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。

{
bool bCreatedNew;
Mutex m = new Mutex(false, "Product_Index_Cntvs", out bCreatedNew);
if (bCreatedNew)

{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new Form1());
}
}
}
}
