Question

我要展示一个数字钟。这里,我不得不在24小时格式的正文中显示时间,我知道如何转换到12小时。

DispatcherTimer timerdigital;

    public MainWindow()
    {
        this.InitializeComponent();
        //StartTimer(null, null);

        timerdigital = new DispatcherTimer();
        timerdigital.Interval = TimeSpan.FromSeconds(1.0);
        timerdigital.Start();
        timerdigital.Tick += new EventHandler(delegate(object s, EventArgs a)
        {
            tbDigital.Text = "" + DateTime.Now.Hour + ":"
          + DateTime.Now.Minute + ":"
          + DateTime.Now.Second;


        });

感谢

不知道数字式显示,但为了从24小时转换为12小时24小时,最容易的方法是使用日记格式:

timerdigital.Tick += new EventHandler(delegate(object s, EventArgs a)
        {
            tbDigital.Text = DateTime.Now.ToString("hh:mm:ss tt");
        });

<代码>h为12小时格式的小时数,<>mm/code>为分钟,s为秒钟,<>>为。

Here is a nice ready to use source code for wpf:

About the 12/24 hour format:

 int smallhour = (Hour > 12) ? Hour - 12 : Hour;
