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);
}
}
}
