记录经过点，并创建一条新的线

当绘制完成时，执行完成动画并触发响应模式的事件
/// <summary> /// 执行动画 /// </summary> /// <param></param> private void PlayAnimation(bool result, Action callback = null) { Task.Factory.StartNew(() => { this.Dispatcher.Invoke((Action)delegate { foreach (Line l in currentLineList) l.Stroke = result ? rightColor : errorColor; foreach (Ellipse e in ellipseList) if (currentPointArray.Contains(e.Tag.ToString())) e.Fill = result ? rightColor : errorColor; }); Thread.Sleep(1500); this.Dispatcher.Invoke((Action)delegate { foreach (Line l in currentLineList) this.canvasRoot.Children.Remove(l); foreach (Ellipse e in ellipseList) e.Fill = Color; }); currentLine = null; this.currentPointArray.Clear(); this.currentLineList.Clear(); isChecking = false; }).ContinueWith(t => { try { if (callback != null) callback(); } catch (Exception ex) { Console.WriteLine(ex.Message); } finally { t.Dispose(); } }); }
