Wpf程序最小化后，无法重新激活

Question

Wpf程序最小化后，放置一段时间不用，等到平板熄屏后，重新点亮屏幕，却无法重新激活程序，让程序弹出

请教下这个是什么原因造成的。

谢谢<tbdiv id="playerControlBtn"></tbdiv><tbdiv id="leftFullStackButton"></tbdiv><tbdiv id="rightFullStackButton"></tbdiv>

Hi touhou_fantasy,

从你的描述，不太清楚是什么原因。 我建议你可以尝试使用 NotifyIcon 来实现程序最小化和显示。 你可以参考下面简单的代码。

      WindowState ws;
        WindowState wsl;
        NotifyIcon notifyIcon;
        public WPFwindowsshowhide()
        {
            InitializeComponent();
            icon();
            wsl = WindowState;
        }

        private void icon()
        {
            this.notifyIcon = new NotifyIcon();
            this.notifyIcon.BalloonTipText = "你好，程序开启";
            this.notifyIcon.Text = "程序--运行中";
            this.notifyIcon.Icon = new System.Drawing.Icon("favicon.ico");
            this.notifyIcon.Visible = true;
            notifyIcon.MouseDoubleClick += OnNotifyIconDoubleClick;
            this.notifyIcon.ShowBalloonTip(500);
        }

        private void OnNotifyIconDoubleClick(object sender, EventArgs e)
        {
            this.Show();
            WindowState = wsl;
        }

        private void Window_StateChanged(object sender, EventArgs e)
        {
            ws = WindowState;
            if (ws == WindowState.Minimized)
            {
                this.Hide();
            }
        }

Best Regards,
