Team , We are using windows form c#. Is there any library for auto refresh (need to few logic every 1 min. Please see the attachment ) . ? These setting is within the app. Thanks Shiv

this should suffice.

var timer = new PeriodicTimer(TimeSpan.FromSeconds(10));

while (await timer.WaitForNextTickAsync())
{
    Console.WriteLine("Hello World after 10 seconds")
}

var timer = new PeriodicTimer(TimeSpan.FromSeconds(10));

while (await timer.WaitForNextTickAsync())
{
    Console.WriteLine("Hello World after 10 seconds")
}

Also this aint outlook bro 🤣

No timer.Dispose() is not working. It keeps on triggering every 10 secs @Dharmang

private async void checkBox2_CheckedChanged(object sender, EventArgs e) { var timer = new PeriodicTimer(TimeSpan.FromSeconds(10)); if (checkBox2.Checked == true) { while (await timer.WaitForNextTickAsync()) { MessageBox.Show("Triggered"); } } else { timer.Dispose();
} } it is inside checkbox checked event inside windows form

can you also share the xaml code

public PeriodicTimer timer = new PeriodicTimer(TimeSpan.FromSeconds(3));

private async void CheckBox_Checked(object sender, RoutedEventArgs e)
{
    while (await timer.WaitForNextTickAsync())
    {
        Debug.WriteLine("triggered");
    }
}

private void CheckBox_Unchecked(object sender, RoutedEventArgs e)
{
    timer.Dispose();
}

public PeriodicTimer timer = new PeriodicTimer(TimeSpan.FromSeconds(3));

private async void CheckBox_Checked(object sender, RoutedEventArgs e)
{
    while (await timer.WaitForNextTickAsync())
    {
        Debug.WriteLine("triggered");
    }
}

private void CheckBox_Unchecked(object sender, RoutedEventArgs e)
{
    timer.Dispose();
}

this is winui3 code but similar

OK let me try this public PeriodicTimer timer = new PeriodicTimer(TimeSpan.FromSeconds(3)); Should this code go inside constructer? We need to trigger it somewhere right? timer.Dispose(); worked if I move this outside the checkbox changed event public PeriodicTimer timer = new PeriodicTimer(TimeSpan.FromSeconds(3));
but again it wont start if i enable it . public partial class Form1 : Form { PeriodicTimer timer; public Form1() { InitializeComponent(); } private async void checkBox1_CheckedChanged(object sender, EventArgs e) { if (checkBox1.Checked == true) { timer = new PeriodicTimer(TimeSpan.FromSeconds(5)); while (await timer.WaitForNextTickAsync()) { MessageBox.Show("Triggered"); } } else { timer.Dispose(); } } } this worked ... there is no CheckBox_Unchecked in windows form so i am checking inside the main check changed event

ya this would work maybe dispose absolutely clears the initiated object
