WPF。图案动画class

Question

[我创建了一个 DrawingLine 动画 class 来绘制图案。

构造函数开始创建和动画线条的过程：

internal DrawingLine(double x, double y, int _thickness, Brush _brush, Canvas _canvas)

在动画结束时，此方法生成一个新行：

void CreateNewLine(object sender, EventArgs e)
        {
            Line newLine = new Line();

            switch (lines.Count % 2 == 0)
            {
                case true:
                    {
                        if (lines.Count < 18)
                        {
                                    newLine.X1 = 0;
                                    newLine.Y1 = 180 - offset;
                                    newLine.X2 = 0;
                                    newLine.Y2 = 180 - offset;
                        }

                        //   ...   <-- Here is the math determines the positions of the points of the line

        }

该方法产生动画：

void AnimateXY()
        {
            DoubleAnimation lineXAnimation = new DoubleAnimation();
            lineXAnimation.From = CurrentLine.X1;
            lineXAnimation.To = to_X;
            lineXAnimation.Duration = TimeSpan.FromSeconds(duration);

            DoubleAnimation lineYAnimation = new DoubleAnimation();
            lineYAnimation.From = CurrentLine.Y1;
            lineYAnimation.To = to_Y;
            lineYAnimation.Duration = TimeSpan.FromSeconds(duration);
            lineYAnimation.Completed += CreateNewLine;

            CurrentLine.BeginAnimation(Line.X2Property, lineXAnimation);
            CurrentLine.BeginAnimation(Line.Y2Property, lineYAnimation);
        }

问题：循环此动画的最佳方式是什么，这样就不会出现内存泄漏？我还想听听有关改进此类 classes 结构的一般建议。附上图案图片。]1

我找到了问题的答案。如果class里面全是动画，那么它就支持递归调用（递归创建）。一个递归调用让动画无限循环
