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();

        }
