ($DaysLeft -lt 30) {
    $Under30 = $true
    $Text = "The Certificate is but valid about to expire"
}
Else {
    $Under30 = $false
}
If ($DaysLeft -lt 1) {
    $Expired = $true
    #$Not_Expired = $false
    $Text = "The Certificate is expired"
}
Else {
    $Expired = $false
    #$Not_Expired = $true
    $Text = "The Certificate is still valid and not going soon to expire"
}
[pscustomobject]@{Text=$Text;`
                Subject = $_.Subject;`
                ExpireDate = $_.NotAfter;`
                DaysRemaining = $DaysLeft;`
                Under30Days = $Under30;`
                Expired = $Expired;`
                #Not_Expired = $Not_Expired
                }

                }
         $obj = [PSCustomObject] @{
         'Example Header 1' = $null
         'Example Header 2' = $null
         'Example Header 3' = $null
         'Example Header 4' = $null 
         'Example Header 5' = $null 
         'Example Header 6' = $null 


$obj | Add-Content -Path 'C:\Users\hanna\Desktop\certificate.csv'
$CertsDetail | Add-Content -Path 'C:\Users\hanna\Desktop\certificate.csv'

---

试着这样做：

$StartDate = Get-Date
$CertPath = 'Cert:\LocalMachine\'
$CertsDetail = Get-ChildItem -Path $CertPath -Recurse | 
    Where-Object { $_.PsIsContainer -ne $true } | ForEach-Object {                               
    $DaysLeft = (New-TimeSpan -Start $StartDate -End $_.NotAfter).Days
    if ($DaysLeft -lt 1) {
        $Under30 = $true
        $Expired = $true
        $Text = "The Certificate is expired"
    }
    elseif ($DaysLeft -lt 30) {
        $Under30 = $true
        $Expired = $false
        $Text = "The Certificate is but valid about to expire"
    }
    else {
        $Under30 = $false
        $Expired = $false
        $Text = "The Certificate is still valid and not going soon to expire"
    }
    [PSCustomObject]@{
        Text = $Text
        Subject = $_.Subject
        ExpireDate = $_.NotAfter
        DaysRemaining = $DaysLeft
        Under30Days = $Under30
        Expired = $Expired
    }
}
$CertsDetail | Export-Csv -Path 'C:\Users\hanna\Desktop\certificate.csv'

$obj

的作用是什么？[1]删除整个

$obj

部分&以

$obj | Add Content

开头的行。[2] 将

$CertsDetail |

行更改为使用

导出CSV

而不是

添加内容

。[3] 阅读

获取帮助导出CSV

中的帮助。。。[咧嘴笑]它可以工作，但仍然有两件事：1->#键入System.Management.Automation.PSCustomObject出现在文件的头部2->以隐藏格式写入的过期日期（######）我还想知道如何使列的大小与内容相匹配，以摆脱

#TYPE System.Management.Automation.PSCustomObject

只需将

-NoTypeInformation

添加到

导出Csv

中，如下所示：

导出Csv-Path“C:\Users\hanna\Desktop\certificate.csv”-NoTypeInformation

如果调整列的大小（假设您在Excel中查看csv），是否允许您查看过期日期？
