问题
Currently I need to implement a simple non-blocking delay function in a Windows Store app project. This function should do nothing, just idle for a specific period of time without blocking the UI. My question is: how to implement such a function properly? I know this is an old question, but I really have no clue after some search online.
Best wishes!
[Edit] I've tried this but not work.
public static async Task WaitFor(int millisecondsDelay)
{
var idleTask = Task.Run(() => { Task.Delay(millisecondsDelay); });
await Task.WhenAny(new Task[] { idleTask });
}
回答1:
See Task.Delay
It schedules a task that completes at a future time using timer rather than blocking a thread.
An example that waits 5 seconds and then continues:
private async Task DelayThenDoSomeWork()
{
await Task.Delay(5000);
// Do something
var dialog = new MessageDialog("Waiting completed.");
await dialog.ShowAsync();
}
