我试图在c＃中创建一个项目，主要是一个记忆游戏。这一切都很顺利，直到我遇到了一个我没见过其他人的问题，这真让我感到困惑，因为我不认为我做了一件非常复杂的事情。在我的＆＃34; Form＆＃34;是16个标签，点击时都有一个方法。当我运行我的程序时，点击部分永远不会发生。按钮工作正常，点击它们时开始逐行调试。但是在标签上它只是什么都不做，从不调用它。这里有一些可能需要的东西：

components.Dispose();

我认为您的标签在尝试点击之前已隐藏
如果属性Click设置为Visible，则控件不会触发事件false。
如果要通过单击显示/隐藏控件，请尝试在控件中播放背景颜色或图片
Hidden - 没有图片/透明
Visible - 将显示图片或一些背景颜色
