Powershell

如何從 Powershell System.Object 中選擇欄位 - Exchange Online PowerShell

  • August 8, 2019

問:我有一個明顯簡單的 PowerShell 系統對象,我很難從中選擇數據。有人可以幫助解釋我如何選擇/擴展此對像中的欄位嗎?

更多資訊:

我已使用 Exchange Online 環境從我的 Exchange Online 環境中選擇了一個對象(公共文件夾)

Get-MailPublicfolder

現在對象儲存在變數 $pf

$pf.getType()

IsPublic IsSerial Name                                     BaseType
-------- -------- ----                                     --------
True     True     ArrayList                                System.Object

當我這樣做時

$pf | fl * 

我得到以下輸出

EmailAddressPolicyEnabled              : False
PrimarySmtpAddress                     : metrowest@company.com
RecipientType                          : PublicFolder
RecipientTypeDetails                   : PublicFolder
DisplayName                            : Metro West

等等。

但是,如果我這樣做

$pf.displayName

或者

$pf | select displayName

我一無所獲

當我這樣做時

$pf | select *

做這個:

$pf = Get-MailPublicfolder

不要這樣做:

$pf = Get-MailPublicfolder | fl
# or
$pf = Get-MailPublicfolder | Format-List

為什麼?當您將結果傳遞給 時Format-List,您最終會得到一個格式化的字元串對象,而不是MailPublicFolderGet-MailPublicfolder. 這就是為什麼你在跑步時會看到那些成員gm

您可以通過這樣做來測試是否退出,並且該對象將具有相同的成員

$a = Get-ChildItem | Format-List
$a | Get-Member

我在我這邊測試,一切正常。 在此處輸入圖像描述
