How can I draw a circle like this, 2 colors in 2 parts. I'm coding in xaml
我怎样才能画一个这样的圆圈，2 种颜色的 2 部分。我正在用 xaml 编码
<Ellipse Fill="White" HorizontalAlignment="Center" VerticalAlignment="Center" Width="300" Height="300">
</Ellipse>
<Path VerticalAlignment="Top" Fill="Brown" HorizontalAlignment="Left">
<Path.Data>
<PathGeometry>
<PathFigure StartPoint="59,150">
<ArcSegment SweepDirection="Clockwise" Size="141,80" Point="341,150"/>
</PathFigure>
</PathGeometry>
</Path.Data>
</Path>

Here ya go:
给你：
<Canvas>
<Ellipse Canvas.Left="50" Canvas.Top="50" Width="300" Height="300" Stroke="Black" StrokeThickness="1" Fill="Red" />
<Ellipse Canvas.Left="50" Canvas.Top="50" Width="300" Height="300" Stroke="Black" StrokeThickness="1" Fill="Yellow">
<Ellipse.Clip>
<RectangleGeometry Rect="0 100 300 300" />
</Ellipse.Clip>
</Ellipse>
<Rectangle Canvas.Left="50" Canvas.Top="150" Width="300" Height="200" Stroke="Black" StrokeThickness="1" Fill="Transparent">
<Rectangle.Clip>
<EllipseGeometry Center="150, 50" RadiusX="150" RadiusY="150" />
</Rectangle.Clip>
</Rectangle>
</Canvas>
The first canvas element draws a red circle, the second element draws a yellow circle over top and clips it, the third element draws the black line through the middle. Here's the result:
第一个画布元素绘制一个红色圆圈，第二个元素在顶部绘制一个黄色圆圈并将其剪辑，第三个元素绘制穿过中间的黑线。结果如下：
EDIT: Actually thinking about this some more the two ellipses can be done with a single ellipse and a linear gradient brush:
编辑：实际上再考虑一下这两个椭圆可以用一个椭圆和一个线性渐变画笔来完成：
<Ellipse Canvas.Left="50" Canvas.Top="50" Width="300" Height="300" Stroke="Black" StrokeThickness="1">
<Ellipse.Fill>
<LinearGradientBrush StartPoint="0,0" EndPoint="0,1">
<GradientStop Color="Red" Offset="0.3333" />
<GradientStop Color="Yellow" Offset="0.3333" />
</LinearGradientBrush>
</Ellipse.Fill>
</Ellipse>

You can also make use of the following...
您还可以使用以下...
<Grid Height="200" Width="200" VerticalAlignment="Center">
<Ellipse Fill="#FFE1B631" />
<Path Data="M93.88768,0 C136.17198,0 172.32661,26.244247 186.95134,63.33252 L187.77536,65.5 0,65.5 0.82401276,63.33252 C15.44875,26.244247 51.603378,0 93.88768,0 z" Fill="#FFFD450F" Height="60.26" Stretch="Fill" VerticalAlignment="Top" Margin="8,1.31,8,0"/>
</Grid>
