c# – 如何使用线程或定时器从WPF客户端应用程序定期执行方法[已

// The `onTick` method will be called periodically unless cancelled.
private static async Task RunPeriodicAsync(Action onTick,TimeSpan dueTime,TimeSpan interval,CancellationToken token)
{
  // Initial wait time before we begin the periodic loop.
  if(dueTime > TimeSpan.Zero)
    await Task.Delay(dueTime,token);

  // Repeat this loop until cancelled.
  while(!token.IsCancellationRequested)
  {
    // Call our onTick function.
    onTick?.Invoke();

    // Wait to repeat again.
    if(interval > TimeSpan.Zero)
      await Task.Delay(interval,token);       
  }
}

那么你可以在某处调用这个方法：

private void Initialize()
{
  var dueTime = TimeSpan.FromSeconds(5);
  var interval = TimeSpan.FromSeconds(5);

  // TODO: Add a CancellationTokenSource and supply the token here instead of None.
  RunPeriodicAsync(OnTick,dueTime,interval,CancellationToken.None);
}

private void OnTick()
{
  // TODO: Your code here
}
