我试图用XAML在C＃中制作康威的生命游戏。该窗口允许用户使用滑块指定我的2D单元格数组的行数和列数。当我的Uniform Grid是一个完美的正方形（10x10,20x20甚至16x16）时，模拟工作没有问题。然而，当用户试图指定矩形均匀网格（13x14,15x26,24x14）时，细胞被差异抛出（即在33x27网格中，差异= 6，因此细胞适当向上，但被抛弃（左/右）差异）。我已经缩小了，这只发生在x轴上;细胞永远不会在y轴上脱落。 问题：为什么我的阵列会脱离x轴？这有什么问题吗？
据我所知，一切都应该正常。我设置了一个日志来检查我的2D数组和我的统一网格的尺寸。我不确定出了什么问题，我一直在为DAYS盯着调试。我的智慧结束了。请帮助，我希望有一些我根本没有抓到的东西。
代码图例： unigridOfCells是XAML中的统一网格。 slideWidth / slideHeight是滑块。 另外，我使用的资源转换器将我的isAlive属性转换为SolidColorBrush。

private Cell[,] nextGenCells;

答案 0 :(得分：1)
问题在于，您创建单元格的顺序与UniformGrid排列其子项的顺序不同。
在您的setCellsOnGrid方法中，您可以从上到下创建单元格，然后从左到右创建单元格，而UniformGrid按顺序从左到右排列，然后从上到下排列汉字。
对于方形网格，网格第一列中的单元格在UniformGrid的第一行中绘制，对于其他列和行也是如此。您最终将网格反映在x = y行中。但是，对于非方形网格，行的长度不等于列的长度，因此网格完全不合适。
例如，对于3×3网格，您的循环按以下顺序运行：
1 4 7
2 5 8
3 6 9
但是，控件按以下顺序添加到UniformGrid（假设您尚未设置FlowDirection="Right"）：
1 2 3
4 5 6
7 8 9
对于3×4网格，您的循环按顺序
运行1 5 9
2 6 10
3 7 11
4 8 12
但控件按顺序
添加到UniformGrid
1 2 3
4 5 6
7 8 9
10 11 12
这意味着cells数组中相邻的单元格可能不会在UniformGrid中被绘制为相邻，反之亦然。
幸运的是，修复很简单：在i中切换j和setCellsOnGrid循环的顺序。使j循环为外循环，i循环为内循环。
顺便提一下，您的blockSpace方法似乎没有使用i和j循环变量 - 它只调用相同的方法codeColumn * codeRow次。这是故意的吗？
