Wpf 现代图形用户界面+；powershell=System.Windows.Markup.StaticResourceHolder

我想在Powershell上使用ModernWPUI主题。 一般来说，为了更好的GUI，我在powershell中只使用XAML，所以我真的不知道太多 现在，这是我的测试代码：

XAML（test.XAML）：

结果:

MethodInvocationException: (path)\run.ps1: 15: 1
Line |
  15 | $ Form = [Windows.Markup.XamlReader] :: Load ($ Reader)
     | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
     | Exception calling "Load" with arguments "1": "An exception was thrown when specifying a value on 'System.Windows.Markup.StaticResourceHolder'."

Invalid operation: (path)\run.ps1: 22: 1
Line |
  22 | $ Form.ShowDialog ()
     | ~~~~~~~~~~~~~~~~~~
     | A method cannot be called on a null-valued expression.

我尝试在“clr namespace:ModernWpf；assembly=ModernWpf”中编辑或添加它，结果相同

[System.Reflection.Assembly]::LoadWithPartialName('presentationframework')      | out-null
[System.Reflection.Assembly]::LoadFrom('.\assembly\ModernWpf.dll')              | out-null
[System.Reflection.Assembly]::LoadFrom('.\assembly\ModernWpf.Controls.dll')     | out-null
[System.Reflection.Assembly]::LoadFrom('.\assembly\System.ValueTuple.dll')      | out-null

function LoadXml ($global:filename)
{
    $XamlLoader=(New-Object System.Xml.XmlDocument)
    $XamlLoader.Load($filename)
    return $XamlLoader
}

$XamlMainWindow=LoadXml("test.xaml")
$Reader=(New-Object System.Xml.XmlNodeReader $XamlMainWindow)
$Form=[Windows.Markup.XamlReader]::Load($Reader)
$Global:Current_Folder =(get-location).path 


$Form.ShowDialog() 

MethodInvocationException: (path)\run.ps1: 15: 1
