UWP - InkCanvas上的InkToolbar上的自定义撤消和重做 - System.ExecutionEngineException未处理

Question

尝试在InkCanvas上创建自定义撤消和重做。然而，经过一些压力测试（添加大量笔画，撤消和重做很多次），应用程序崩溃：

  

System.ExecutionEngineException未处理。的HResult = -2146233082

在我的AddToRedoList方法的foreach循环上。任何人都有任何想法如何捕获和修复异常？

private void AddToRedoList(InkStroke addStroke) {
  var addInkPoint = addStroke.GetInkPoints();
  var addInkPointList = new List<InkPoint>();
  foreach (var point in addInkPoint) {
    addInkPointList.Add(new InkPoint(point.Position, point.Pressure));
  }

  redoCustomStrokeList.Add(new CustomStroke() {
    InkPoints = addInkPointList,
    DrawingAttributes = addStroke.DrawingAttributes
  });
}

private void UndoOnClick(object sender, RoutedEventArgs e) {
  var allStrokes = InkImage.InkPresenter.StrokeContainer.GetStrokes();
  var undoStroke = allStrokes[allStrokes.Count - 1];
  AddToRedoList(undoStroke);

  allStrokes[allStrokes.Count - 1].Selected = true;
  InkImage.InkPresenter.StrokeContainer.DeleteSelected();
}

private void RedoOnClick(object sender, RoutedEventArgs e) {
  var lastRedoInkPoints = redoCustomStrokeList[redoCustomStrokeList.Count-1];
  InkImage.InkPresenter.StrokeContainer.AddStroke(CreateStroke(lastRedoInkPoints));
    redoCustomStrokeList.Remove(lastRedoInkPoints);
  }
}
