C#怎样才能实现窗体最小化到托盘呢？

VS2005 中工具栏里有一个 NotifyIcon控件，双击此控件，加上下面两段代码，即可轻松实现窗体最小化到托盘了。
private void Form1_Resize(object sender, System.EventArgs e) {
if (this.WindowState == FormWindowState.Minimized) {
this.Visible = false;
this.notifyIcon1.Visible = true;
}
}
private void notifyIcon1_Click(object sender, System.EventArgs e) {
this.Visible = true;
this.WindowState = FormWindowState.Normal;
this.notifyIcon1.Visible = false;
}
然后自己再加一张ico的图片
