界面比较简单，主要两个button 一个NotifyIcon 和 右键菜单 控件，
NotifyIcon 属性，如下：
并为NotifyIcon指定了DoubleClick事件：
主窗体增加两个事件：
整体代码如下：
using Pallet_Common;
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Configuration;
using System.Data;
using System.Diagnostics;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms; namespace Pallet_01
{
public partial class MainForm : Form
{ public MainForm()
{
InitializeComponent();
this.btnEnd.Enabled = false;
this.停止ToolStripMenuItem.Enabled = false;
} private void MainForm_Load(object sender, EventArgs e)
{
this.btnEnd.Enabled = false;
this.Resize += MainForm_Resize; } //单击窗体最小化时窗体隐藏
void MainForm_Resize(object sender, EventArgs e)
{
if (this.WindowState == FormWindowState.Minimized)
{
this.Hide();
}
} private void NotifyIcon_MouseDoubleClick(object sender, MouseEventArgs e)
{
this.Show(); // 窗体显现
this.WindowState = FormWindowState.Normal; //窗体回复正常大小
} private void btnStart_Click(object sender, EventArgs e)
{ Scheduler.StartUp();
this.btnStart.Enabled = false;
this.btnEnd.Enabled = true;
this.启动ToolStripMenuItem.Enabled = false;
this.停止ToolStripMenuItem.Enabled = true; string pageSize = ConfigurationManager.AppSettings["PageSize"];
this.lblCount.Text = pageSize + " 条"; this.lblCount.Update(); } private void btnEnd_Click(object sender, EventArgs e)
{ Scheduler.Stop();
this.btnStart.Enabled = true;
this.btnEnd.Enabled = false;
this.启动ToolStripMenuItem.Enabled = true;
this.停止ToolStripMenuItem.Enabled = false; this.lblCount.Text = "----";
this.lblCount.Update();
} private void MainForm_FormClosing(object sender, FormClosingEventArgs e)
{
if (MessageBox.Show("是否确认退出程序？", "退出", MessageBoxButtons.OKCancel, MessageBoxIcon.Question) == DialogResult.OK)
{
//关闭所有的线程，释放占用内存
this.Dispose();
this.Close();
}
else
{
e.Cancel = true;
}
} #region 右键菜单事件
private void 启动ToolStripMenuItem_Click(object sender, EventArgs e)
{
Scheduler.StartUp();
this.btnStart.Enabled = false;
this.btnEnd.Enabled = true;
this.启动ToolStripMenuItem.Enabled = false;
this.停止ToolStripMenuItem.Enabled = true;
} private void 停止ToolStripMenuItem_Click(object sender, EventArgs e)
{
Scheduler.Stop();
this.btnStart.Enabled = true;
this.btnEnd.Enabled = false;
this.启动ToolStripMenuItem.Enabled = true;
this.停止ToolStripMenuItem.Enabled = false;
} private void 退出ToolStripMenuItem_Click(object sender, EventArgs e)
{
if (MessageBox.Show("是否确认退出程序？", "退出", MessageBoxButtons.OKCancel, MessageBoxIcon.Question) == DialogResult.OK)
{
// 关闭所有的线程，释放占用内存
this.Dispose();
this.Close();
}
}
#endregion
}
}
其中打开一个程序后，不允许再次打开，也就是运行后，只能运行一个，如下：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading;
using System.Threading.Tasks;
using System.Windows.Forms; namespace Pallet_01
{
static class Program
{
/// <summary>
/// 应用程序的主入口点。
/// </summary>
[STAThread]
static void Main()
{
bool bCreateNew;
Mutex m = new Mutex(false, "Pallent_01", out bCreateNew);
if (bCreateNew)
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new MainForm());
}
}
}
}
