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，它运行良好，所以可能与 .netframework 或 PowerShell 脚本无关？
但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我使用 Visual Studio 2017 生成了 XAML，但我认为这并不重要...
非常感谢。
问候， 罗宾 ;-)
【问题讨论】：
-
won't work- 你必须更具体 - 什么不起作用，它应该以什么方式起作用？你的问题都不清楚。 -
您可以简单地调用： $Form=[Windows.Markup.XamlReader]::Load( $reader ) 并查看您在 XAML 解析中的异常... t 帮助您调试
-
删除所有像这样设置的属性：
="{Null}"，或为它们分配一个有效值。
