因此，我正在尝试使用asp.net创建一个垄断性网络游戏。由于回发，我在保存变量方面遇到了问题，因此我创建了一个数据库，该数据库存储了有关球员和方格等的所有信息。但是，由于某些原因，我现在遇到的问题是当前的球员ID是“不能正确存储/检索。对于较长的代码墙，我深表歉意；

据我所知，我拥有的数据库代码可以正常工作，因为我可以继续游戏，并且它将玩家位置设置为他们之前所在的正方形。但是出于某种原因，开始游戏时总是轮到玩家2了，而changeActivePlayer（）似乎并没有采取任何措施。我逐行浏览了代码，单击EndTurnButton之后，playerID发生了变化，但是从数据库中获取值时，它又回到了玩家2的ID。我也不确定为什么默认它是玩家2，就像当我调用开始游戏功能时，我将当前玩家设置为玩家[0]一样，所以肯定是玩家1吗？任何帮助，将不胜感激。
