快速入门

我们在主页上有不少例子,这是让您入门的第一个:

常规格式:分 时 天 月 周

var crontab = Crontab.Parse("* * * * *");
var nextOccurrence = crontab.GetNextOccurrence(DateTime.Now);

支持年份:分 时 天 月 周 年

var crontab = Crontab.Parse("* * * * * *", CronStringFormat.WithYears);
var nextOccurrence = crontab.GetNextOccurrence(DateTime.Now);

支持秒数:秒 分 时 天 月 周

var crontab = Crontab.Parse("* * * * * *", CronStringFormat.WithSeconds);
var nextOccurrence = crontab.GetNextOccurrence(DateTime.Now);

支持秒和年:秒 分 时 天 月 周 年

var crontab = Crontab.Parse("* * * * * * *", CronStringFormat.WithSecondsAndYears);
var nextOccurrence = crontab.GetNextOccurrence(DateTime.Now);

获取休眠差实现简单定时任务

// 阻塞方式
var crontab = Crontab.Parse("* * * * * *", CronStringFormat.WithSeconds);
while(true)
{
    Thread.Sleep(crontab.GetSleepMilliseconds(DateTime.Now));
    Console.WriteLine(DateTime.Now.ToString("G"));
}

// 无阻塞方式
var crontab = Crontab.Parse("* * * * * *", CronStringFormat.WithSeconds);
Task.Factory.StartNew(async () =>
{
    while (true)
    {
        await Task.Delay(crontab.GetSleepMilliseconds(DateTime.Now));
        Console.WriteLine(DateTime.Now.ToString("G"));
    }
}, TaskCreationOptions.LongRunning);

BackgroundService 实现简单定时任务

using TimeCrontab;

namespace WorkerService;

public class Worker : BackgroundService
{
    private readonly ILogger<Worker> _logger;

    private readonly Crontab _crontab;

    public Worker(ILogger<Worker> logger)
    {
        _logger = logger;
        _crontab = Crontab.Parse("* * * * * *", CronStringFormat.WithSeconds);
    }

    protected override async Task ExecuteAsync(CancellationToken stoppingToken)
    {
        while (!stoppingToken.IsCancellationRequested)
        {
            var taskFactory = new TaskFactory(System.Threading.Tasks.TaskScheduler.Current);

            await taskFactory.StartNew(async () =>
            {
                // 你的业务代码写到这里面

                _logger.LogInformation("Worker running at: {time}", DateTime.Now);

                await Task.CompletedTask;
            }, stoppingToken);

            await Task.Delay(_crontab.GetSleepMilliseconds(DateTime.Now), stoppingToken);
        }
    }
}
