利用c#制作托盘程序，并禁止多个应用实例运行
转载自：https://www.cnblogs.com/yjmyzz/articles/1021058.html
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
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()); } } }}
