具體實現方法如下：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39

namespace WindowsApplication1 { ??public partial class Form2 : Form ??{ ????public Form2() ????{ ??????InitializeComponent(); ??????this.Opacity = 1; ??????this.Text = "opacity=1"; ??????this.TopMost = true; ????} ????private void Form2_Activated(object sender, EventArgs e) ????{ ??????this.timer1.Enabled = true; ????} ????private void Form2_Deactivate(object sender, EventArgs e) ????{ ??????this.timer1.Enabled = false; ??????this.Opacity = 1; ??????this.Text = "opacity=" + this.Opacity.ToString(); ????} ????private void Form2_Load(object sender, EventArgs e) ????{ ????} ????private void timer1_Tick(object sender, EventArgs e) ????{ ??????if (this.Opacity > 0) ??????{ ????????this.Opacity -= 0.1; ????????this.Text = "opacity=" + this.Opacity.ToString(); ??????} ??????else if (this.Opacity == 0) ??????{ ????????this.Close(); ??????} ??????else this.timer1.Enabled = false; ????} ??} }
