C#把winForm应用最小化右下角任务栏

一.把NotifyIcon控件拉到form窗体上

二.设置icon图标,不然不会出现在右下角任务栏

三 .设置icon点击事件

private void showTaskBar_MouseDown(object sender, MouseEventArgs e)
        {
            if (e.Button == MouseButtons.Left)//判断鼠标的按键
            {
                //点击时判断form是否显示,显示就隐藏,隐藏就显示
                if (this.WindowState == FormWindowState.Normal)
                {
                    this.WindowState = FormWindowState.Minimized;
                    this.Hide();
                }
                else if (this.WindowState == FormWindowState.Minimized)
                {
                    this.Show();
                    this.WindowState = FormWindowState.Normal;
                    this.Activate();
                }
            }
            else if (e.Button == MouseButtons.Right)
            {
                //右键退出事件
                if (MessageBox.Show("是否需要关闭程序？", "提示:", MessageBoxButtons.OKCancel, MessageBoxIcon.Exclamation) == DialogResult.OK)//出错提示
                {
                    //关闭窗口
                    DialogResult = DialogResult.No;
                    Dispose();
                    Close();
                }
            }
        }
