在winform程序里实现最小化隐藏到windows右下角

先放notifyIcon和contextmenustrip控件，并设置对于关系

然后

1.关闭事件里，阻止之间关闭按钮（为了使得用户单机右下角的退出时，能够退出，所以必须使用CloseReason属性）
  private void Form1_FormClosing(object sender, FormClosingEventArgs e)
        {

            if (e.CloseReason == CloseReason.ApplicationExitCall)
            {
                Application.Exit();
            }
            else
            {
                e.Cancel = true;
                this.WindowState = FormWindowState.Minimized;
                this.Hide();
                this.notifyIcon1.Visible = true;
            }

           
        }

2.双击icon还原
  private void notifyIcon1_MouseDoubleClick(object sender, MouseEventArgs e)
        {
           
              notifyIcon1.Visible = true;
              this.Show();
              this.Activate();
              this.WindowState = FormWindowState.Normal;
        }

3.右下角单机退出时，运行退出
        private void Exit_Click(object sender, EventArgs e)
        { 
            Application.Exit();
        }
