c# - 剪刀石头布c#登场如何显示胜率？

Question

我最近开始制作一个 RPS 游戏机应用程序，它运行良好，我决定给自己更多的挑战，并决定如果它对计算机和玩家都有赢率并且由于某种原因它没有显示赢率，那将会很酷左侧的费率编辑:所以我让它向左显示，但百分比仍为 0 知道如何解决这个问题吗？

Answer 1

首先，我认为递增逻辑存在问题，无法递增参与者对象的实际值。 playerWins 和 computerWins 是您的 main 的局部变量，并被视为新变量，而不仅仅是您的参与者对象的引用。更改以下行:

1. playerWins++ to player.wins++//改变参与者的实际值
2. computerWins++ 到 comp.wins++

接下来，你什么时候说左？您具体想要什么格式？现在尝试以下几行:

1. string _winRate = string.Format("玩家获胜率:{0}%", winRate);
