这是在.net core worker上的特定时间（小时，分钟和秒）启动方法的最佳方法

示例：我在19/05/2020上午6.00开始比赛一次，我使用以下方法，这种方法会延迟两秒钟：

 protected async override Task ExecuteAsync(CancellationToken stoppingToken)
        {
            while (!stoppingToken.IsCancellationRequested)
            {
                await CheckCompetitionStarted();
                await Task.Delay(5, stoppingToken);
            }
        }

 private async Task CheckCompetitionStarted()
        {
            try
            {
                var CurrentComp = _game.GetCurrentCompetition();

                if (CurrentComp != null)
                {
                    if (CurrentComp.PlandStartingTime.Date == DateTime.UtcNow.Date
                        && CurrentComp.PlandStartingTime.Hour == DateTime.UtcNow.Hour
                        && CurrentComp.PlandStartingTime.Minute == DateTime.UtcNow.Minute)
                    {
                        _logger.LogInformation($"Start Competition :{DateTime.Now} ");

                      await  CurrentComp.Start();

                        CurrentComp.Close();
                    }
                }

            }
            catch (Exception ex)
            {
                _logger.LogError(ex,"");
            }
        }

这样的事情如何：

    public async Task RunAtTime(DateTime targetTime, Action action)
    {
        var remaining = targetTime - DateTime.Now ;
        if (remaining < TimeSpan.Zero)
        {
            throw new ArgumentException();
        }

        await Task.Delay(remaining);
        action();
    }

如果要返回值，请用Task和Action替换Task<T>和Func<T>。

如果要调用异步方法，请用Action（或Func<Task>）替换Func<Task<T>>。
