I want to implement a countdown timer that use to work on CMD into a textblock with wpf.
I can't figure it out how to implement that code into a textblock.
DateTime daysLeft1 = DateTime.Parse("1/02/2022 12:00:01 AM");
DateTime startDate1 = DateTime.Now;
TimeSpan t = daysLeft1 - startDate1;
string countDown = string.Format("{0} Days, {1} Hours, {2} Minutes, {3} Seconds until launch.",
t.Days, t.Hours, t.Minutes, t.Seconds);
Thank you for your help ! .
EDIT: The code Below seem to work but I have error CS0120
"An object reference is required for the non-static field, method, or property 'TextBlock.Text' "
public partial class justdancetrailer : Window
{
private readonly DispatcherTimer Timer = new DispatcherTimer();
private readonly DateTime daysLeft;
public justdancetrailer()
{
InitializeComponent();
daysLeft = DateTime.Parse("1/02/2022 12:00:00 AM");
Timer.Interval = TimeSpan.FromSeconds(1.0); ;
Timer.Tick = Timer_Tick;
Timer.Start();
}
private void Timer_Tick(object sender, EventArgs e)
{
TimeSpan t = daysLeft.Subtract(DateTime.Now);
if (t.Seconds >= 0)
{
string countDown = string.Format("{0} Days, {1} Hours, {2} Minutes, {3} Seconds until launch.",
t.Days, t.Hours, t.Minutes, t.Seconds);
TextBlock.Text = countDown;
daysLeft.AddSeconds(-1);
}
else
{
Timer.Stop();
}
}
private void trailer_play(object sender, RoutedEventArgs e)
{
trailer.Play();
}
private void trailer_stop(object sender, RoutedEventArgs e)
{
trailer.Stop();
trailer.Close();
}
private void trailer_pause(object sender, RoutedEventArgs e)
{
trailer.Pause();
}
private void ValueChanged(object sender, RoutedPropertyChangedEventArgs<double> e)
{
trailer.Volume = e.NewValue;
}
}
}
And this is the TextBlock :
<TextBlock x:Name="countDown" HorizontalAlignment="Left" Margin="40,100,0,0" TextWrapping="Wrap" VerticalAlignment="Top"
Grid.ColumnSpan="2" Width="250" Height="58" Foreground="White"
Grid.Column="3" Grid.Row="1"
Text=""/>
CodePudding user response:
Supposing you need an interval equals 1 second.
private readonly DispatcherTimer Timer = new DispatcherTimer();
private readonly DateTime daysLeft;
public MainWindow()
{
InitializeComponent();
daysLeft = DateTime.Parse("1/02/2022 12:00:00 AM");
Timer.Interval = TimeSpan.FromSeconds(1.0); ;
Timer.Tick = Timer_Tick;
Timer.Start();
}
private void Timer_Tick(object sender, EventArgs e)
{
TimeSpan t = daysLeft.Subtract(DateTime.Now);
if (t.Seconds >= 0)
{
string countDown = string.Format("{0} Days, {1} Hours, {2} Minutes, {3} Seconds until launch.",
t.Days, t.Hours, t.Minutes, t.Seconds);
textBlock.Text = countDown;
daysLeft.AddSeconds(-1);
}
else
{
Timer.Stop();
}
}
