Powershell WPF事件更新

如何解决Powershell WPF事件更新

我在更新WPF窗口窗体时遇到问题。 基本上，我想根据当前连接的Network-SSID在“ Console-TextBox”中触发不同的内容。

    [xml]$xaml = Get-Content -Path $PSScriptRoot\Pattern.xaml
    $manager = New-Object System.Xml.XmlNamespaceManager -ArgumentList $xaml.NameTable
    $manager.AddNamespace("x","http://schemas.microsoft.com/winfx/2006/xaml");
    $xamlReader = New-Object System.Xml.XmlNodeReader $xaml
    [Windows.Markup.XamlReader]::Load($xamlReader)
}
$window = Load-Xaml

$textbox = $window.FindName("textbox")
$textbox_console = $window.FindName("textbox_console")
Get-EventSubscriber | Unregister-Event
Register-EngineEvent -SourceIdentifier 'MyEvent' -Action {$textbox_console.Text += "ManualInput"}


$networkChange = [System.Net.NetworkInformation.NetworkChange];
Register-ObjectEvent -InputObject $networkChange -EventName NetworkAddressChanged -SourceIdentifier NetworkChanged -Action {
    $textbox_console.Text += "`nNetworkChanged"
}

$textbox.Add_TextChanged({
    
    New-Event -SourceIdentifier 'MyEvent'
})

$window.ShowDialog() | Out-Null

XAML：

<Window
  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
  Title="Pattern" Width="600" Height="400" WindowStyle="None" ResizeMode="NoResize"  
    WindowStartupLocation="CenterScreen">
    <StackPanel>
    <TextBox x:Name="textbox" HorizontalAlignment="Left" Height="70" Margin="124,104,0" TextWrapping="Wrap" Text="TextBox" VerticalAlignment="Top" Width="262"/>
    <TextBox x:Name="textbox_console" HorizontalAlignment="Left" Height="70" Margin="124,0" TextWrapping="Wrap" Text="console" VerticalAlignment="Top" Width="262"/>
    </StackPanel>
</Window>

我是事件处理的新手，不确定这个问题是由线程/进程处理还是错误的事件处理引起的...

也许有人可以指出一些提示并告诉我，如何使用NetworkChange-Event更新文本框的文本？
