Make Clock UWP (C#)

I'm writing application for windows 10 and need to display Time inside the UI.

I made the display like this

 Time.Text = DateTime.Now.ToString("h:mm:ss tt");

But I need to update it, any advice on how I can do this?

Try this inside your XAML:

    <TextBlock x:Name="Time" HorizontalAlignment="Center" VerticalAlignment="Center"></TextBlock>

and this as your code:

public sealed partial class ClockPage : Page
{
    DispatcherTimer Timer = new DispatcherTimer();

    public ClockPage()
    {
        InitializeComponent();
        DataContext = this;
        Timer.Tick += Timer_Tick;
        Timer.Interval = new TimeSpan(0, 0, 1);
        Timer.Start();
    }

    private void Timer_Tick(object sender, object e)
    {
        Time.Text = DateTime.Now.ToString("h:mm:ss tt");
    }
}

Obviously you'll need to change the name of the class to match what you've got, but you get the idea. You may want to tidy things up by using MVVM, this is just a bare-bones example.

You can simply add a Timer to your class:

private Timer timer;

Create a handler for the Elapsed event of the timer:

private void timer_Elapsed(object sender, ElapsedEventArgs e)
{
    Time.Text = DateTime.Now.ToString("h:mm:ss tt");
}

And then in the constructor of your window, you can add this:

timer = new Timer(1000); // let the timer tick every 1000 ms = every second
timer.Elapsed += new ElapsedEventHandler(timer_Elapsed);
timer.Enabled = true; // Enable it
