wpf 窗体中显示当前系统时间

先看一下效果:

 

 

 

这其实是我放置了两个TextBlock,上面显示当前的日期,下面显示时间。

接下来展示一下代码:

在XAML中:

<StackPanel Width="205"
                    Margin="0,0,57,0"
                    HorizontalAlignment="Right">
            <TextBlock Height="Auto"
                       Margin="10,5,0,0"
                       Name="tbDateText"
                       Foreground="White"
                       FontWeight="Bold"
                       FontFamily="Arial"
                       FontSize="15" />
            <TextBlock Height="Auto"
                       Margin="10,5,0,0"
                       Name="tbTimeText"
                       Foreground="#ffa51f"
                       FontWeight="Bold"
                       FontFamily="Calibri"
                       FontSize="23" />
        </StackPanel>

 

在主窗体的cs中代码为:

/// <summary>  

/// 定义一个定时器

/// </summary>

 private DispatcherTimer ShowTimer;

 public MainWindow()  

{  

           InitializeComponent();

            ShowTime();    //在这里窗体加载的时候不执行文本框赋值,窗体上不会及时的把时间显示出来,而是等待了片刻才显示了出来

            ShowTimer = new System.Windows.Threading.DispatcherTimer();

            ShowTimer.Tick += new EventHandler(ShowCurTimer);//起个Timer一直获取当前时间

            ShowTimer.Interval = new TimeSpan(0, 0, 0, 1, 0);

            ShowTimer.Start();     

 }     

public void ShowCurTimer(object sender, EventArgs e)

{      

       ShowTime();

 }

//ShowTime方法

private void ShowTime()
{
            //获得年月日
            this.tbDateText.Text = DateTime.Now.ToString("yyyy/MM/dd");   //yyyy/MM/dd
            //获得时分秒
            this.tbTimeText.Text = DateTime.Now.ToString("HH:mm:ss");
}
