Powershell驱动的WPF应用程序未执行某些代码（写输出未按预期工作）

创建一个由Powershell支持的WPF向导，以获取输入参数并执行外部脚本。我的想法是将这个脚本放入一个更大的脚本中，该脚本接受输出（布尔值），并基于out执行/不执行。

底部附近部分的

（$ wpf.ConfirmFinish.add_Click）单击完成按钮时，gui将关闭并写入输出。似乎只接受仅与WPF本身相关的命令和参数，并且不会在* add_Checked（）或* add.UnChecked（）方法上更新局部变量。在自己的PS窗口中将$ props设置为$ true或$ false并进行write-Output时，它将从此脚本中产生预期的结果。

[CmdletBinding()]
param (
    [Parameter(Position = 0,
               Mandatory = $true,
               ValuefromPipelineByPropertyName = $true,
               ValuefromPipeline = $true)]
    [Alias("FullName")]
    [System.String[]]$Path

Write-Output $obj

我期望这种格式的管道输出：

    Default App Ass.    : True
    No Office           : False
    Quality Chrome      : True
    Office ProPlus      : True
    No Apps             : False
    Manged No ESET      : False
    Chrome Whitelist    : False
    No Network File Xpl : True
    Office Business     : False
    Nice Start          : True
    Windows Print MGMT  : True
    Standard Apps       : False
    Managed ESET        : True

但是，我没有输出。 Write-Host确实将这些变量正确地写入了控制台，但是Write-Output却不产生任何结果。

我认为这是代码的麻烦所在：

$wpf.ConfirmFinish.add_Click({
    $props = @{ 'Managed ESET' = $wpf.managedE.IsChecked;
                'Manged No ESET' = $wpf.managedNo.IsChecked;
                'Standard Apps' = $wpf.standardApps.IsChecked;
                'No Apps' = $wpf.noApps.IsChecked;
                'Office ProPlus' = $wpf.officePro.IsChecked;
                'Office Business' = $wpf.officeBiz.IsChecked;
                'No Office' = $wpf.noOffice.IsChecked;
                'Quality Chrome' = $wpf.qualityChrome.IsChecked;
                'Default App Ass.' = $wpf.defaultApps.IsChecked;
                'Nice Start' = $wpf.niceStart.IsChecked;
                'Windows Print MGMT' = $wpf.windowsPrint.IsChecked;
                'No Network File Xpl' = $wpf.networkFile.IsChecked;
                'Chrome Whitelist' = $wpf.chromeWhitelist.IsChecked}
    $obj = New-Object -TypeName psobject -Property $props
    Write-Output $obj
    })
