Вывести функцию пространства выполнения PowerShell в текстовое поле WPF

/ 01 ноября 2018

У меня проблемы с получением функции "sync-folder" для вывода в текстовое поле во время его работы. Я пытался просмотреть множество руководств по сети, включая поиск здесь, и я не могу понять это. Я надеюсь, что кто-то, кто понимает это лучше меня, сможет показать мне, как это сделать, в моем тестовом примере ниже: 

$Global:syncHash = [hashtable]::Synchronized(@{})
$newRunspace =[runspacefactory]::CreateRunspace()
$newRunspace.ApartmentState = "STA"
$newRunspace.ThreadOptions = "ReuseThread"
$newRunspace.Open()
$newRunspace.SessionStateProxy.SetVariable("syncHash",$syncHash)

# Load WPF assembly if necessary
[void][System.Reflection.Assembly]::LoadWithPartialName('presentationframework')

$psCmd = [PowerShell]::Create().AddScript({
    [xml]$xaml = @"

    </Grid>
