如何在不使用 .format.ps1xml 檔案的情況下強制輸出到自訂 PSObject 的「Format-Table」？

如何在不使用 .format.ps1xml 檔案的情況下強制輸出到自訂 PSObject 的「Format-Table」？

我知道我可以MyCustomPSObject透過產生和載入MyCustomPSObject.format.ps1xml文件來定義格式。

而且我已經看到了人們從 .ps1-script 檔案內部即時產生格式檔案。（也從這裡開始列在句子下面“所以我寫了一個名為 Get-ProcessTotal 的高級 PowerShell 函數”從第 145 行開始.)

而且，據我了解，此格式化文件中的第一個條目用作預設值。

產生該外部文件對我來說似乎很麻煩。

問題：

  • 有沒有辦法在不產生和載入外部文件的情況下執行此操作？

我想要的只是“將其輸出為表格”。 （基本上運行它，Format-Table但在此過程中不會失去物件性。）

腳本 Get-VSSWriters.Current-Version.ps1

這是有問題的腳本：

# This script lists VSS writers.
# The original, uncustomized, version was taken from here:
# https://gallery.technet.microsoft.com/scriptcenter/Powershell-ScriptFunction-415e9e70

$RawWriters = Invoke-Command -ErrorAction Stop -ScriptBlock {
    #Requires -RunAsAdministrator 
    return (VssAdmin List Writers)
} 


# We don't really care about "WriterID" and "WriterInstanceID", so we leave them out of the default 
# display set. (Approach copied from here:
# https://learn-powershell.net/2013/08/03/quick-hits-set-the-default-property-display-in-powershell-on-custom-objects/ )
$defaultDisplaySet = 'WriterEnum', 'WriterName', 'StateID', 'StateDesc', 'LastError'
$defaultDisplayPropertySet = New-Object System.Management.Automation.PSPropertySet('DefaultDisplayPropertySet', [string[]]$defaultDisplaySet)
$PSStandardMembers = [System.Management.Automation.PSMemberInfo[]]@($defaultDisplayPropertySet)


$Writers = @()
for ($i=0; $i -lt (($RawWriters.Count)-3)/6; $i++) {
    $Writer = New-Object -TypeName psobject
    $Writer.PSObject.TypeNames.Insert(0, 'MyVSSWriter')
    $Writer | Add-Member MemberSet PSStandardMembers $PSStandardMembers

    $Writer| Add-Member "WriterEnum" ($i + 1)

    # Note: We split on both single quotes and double quotes.
    # That way this script will work for both:
    # * the English language version of Windows (>>Writer name: 'WMI Writer'<<) 
    # * the German version of Windows (>>Verfassername: "WMI Writer"<<)
    $Writer| Add-Member "WriterName" $RawWriters[($i*6)+3].Split("`"'")[1]

    $Writer| Add-Member "WriterID" $RawWriters[($i*6)+4].Split('{}')[1]
    $Writer| Add-Member "WriterInstanceID" $RawWriters[($i*6)+5].Split('{}')[1]

    $Writer| Add-Member "StateID"   $RawWriters[($i*6)+6].Split('[]')[1]
    $Writer| Add-Member "StateDesc" $RawWriters[($i*6)+6].Split('[]')[2].SubString(1)
    $Writer| Add-Member "LastError" $RawWriters[($i*6)+7].Split(':')[1].Substring(1)

    $Writers += $Writer 
}

$Writers

實際產量

PS C:\> .\Get-VSSWriters.Current-Version.ps1 | select -first 1
WriterEnum : 1
WriterName : Task Scheduler Writer
StateID    : 1
StateDesc  : Stable
LastError  : No error

所需輸出

PS C:\> .\Get-VSSWriters.Updated-Version.ps1 | select -first 1
WriterEnum WriterName            StateID StateDesc LastError
---------- ----------            ------- --------- ---------
         1 Task Scheduler Writer 1       Stable    No error

（這應該與 相同.\Get-VSSWriters.Current-Version.ps1 | select -first 1 | Format-Table。）
