  实现托盘(任务栏图标与托盘图标互斥),并且在点击任务栏图标时实现的最小化与点击最小化按钮分离。

具体如下:

1、向窗体上添加如下控件:MenuStrip menuStrip1, NotifyIcon ni_frmMain,Timer timer1, ContentMenuStrip cms_notify。其中notify中包含显示、退出等。

2、实现的代码:

//字段:
     //当前子Form
        private CurrentForm childForm = null;

        //上次窗体的状态
        private FormWindowState lastFormState;

        //是否点击的是最小化按钮
        private bool isMinBoxHited;

//构造函数内
    this.ni_frmMain.Visible = false;


        #region 托盘相关代码

        #region 私有方法 处理窗体的 显示 隐藏 关闭(退出)

        /// <summary>
        /// 显示
        /// </summary>
        private void ShowMainForm()
        {
            this.Show();
            this.WindowState = this.lastFormState;
            this.Activate();

            this.ShowInTaskbar = true;  //任务栏中显示窗体图标
            this.ni_frmMain.Visible = false;//图盘中隐藏图标
        }

        /// <summary>
        /// 隐藏
        /// </summary>
        private void HideMainForm()
        {
            this.Hide();

            this.ShowInTaskbar = false;  //任务栏中显示窗体图标
            this.ni_frmMain.Visible = true;//图盘中隐藏图标
        }

        /// <summary>
        /// 关闭(退出)
        /// </summary>
        private void ExitMainForm()
        {
            if (MessageBox.Show("您确定要退出主程序吗?", "确认退出", MessageBoxButtons.OKCancel, MessageBoxIcon.Question, MessageBoxDefaultButton.Button2) == DialogResult.OK)
            {
                this.ni_frmMain.Visible = false;
                this.Close();
                this.Dispose();
                Application.Exit();
            }
        }
