C#實現托盤應用程式

下面是我根據網路上的應用程式改編的一個簡單的托盤程式的DEMO,實現了一般托盤程式的準系統

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

namespace WindowsApplication4
{
    public partial class Form1 : Form
    {

        private Icon mNetIcon = new Icon("appMain.ico");

        private NotifyIcon TrayIcon;

        private ContextMenu notifyiconMnu;

        public Form1()
        {
            InitializeComponent();
            Initializenotifyicon();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            this.MaximizeBox = false;
            this.MinimizeBox = false;
            this.WindowState = System.Windows.Forms.FormWindowState.Minimized;

        }

        private void Initializenotifyicon()
        {
            //設定托盤程式的各個屬性
            TrayIcon = new NotifyIcon();
            TrayIcon.Icon = mNetIcon;
            TrayIcon.Text = "用Visual C#做托盤程式";
            TrayIcon.Visible = true;
            TrayIcon.Click += new System.EventHandler(this.click);

            ////定義一個MenuItem數組，並把此數組同時賦值給ContextMenu對象
            MenuItem[] mnuItms = new MenuItem[1];
            mnuItms[0] = new MenuItem();
            mnuItms[0].Text = "退出系統";
            mnuItms[0].Click += new System.EventHandler(this.showmessage);

            notifyiconMnu = new ContextMenu(mnuItms);
            TrayIcon.ContextMenu = notifyiconMnu;
            ////為托盤程式加入設定好的ContextMenu對象
        }

        private void Form1_FormClosed(object sender, FormClosedEventArgs e)
        {
            TrayIcon.Visible = false;
        }
        public void click(object sender, System.EventArgs e)
        {
            MessageBox.Show("Visual C#編寫托盤程式中的事件響應");
        }

        public void showmessage(object sender, System.EventArgs e)
        {
            MessageBox.Show("你選擇了退出系統!");
            this.Close();
        }

    }
}
