Pythonnet错误：XamlParseException:'；未能创建'；单击'；从文本中

我以前在IronPython上工作（使用WPF开发一些GUI），最近我开始尝试pythonnet

但是我发现在IronPython上工作的xaml文件在CPython+pythonnet上不工作。在IronPython中，我可以定义一个按钮。在xaml文件中单击，但在CPython中似乎不可能。我试图寻找答案，但没有找到相关的答案。所以希望你能在这里救我

以下是我的主要剧本：

import clr
clr.AddReference(r"wpf\PresentationFramework")
from System.IO import StreamReader
from System.Windows.Markup import XamlReader
from System.Windows import Application, Window
from System.Threading import Thread, ThreadStart, ApartmentState

class MyWindow(Window):
    def __init__(self):
        stream = StreamReader('test.xaml')
        window = XamlReader.Load(stream.BaseStream)
        Application().Run(window)

    def Button_Click(self, sender, e):
        print('Button has clicked')

if __name__ == '__main__':
    thread = Thread(ThreadStart(MyWindow))
    thread.SetApartmentState(ApartmentState.STA)
    thread.Start()
    thread.Join()

下面是test.xmal：

<Window 
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
    Title="WpfApplication1" Height="300" Width="300"> 
    <Grid>
        <Button x:Name="BUTTON" Content="Button" HorizontalAlignment="Left" Margin="101,82,0,0" VerticalAlignment="Top" Width="75" Click="Button_Click" Background="#FFFF1616"/>
    </Grid>
</Window>

非常感谢你的帮助

不能使用pythonnet包在python中导入wpf。但是您可以在PresentationFramework中使用PresentationFramework加载XAML文件，但这有一些限制。XamlReader无法执行事件处理，因此我们可以在python文件中手动添加该按钮的事件，而不是在XAML文件中

听听gui.xaml代码

<Window 
       xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
       xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
       Title="WpfApplication1" Height="300" Width="300">
    <Grid>
        <Label Content="Hello world" HorizontalAlignment="Left" Height="32" Margin="65,77,0,0" VerticalAlignment="Top" Width="119"/>
        <Button Name="button1" Content="Button" HorizontalAlignment="Left" Margin="65,145,0,0" VerticalAlignment="Top" Width="75"/>
    </Grid>
</Window>

是的，它与IronPython一起工作。我刚刚又进行了一次测试，看起来IronPython能够读取您的事件处理程序定义，而python.net却不能。如果在

\uuuu init\uuuu

工作之前单击定义

按钮，您可以尝试一下吗？如果不是这样的话，那么很可能您必须在代码中附加事件处理程序，而不是在xaml中附加事件处理程序。我收到了同样的错误消息。谢谢你的回答。我尝试了一些与你的答案相似的方法，效果很好。谢谢。我还需要从系统导入LogicalTreeHelper和RoutedEventHandler
。Windows导入应用程序，窗口，LogicalTreeHelper，RoutedEventHandler
