C#- Winform最小化到托盘

实现前先拉一个notifyIcon控件，在Icon属性中加入一个ICON小图标，然后具体的代码实现如下：

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

namespace NotifyDemo
{
    public partial class Form1 : Form
    {
        private ContextMenu notifyiconMnu;

        public Form1()
        {
            
            InitializeComponent();
        }

        //通知区域的菜单
        public void Initializenotifyicon()
        {
            //定义一个MenuItem数组，并把此数组同时赋值给ContextMenu对象 
            MenuItem[] mnuItms = new MenuItem[3];
            mnuItms[0] = new MenuItem();
            mnuItms[0].Text = "显示窗口";
            mnuItms[0].Click += new System.EventHandler(this.notifyIcon1_funone);

            mnuItms[1] = new MenuItem("-");

            mnuItms[2] = new MenuItem();
            mnuItms[2].Text = "退出系统";
            mnuItms[2].Click += new System.EventHandler(this.notifyIcon1_funtwo);
            mnuItms[2].DefaultItem = true;

            notifyiconMnu = new ContextMenu(mnuItms);
            notifyIcon1.ContextMenu = notifyiconMnu;
        }

        //调用函数1
        public void notifyIcon1_funone(object sender, System.EventArgs e)
        {
            MessageBox.Show("funOne");
        }

        //调用函数2
        public void notifyIcon1_funtwo(object sender, System.EventArgs e)
        {
            MessageBox.Show("funTwo");
        }

        private void Form1_SizeChanged(object sender, EventArgs e)
        {
            if (this.WindowState == FormWindowState.Minimized) //判断是否最小化
            {
                this.notifyIcon1.Visible = true;//在通知区域显示
                this.Hide();//窗体隐藏
                this.ShowInTaskbar = false;//不显示在任务栏

                Initializenotifyicon();
            }

        }


        private void notifyIcon1_MouseClick(object sender, MouseEventArgs e)
        {
        //    if (e.Button == System.Windows.Forms.MouseButtons.Right)
        //    {
        //        this.Show();//窗体显示
        //        this.ShowInTaskbar = true;//在任务栏显示
        //        this.WindowState = FormWindowState.Normal;
        //        this.notifyIcon1.Visible = false;//在通知区域隐藏
        //    }
        }
    }
}
