说错了，不是改变，是可以调节的那种！
public partial class Form3 : Form
{
double time = 0;
bool p1 = true, p2 = false;
public Form3()
{
InitializeComponent();
}
private void Form3_Load(object sender, EventArgs e)
{
timer1.Enabled = true;
}
private void timer1_Tick(object sender, EventArgs e)
{
if (p1)
{
this.Opacity = this.Opacity + 0.05;
if (this.Opacity == 1)
{
p1 = false;
p2 = true;
}
}
else if (time < 1)
{
time += 0.1;
}
else if (p2)
{
this.Opacity = this.Opacity - 0.05;
if (this.Opacity == 0)
