Question

C#下面的MouseEnter事件和MouseLeave事件为什么不能真正触发，也就是语句下面是这样写，但不会弹出来

还有，button控件能使用MouseEnter事件和MouseLeave事件吗？
private void button2_MouseEnter(object sender, EventArgs e)
{
if (stage_Number == 1)
{
pictureBox1.Location = new System.Drawing.Point(72, 378);
label1.Location = new System.Drawing.Point(81, 387);
pictureBox1.Visible = true;
label1.Visible = true;
label1.Text = "同级别的较量！";
}
}
private void button2_MouseLeave(object sender, EventArgs e)
{
pictureBox1.Visible = false;
label1.Visible = false;

Answer 1

private void button1_MouseEnter(object sender, EventArgs e)
{
label1.Text = "enter";
}
private void button1_MouseLeave(object sender, EventArgs e)
{
label1.Text = "leave";
}

可以实现

就不能加if和修改Visible属性的语句吗？
