如何在 XAML 中实现如下所示的圆形按钮

How to implement a circle button like below one in XAML

我正在 XAML 上开发逻辑连接器,但在生成过程中遇到了困难 AND 连接器

代码:

    <Grid> 
       <Ellipse Stroke="Red" StrokeThickness="1" Fill="Black"></Ellipse>   
       <Button> <TextBlock VerticalAlignment="Center" HorizontalAlignment="Center" Foreground="Black" >+</TextBlock> </Button>      
       <Ellipse Stroke="Black" StrokeThickness="1" Margin="5"> </Ellipse> 
</Grid>

添加路径数据终于得到答案

<Grid >
                    <Ellipse HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Stroke="Black" StrokeThickness="1" />
                    <Path Data="M10,0 L10,20 z" Stroke="Black" StrokeThickness="1" Stretch="Fill"  />
                  <Path Data="M0,10 L20,10 z" Stroke="Black" StrokeThickness="1" Stretch="Fill"  />
                </Grid>
