语法 c# 的问题，无法使用 ojects/call get、set、

Question

我是 C# 的新手，一直在鬼屋中从事迷宫游戏的项目 context.After 研究不同的方法我决定使用对象和链表。然而，尽管尝试了数周，但我仍在努力编写代码，并且在阅读文章和观看在线教程数小时后，我已经达到了我现在比以往任何时候都更加困惑的地步。我想使用这种方法而不是数组，因为我觉得这样更高效且更面向对象。 我正在考虑使用一个简单的 if/else 结构，但对于这种级别的编码，我觉得它太混乱了。 任何帮助、建设性的批评或想法将不胜感激，因为我不想在花了这么多时间后放弃，但我觉得它已经到了那个地步。到目前为止，这是我的代码。 提前致谢:)

您创建了一个没有 main() 的 class 对象。一个项目只有一个主。因此，您要么需要将 Room 设为应用程序中的 main()，要么从 Room Class 中删除 main 方法。请参阅下面的代码以了解更改。
