任务栏windows7中的c＃通知

Question

我想在c＃winforms中编写一个简单的程序，它在一个固定的时间内（例如在13:00和21:00）显示给用户（在任务栏窗口7或10中）的通知。

我怎样才能做到这一点？

Answer 1

基本上，如果DateTime.Now （当前小时）等于特定小时，则显示通知图标。

您应该在计时器/任务中运行此代码。

if (DateTime.Now.Hour == 13 && DateTime.Now.Minute == 00 || DateTime.Now.Hour == 21 && DateTime.Now.Minute == 00)
{
    var notification = new System.Windows.Forms.NotifyIcon()
    {
        Visible = true,
        Icon = System.Drawing.SystemIcons.Information,
        BalloonTipText = "This is my notify icon",
    };
    notification.ShowBalloonTip(1000);
}

Answer 2

这应该做到......

Timer timer = new Timer();
    public Form1()
    {
        InitializeComponent();

        timer.Tick += Timer_Tick;
        timer.Interval = 1000;
        timer.Start();

    }
    int lastNotify = 0;
    private void Timer_Tick(object sender, EventArgs e)
    {
        if ((DateTime.Now.Hour == 16 && lastNotify != 16) || (DateTime.Now.Hour == 21 && lastNotify != 21))
        {
            this.notifyIcon1.BalloonTipText = "Whatever";
            this.notifyIcon1.BalloonTipTitle = "Title";
            this.notifyIcon1.Visible = true;
            this.notifyIcon1.ShowBalloonTip(3);

            lastNotify = DateTime.Now.Hour;
        }
    }
