现在我被卡住了，从这一点开始，我该如何在画布上画出身体每个关节之间的‘骨头'，类似于我如何为关节添加日食？。
如有任何帮助，不胜感激
在drawbody（Body Body)函数中，需要设置要绘制的“骨头”。例如：
private void DrawBody(Body body)
{
// left forearm
DrawBone(body.Joints[JointType.HandLeft], body.Joints[JointType.ElbowLeft]);
// right forearm
DrawBone(body.Joints[JointType.HandRight], body.Joints[JointType.ElbowRight]);
// ...etc...
}
drawbone(Joint，Joint)函数如下所示：
private void DrawBone(Joint first, Joint second)
{
Line line = new Line();
line.Stroke = Brushes.LightSteelBlue;
line.X1 = first.Position.X;
line.X2 = second.Position.X;
line.Y1 = first.Position.Y;
line.Y2 = second.Position.Y;
line.StrokeThickness = 2;
myCanvas.Children.Add(line);
}
我在内存中工作，所以语法可能会有点问题。
