c# - C# WinForm 二维数组

Question

我是 C# 的初学者。我需要专业的帮助。首先，我有像 C# WindowsForm 代码这样的动态数组代码。这个程序是用代码编写的，没有使用 Form。

程序的运行原理是在当前代码状态下使用上下左右方向键从(0,0)点到(9,9)点。

问题 1. 每当我使用箭头键上下左右移动坐标时，我想在按钮上制作一个红色边框，但我不知道怎么做。

问题2。例如，在点（0,0），我想让它只移动到右边和底部。同样，在 (2,0) 点，它应该设置为不能只向上移动。

问题 3. 我想实现 20 颗炸弹随机撒在中间，如果炸弹被踩到，则会显示一条适当的消息并初始化为 (0,0) 点。

谢谢你。
