如何从其他线程更新PowerShell GUI文本框？

我尝试了多种代码变体，但均未成功：GUI出现冻结，且文本框无法写入和更新。我不确定为何该线程操作仍会导致UI冻结（我曾在网上看到一些使用XAML同步哈希的示例，但不想采用）。以下是适用于所有控件的可行解决方案：

function getAllControls()
{
    param(
        [System.Windows.Forms.Control]$ParentControl
    )
    $controls = @()
    foreach ($control in $ParentControl.Controls) {
        $controls += $control
        if ($control.Controls.Count -gt 0) {
            $controls += getAllControls -ParentControl $control
        }
    }
    return $controls
}

$btnTest2_Click = {

            $controls = getAllControls -ParentControl $Form;

            $rs = [runspacefactory]::CreateRunspace([initialsessionstate]::CreateDefault2())
            $rs.Open()
            $rs.SessionStateProxy.SetVariable('controls', $controls)
            $instance = [powershell]::Create().AddScript({
                $listBox = $controls | where {$_.Name -eq "myListBox"}
                if ($listBox -ne $null)
                {
                    [Console]::WriteLine($listBox.Name);
                }
                else
                {
                    [Console]::WriteLine("listBox -eq null");
                }

                $ran = [random]::new();
                $ceiling = 10;
                $index = 0;
                while($index -lt $ceiling) {
                    $ranNext = $ran.Next();
                    [Console]::WriteLine($ranNext);
                    Start-Sleep 1
                    $listBox.Items.Add($ranNext);
                    $index++;
                }
            })

            $instance.Runspace = $rs;
            $instance.BeginInvoke();

    }

旧代码示例 #

$helperThread = {
            
            for ($i = 0; $i -lt 10; $i++)
            {

                $form.Invoke([Action]{
                    $tbxTest2Box.Text = "$($i). Updated from helper thread!"
                    [System.Windows.Forms.Application]::DoEvents();
                })

                Sleep -Seconds 1;
            }
        }

        # Start the helper thread
        $runspace = [runspacefactory]::CreateRunspace()
        $runspace.ApartmentState = "STA"
        $runspace.Open()
        $powershell = [powershell]::Create().AddScript($helperThread)
        $powershell.Runspace = $runspace
        $handle = $powershell.BeginInvoke()


        $powershell.EndInvoke($handle)
        $powershell.Dispose()
        $runspace.Close()
