c# - 按钮单击方法不起作用，因为它的可见性发生变化

Question

我有一个图片框(称为 pic_Image)和 2 个按钮(称为 btn_AddImage 和 btn_RemoveImage)。我想让按钮在用户将鼠标移到 pic_Image 上时可见，并在鼠标离开 pic_Image 时使它们不可见。这是使可见的代码:

private void pic_Image_MouseMove(object sender, MouseEventArgs e)
    {
        btn_AddImage.Visible = true;
        btn_RemoveImage.Visible = true;
    }

这是隐藏的代码:

private void pic_Image_MouseLeave(object sender, EventArgs e)
    {
        btn_AddImage.Visible = false;
        btn_RemoveImage.Visible = false;
    }

问题是在我使用 pic_Image_MouseMove 方法后，Onbutton click 方法不起作用。

提前致谢

鼠标电影事件不断触发，直到鼠标在图片上用鼠标输入替换鼠标移动

private void pic_Image_MouseEnter(object sender, MouseEventArgs e)
{
    btn_AddImage.Visible = true;
    btn_RemoveImage.Visible = true;
    if (pic_Image.Image != null)
        btn_RemoveImage.Visible = true;
}
