您可以尝试的一个选项是直接操作控制台缓冲区以呈现您的游戏区域并使用 Console.SetCursorPosition 将光标定位到您使用 Console.ReadLine 的输入行,例如获取用户输入。
由于缓冲区的直接操作不会影响光标位置并且独立于控制台读/写功能,因此您可以有一个线程更新控制台缓冲区,该缓冲区覆盖前 24 行,第 25 行正在等待输入。如果我有时间,我会尝试整理我的意思的示例,但与此同时,您可以参考我提供的其他答案,以获得直接写入控制台缓冲区的指针。
How can I write fast colored output to Console?
Deleting previously written lines in Console
当然,您会想编写一些不错的包装函数来使其易于使用,我一直在考虑这样做,我只是没有在控制台上做足够的工作,所以我真的要下来做点什么。
更新:添加了一个在线程中更新控制台同时仍接受用户输入的小示例。只需键入“退出”即可停止运行。请注意,ConsoleBuffer 类并不理想,我没有关闭控制台句柄,它只是演示的一小段代码。
