为什么我的标签无法点击?

How come my label is unclickable?

我正在尝试用 c# 创建一个项目,主要是一个记忆游戏。一切进展顺利,直到我遇到一个我没有见过其他人遇到过的问题,这让我很困惑,因为我认为我没有做任何非常复杂的事情。在我的 "Form" 上有 16 个标签,所有标签都有一个点击方法。当我运行我的程序时,点击部分永远不会发生。这些按钮工作正常,当它们在标签上单击 on.But 时开始逐行调试它什么都不做,从不调用 it.Here 可能需要一些东西:

我假设你的标签在你尝试点击它之前被隐藏了

如果 属性 Visible 设置为 false,控件将不会触发事件 Click

如果你想show/hidden通过点击来控制,那么尝试在控件中使用背景颜色或图片。
Hidden - 没有 picture/transparent
Visible - 将显示图片或一些背景颜色
