C# 如何在windows phone画布中动态绘制类似风扇的圆圈？
我已经问过问题了，说如何画这种圆，但问题被保留了下来，我想我并没有描述太多关于那个圆的内容C# 如何在windows phone画布中动态绘制类似风扇的圆圈？,c#,silverlight,windows-phone,C#,Silverlight,Windows Phone,我已经问过问题了，说如何画这种圆，但问题被保留了下来，我想我并没有描述太多关于那个圆的内容 基本上，这是一个有四种颜色组合的圆圈，还有一组看起来像扇形的圆圈，希望我能得到答案，我也在尝试，如果问题解决了，我会自己回答，这样也能帮助其他人。虽然我的代码看起来太长，这可能不是正确的解决方案，但给出了我想画的确切数字 首先我画四等分，这个代码画第一个四等分 PathFigure pthFigure1 = new PathFigure(); pthFigure1.Star

您可以大大简化代码。图形的四个彩色部分都是相同的，轮廓由三个拱门定义。绘制每个零件的不同之处在于定义点和颜色：

arcSeg2.Point = point3;
arcSeg2.Size = new Size(radius, radius);
arcSeg2.SweepDirection = SweepDirection.Counterclockwise;
ArcSegment arcSeg3 = new ArcSegment();
arcSeg3.Point = point1;
arcSeg3.Size = new Size(radius/2, radius/2);
