C#总是假布尔

Question

有人可以帮忙吗？我无法理解为什么当我按下按钮7时bool floorOne总是设置为false,即使我先按下button3或button1.这应该是一个相当简单的问题,只有在初始化时,按下button2或按下button4时才会出错.我不知道它是如何回归虚假的.

它可能有一个相对简单的解决方案,但我找不到它,谢谢你的时间.

编辑:当我调试时,它显示为false,我不知道这些信息是否会有所帮助.我知道很多代码可能不需要包含在这里,但是为了防止出现问题,我想我应该添加它.

编辑2:太棒了,非常感谢大家!

因为在某些方法中,您声明了一个新 floorOne变量,而不是修改现有的Form1字段.

更换

bool floorOne = true;

同

floorOne = true;
