WPF GUI to powershell

Question

不知何故，我的XAML代码在PowerShell中不起作用。

<Window
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

</Grid>

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

但是我的脚本看起来像这样：

#==============================================================================================
# 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

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

提前非常感谢。

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

我稍微清理了一下你的XML。它应该加载在Powershell中

[void][System.Reflection.Assembly]::LoadWithPartialName('presentationframework')
#Build the GUI
[xml]$xaml = @"
