将自定义PowerShell对象导出为CSV

Question

我想创建一个完整的邮箱权限报告，并将其导出到PowerShell中的CSV中。

$report = @()
$mailboxes = Get-Mailbox -ResultSize unlimited -RecipientTypeDetails sharedmailbox

foreach ($mailbox in $mailboxes)
{ 
    $permissions = Get-Mailbox $mailbox.PrimarySmtpAddress | Get-MailboxPermission | Select-Object user, accessrights
    $users = $permissions.user
    $accessRights = $permissions.accessrights
    $sendAsPermissions = Get-Mailbox $mailbox.PrimarySmtpAddress | Get-ADPermission | Where-Object {$_.extendedrights -eq "send-as"} | select -ExpandProperty user
    $sendOnBehalfPermissions = Get-Mailbox $mailbox.PrimarySmtpAddress | select -ExpandProperty grantsendonbehalfto

    $properties = @{
    Identity = $mailbox.PrimarySmtpAddress
    Users = ($permissions.user -join "`n")
    AccessRights = ($permissions.accessrights -join "`n")
    SendAs = ($sendAsPermissions -join "`n")  
    SendOnBehalf = ($sendOnBehalfPermissions -join "`n")
    }

    $mailboxObject = New-Object -TypeName psobject -Property $properties

    #$mailboxObject | select identity, users, accessrights | Export-Csv -Append -NoTypeInformation -Path c:\temp\test.csv
    $mailboxObject | select identity, users, accessrights, sendas, sendonbehalf | out-gridview
}

gridview准确显示了我想要的内容，但是我很难将其正确导出到CSV。

我知道事实可能会更好，更适合您的实际情况，但认为仍然值得分享。

您可以获取Import-Excel模块，该模块可以轻松地创建和格式化Excel文件。 您可以从此处的Powershell Gallery安装它。 基本上，这是假设您的图纸仅适合人眼使用，并且考虑到格式，我想我可以肯定地说。

首先，我开始在追加之前收集所有对象，这是一个很常见的错误。 只需直接输出对象并将其收集在变量中即可。

$report = @()
$mailboxes = Get-Mailbox -ResultSize unlimited -RecipientTypeDetails sharedmailbox

$collectOutput = foreach ($mailbox in $mailboxes)
{ 
  $permissions = Get-Mailbox $mailbox.PrimarySmtpAddress | Get-MailboxPermission | Select-Object user, accessrights
  $users = $permissions.user
  $accessRights = $permissions.accessrights
  $sendAsPermissions = Get-Mailbox $mailbox.PrimarySmtpAddress | Get-ADPermission | 
    Where-Object {
      $_.extendedrights -eq 'send-as'
    } | Select-Object -ExpandProperty user
  $sendOnBehalfPermissions = Get-Mailbox $mailbox.PrimarySmtpAddress | Select-Object -ExpandProperty grantsendonbehalfto

  [pscustomobject]@{
    Identity     = $mailbox.PrimarySmtpAddress
    Users        = ($permissions.user -join "`r`n")
    AccessRights = ($permissions.accessrights -join "`r`n")
    SendAs       = ($sendAsPermissions -join "`r`n")
    SendOnBehalf = ($sendOnBehalfPermissions -join "`r`n")
  }
}

现在，我将使用Export-Excel cmdlet生成OfficeOpenXml.ExcelPackage对象，然后我们可以使用一些辅助函数对其进行操作。 我发现这几乎模拟了Out-Gridview 。 标头换行只有一点点，但是欢迎您尝试不同的参数，直到找到看起来完全合适的东西。

$sheet = $collectOutput | Export-Excel -Path 'C:\Users\username\Desktop\testing.xlsx' -PassThru -AutoSize

$sheet.Sheet1.Column(1) | Set-ExcelRange -VerticalAlignment Center
$sheet.Sheet1.Column(2) | Set-ExcelRange -WrapText
$sheet.Sheet1.Column(3) | Set-ExcelRange -WrapText
$sheet.Sheet1.Column(4) | Set-ExcelRange -WrapText

$sheet.Save()
$sheet.Dispose()

Answer 2

Export-Csv为此。

这是一个工作示例：

$o = [PSCustomObject]@{a = 1 } ,
     [PSCustomObject]@{a = 2 }

# Export     
$o | Export-Csv -Path a.csv

# check the file
Get-Content ./a.csv

要查找使用csv的命令，可以使用

Get-Command *csv*

Answer 3

要转换对象，可以在选择结果上使用管道将其转换为ConvertTo-Csv，如下所示：

  $selectResult = $mailboxObject | select identity, users, accessrights, sendas, sendonbehalf
  $selectResult | out-gridview
  $selectResult | ConvertTo-Csv > .\mailbox.csv

Answer 4

你可以试试这个吗

Identity = $mailbox.PrimarySmtpAddress
Users = (@($permissions.user -join "`n") |Out-String).Trim()
AccessRights = (@($permissions.accessrights -join "`n")|Out-String).Trim()
SendAs = (@($sendAsPermissions -join "`n") |Out-String).Trim() 
SendOnBehalf =(@($sendOnBehalfPermissions -join "`n")|Out-String).Trim()
