不知何故，我的XAML代码无法在PowerShell中运行。

我测试了另一个xaml代码并且工作正常，所以可能与.netframework或PowerShell脚本无关？

但是我的脚本看起来像这样：

＆＃13;
＆＃13; 
#==============================================================================================
# XAML Code - Imported from Visual Studio Express WPF Application
#==============================================================================================
[void][System.Reflection.Assembly]::LoadWithPartialName('presentationframework')
[xml]$XAML = @'

  [XAML CODE HERE]

'@
#Read XAML
$reader=(New-Object System.Xml.XmlNodeReader $xaml) 
try{$Form=[Windows.Markup.XamlReader]::Load( $reader )}
catch{Write-Host "Unable to load Windows.Markup.XamlReader. Some possible causes for this problem include: .NET Framework is missing PowerShell must be launched with PowerShell -sta, invalid XAML code was encountered."; exit}

#===========================================================================
# Store Form Objects In PowerShell
#===========================================================================
$xaml.SelectNodes("//*[@Name]") | %{Set-Variable -Name ($_.Name) -Value $Form.FindName($_.Name)}


#===========================================================================
# Shows the form
#===========================================================================
$Form.ShowDialog() | out-null
＆＃13;
＆＃13;
＆＃13;

我使用Visual Studio 2017生成了XAML，但我认为这并不重要...

提前多多感谢。

您的XML无效。例如，您不能将元素分配给Null。此外，您错过了结束</Window>

我清理了一点XML。它应该加载Powershell
