为什么我的标签不可点击?

标签: c# label

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" Form"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:

    /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
    protected override void Dispose(bool disposing)
    {
        if (disposing && (components != null))
        {
            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
