C#關閉以后窗體最小化，雙擊以后窗體正常顯示

 

此時需要增加C#控件（notifyIcon），為notifyIcon1增加圖標

 

private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
e.Cancel = true;//取消窗體的關閉事件
this.WindowState = FormWindowState.Minimized;//使當前窗體最小化
notifyIcon1.Visible = true;//使最下滑的圖標可見
}

 

//增加notifyIcon的雙擊事件

private void notifyIcon1_MouseDoubleClick(object sender, MouseEventArgs e)
{
if (this.WindowState == FormWindowState.Minimized) //判斷當前窗體的狀態是否為最小化
{
this.WindowState = FormWindowState.Normal;//將當前窗體狀態恢復為正常
notifyIcon1.Visible = false;//將notifyIcon圖標隱藏
}
}
