问题 [I created a DrawingLine animation class to draw patterns. The constructor starts the process of creating and animating lines: internal DrawingLine(double x, double y, int _thickness, Brush _brush, Canvas _canvas) At the end of the animation, this method generates a new line: 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
