Combine two Path figures in one?
提问by Andrei Neculai
I'm having these two shapes:
我有这两种形状：
Fist picture code:
拳头图片代码：
<Path Fill="Orange">
<Path.Data>
<PathGeometry>
<PathFigure StartPoint="0,100">
<BezierSegment Point1="50,110" Point2="50,110" Point3="100,100"></BezierSegment>
<LineSegment Point="100,80"></LineSegment>
<LineSegment Point="120,90"></LineSegment>
<LineSegment Point="120,70"></LineSegment>
<LineSegment Point="100,60"></LineSegment>
<LineSegment Point="100,20"></LineSegment>
<LineSegment Point="80,0"></LineSegment>
<LineSegment Point="20,0"></LineSegment>
<LineSegment Point="0,20"></LineSegment>
<LineSegment Point="0,40"></LineSegment>
<LineSegment Point="-20,20"></LineSegment>
<LineSegment Point="-20,40"></LineSegment>
<LineSegment Point="0,60"></LineSegment>
</PathFigure>
</PathGeometry>
</Path.Data>
</Path>
Second picture code:
第二张图片代码：
<Path Fill="Orange">
<Path.Data>
<PathGeometry>
<PathFigure>
<LineSegment Point="0,25"></LineSegment>
<LineSegment Point="250,25"></LineSegment>
<LineSegment Point="250,0"></LineSegment>
</PathFigure>
</PathGeometry>
</Path.Data>
</Path>
How do i combine them for something like this(ignore the text):
我如何将它们组合成这样的（忽略文本）：
I need this to be done in C# ( not xaml ). Thanks!
我需要在 C# （不是 xaml ）中完成这项工作。谢谢！

Basically, you can use a CombinedGeometryobject to do this:
基本上，您可以使用CombinedGeometry对象来执行此操作：
<Path Stroke="Black" StrokeThickness="1" Fill="#CCCCFF">
<Path.Data>
<!-- Combines two geometries using the exclude combine mode. -->
<CombinedGeometry GeometryCombineMode="Union">
<CombinedGeometry.Geometry1>
<PathGeometry>
<PathFigure StartPoint="0,100">
<BezierSegment Point1="50,110" Point2="50,110" Point3="100,100"></BezierSegment>
<LineSegment Point="100,80"></LineSegment>
<LineSegment Point="120,90"></LineSegment>
<LineSegment Point="120,70"></LineSegment>
<LineSegment Point="100,60"></LineSegment>
<LineSegment Point="100,20"></LineSegment>
<LineSegment Point="80,0"></LineSegment>
<LineSegment Point="20,0"></LineSegment>
<LineSegment Point="0,20"></LineSegment>
<LineSegment Point="0,40"></LineSegment>
<LineSegment Point="-20,20"></LineSegment>
<LineSegment Point="-20,40"></LineSegment>
<LineSegment Point="0,60"></LineSegment>
</PathFigure>
</PathGeometry>
</CombinedGeometry.Geometry1>
<CombinedGeometry.Geometry2>
<PathGeometry>
<PathFigure StartPoint="0,100">
<LineSegment Point="0,25"></LineSegment>
<LineSegment Point="250,25"></LineSegment>
<LineSegment Point="250,0"></LineSegment>
</PathFigure>
</PathGeometry>
</CombinedGeometry.Geometry2>
</CombinedGeometry>
</Path.Data>
</Path>
Please take a look at the How to: Create a Combined Geometrypage on MSDN for full details.
请查看MSDN上的“如何：创建组合几何”页面以获取完整详细信息。
Please also note that you will need to set the StartPointproperty of these PathFigureobjects to correctly line up your shapes.
另请注意，您需要设置StartPoint这些PathFigure对象的属性以正确排列您的形状。

Sorry, I didn't notice that you wanted to use code. In code you would have to name your PathGeometryobjects and put them into a Resourcessection:
抱歉，我没注意到您想使用代码。在代码中，您必须命名PathGeometry对象并将它们放入一个Resources部分：
<Application.Resources>
<PathGeometry x:Key="Shape1">
...
</PathGeometry>
<PathGeometry x:Key="Shape2">
...
</PathGeometry>
</Application.Resources>
Then you can still use a CombinedGeometryobject:
然后你仍然可以使用一个CombinedGeometry对象：
PathGeometry shape1 = (PathGeometry)Application.Current.FindResource("Shape1");
PathGeometry shape2 = (PathGeometry)Application.Current.FindResource("Shape2");
CombinedGeometry combinedGeometry = new CombinedGeometry(
GeometryCombineMode.Union, shape1, shape2);
Path combinedPath = new Path();
combinedPath.Data = combinedGeometry;
Please take a look at the CombinedGeometry Classpage at MSDN for more information with this method.
请查看MSDN上的CombinedGeometry Class页面以获取有关此方法的更多信息。
