winform最小化后隐藏到右下角，单击或双击后恢复
我知道这个方法怎么写，我不知道什么时候执行。。（非MainForm_SizeChanged）

C# code

        private void normalForm()//恢复        {            this.Visible = true;            this.WindowState=FormWindowState.Normal;        }        private void minForm()//隐藏           {               WindowState = FormWindowState.Minimized;               this.Visible = false;               this.notifyIcon1.Visible = true;            }

C# code

private void Form1_SizeChanged(object sender, EventArgs e)        {            if (this.WindowState == FormWindowState.Minimized)            {                                this.Visible = false;//隐藏窗体                this.notifyIcon1.Visible = true;//显示托盘图标                this.notifyIcon1.Text = this.Text;//设置托盘文本                            }                   }
