C#-在事件中更改变量？

在阅读之前，我想指出我是一名在C#工作的高中生，我的大部分学习都是通过互联网完成的

我遇到了一个问题，当我设置

int\u player1\u religation=1pictureBox\u\u单击时，
pictureBox\u\u单击时，它不会保留值（或重置值）。我需要单击一个按钮，然后单击另一个按钮，但是当第二个按钮需要识别它是被单击的第二个按钮时，这两个按钮都被视为第一次单击

我相信问题在于设置整数，但如果是这样的话，我不太确定把它们放在哪里。有什么问题吗？（除了当前的两个按钮（Buhhdism和Taao），还有更多的按钮，但只需点击两次即可声明player1和player2的角色。）

代码：

公共部分类表单2:表单
{
int int_player1_religation=0；//首先，我想鼓励你继续学习！在高中学习C#编程并不容易，因为大多数人在大学或工作中都这样做

不管怎么说，这个问题在你的第二次声明中

int-int-player1\u-religation=1；//您正在创建一个与类作用域同名的局部作用域变量。当作用域发生变化时，局部作用域变量消失。在if语句末尾。如果要设置类变量，只需
int-player2\u-religation=2
，而不是
int-int-player2\u-religation=2；
不要使用
if（x）
后跟
if（！x）
——使用
if（x）{…}else{…}
。
