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


}

3.放一个上下文菜单，添加几个基本项,"显示主窗体","退出" ,将这个菜单挂到NotifyIcon上

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

using System;
using System.Collections.Generic;
using System.Windows.Forms;
using System.Threading;

namespace LuceneTest
{
static
class Program
{
/**////
<summary>
/// 应用程序的主入口点。
///
</summary>
[STAThread]
static
void Main()
{
bool bCreatedNew;
Mutex m
= new Mutex(false,
"Product_Index_Cntvs",
out bCreatedNew);
if (bCreatedNew)
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new Form1());
}
}
}
}
