托盘程序的制作:
1.把NotifyIcon控件拉一个到窗体上，并设置NotifyIcon的Icon(很重要!否则运行后看不到效果)
2.窗体关闭时，将程序最小化到系统托盘上
private
void
Form1_FormClosing(
object
sender, FormClosingEventArgs e)
{
//MessageBox.Show("程序将最小化到系统托盘区"); e.Cancel = true; // 取消关闭窗体 this.Hide();this.ShowInTaskbar = false;//取消窗体在任务栏的显示 this.notifyIcon1.Visible = true;//显示托盘图标 
}
private
void
menuShow_Click(
object
sender, EventArgs e)
{this.Show();this.ShowInTaskbar = true;this.notifyIcon1.Visible = false;}
private
void
menuExit_Click(
object
sender, EventArgs e)
{this.Dispose(true); Application.ExitThread();}
4.左键单击托盘图标时，显示主窗体,右击时当然是弹出上面设置的菜单
private
void
notifyIcon1_MouseClick(
object
sender, MouseEventArgs e)
{if (e.Button == MouseButtons.Left)
{this.Show();this.ShowInTaskbar = true;this.notifyIcon1.Visible = false;
}}
防止这个程序同时运行多个
