Winform设置托盘程序，托盘显示

1.拖一个NotifyIcon，一个ContextMenuStrip控件到主窗体中

2、设置notifyIcon1，一个contextMenuStrip1（如下图）

Icon为托盘图标，Text托盘显示文字，ContextMenuStrip右键菜单（退出），设置退出单击事件

3、添加主窗体关闭事件（FormClosing）

4、事件代码

        private void MyService_FormClosing(object sender, FormClosingEventArgs e)
        {
            // 注意判断关闭事件reason来源于窗体按钮，否则用菜单退出时无法退出!
            if (e.CloseReason == CloseReason.UserClosing)
            {
                //取消"关闭窗口"事件
                e.Cancel = true;
                //使关闭时窗口向右下角缩小的效果
                this.WindowState = FormWindowState.Minimized;   
                this.notifyIcon1.Visible = true;
                this.Hide();
                return;
            }
        }

        private void notifyIcon1_MouseDoubleClick(object sender, MouseEventArgs e)
        {
            if (this.Visible)
            {
                this.WindowState = FormWindowState.Minimized;
                this.notifyIcon1.Visible = true;
                this.Hide();
            }
            else
            {
                this.Visible = true;
                this.WindowState = FormWindowState.Normal;                
                this.Activate();
            }
        }

        private void MenuItemTuichu_Click(object sender, EventArgs e)
        {
            this.notifyIcon1.Visible = false;
            this.Close();
            this.Dispose();
            System.Environment.Exit(0);
        }
