我正在尝试找到一个简单的Quartz.Net示例,当单击一个按钮时,它会启动Quartz.Net功能。
我能够使用Quartz.Net示例(控制台应用程序)并更改一些内容来生成它(SimpleExample.cs):
public virtual void Run()
{
ISchedulerFactory sf = new StdSchedulerFactory();
IScheduler sched = sf.GetScheduler();
DateTimeOffset runTime = DateBuilder.EvenMinuteDate(DateTime.UtcNow);
DateTimeOffset startTime = DateBuilder.NextGivenSecondDate(null, 10);
IJobDetail job = JobBuilder.Create<HelloJob>()
.WithIdentity("job1", "group1")
.Build();
ITrigger trigger = TriggerBuilder.Create()
.WithIdentity("trigger1", "group1")
.StartAt(runTime)
.WithCronSchedule("5 0/1 * * * ?")
.Build();
sched.ScheduleJob(job, trigger);
sched.Start();
}
但是我对如何通过按钮点击触发这一点感到困惑。我以为我可以这样做:
private void button1_Click(object sender, EventArgs e)
{
code here....
}
但那没用。
我查看了以下网站,但并非所有网站都通过点击按钮启动此功能。
http://www.mkyong.com/java/quartz-scheduler-example/ - Java,我很难理解其中的差异(我对这一切都很陌生!)。
http://www.hardcodet.net/2010/01/lightweight-task-slash-job-scheduling-with-silverlight-support - 这很有帮助,但我不清楚Silverlight如何使用常规的.Net表单。看起来像一个完全不同的项目。

我查看了建议的代码,并在另一个(简单)示例中找到了以下链接。 http://simplequartzschedulerincsharp.blogspot.com/
我继续构建了一个简单的表单,对作者的代码进行了一些更改,如下所示:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using Quartz;
using Quartz.Impl;
//http://simplequartzschedulerincsharp.blogspot.com/
namespace QuartzExampleWF
{
public partial class Form1 : Form
{
private static IScheduler _scheduler;
public Form1()
{
InitializeComponent();
ISchedulerFactory schedulerFactory = new StdSchedulerFactory();
_scheduler = schedulerFactory.GetScheduler();
AddJob();
}
public static void AddJob()
{
IMyJob myJob = new MyJob();
JobDetail jobDetail = new JobDetail("Job1", "Group1", myJob.GetType());
CronTrigger trigger = new CronTrigger("Trigger1", "Group1", "5 0/1 * * * ?");
_scheduler.ScheduleJob(jobDetail, trigger);
DateTime? nextFireTime = trigger.GetNextFireTimeUtc();
}
private void button1_Click(object sender, EventArgs e)
{
_scheduler.Start();
}
internal class MyJob : IMyJob
{
public void Execute(JobExecutionContext context)
{
DateTime now = DateTime.Now;
DoMoreWork();
}
public void DoMoreWork()
{
//more code...
}
}
internal interface IMyJob : IJob
{
}
}
}
我之前从未做过内部课程,并且遇到了引用文本框的问题。例如,我正在尝试执行以下操作:
public void Execute(JobExecutionContext context)
{
DateTime now = DateTime.Now;
this.textbox1 = Now.value;
DoMoreWork();
}
但我无法引用文本框。我对datagrid或toolStripStatusLabel有同样的问题。在上述代码下访问文本框或toolStripStatusLabel等对象的最佳方法是什么?
答案 0 :(得分:13)
你可以这样做:
public partial class MainForm : Form
{
IScheduler sched;
IJobDetail job;
public MainForm()
{
InitializeComponent();
ISchedulerFactory sf = new StdSchedulerFactory();
IScheduler sched = sf.GetScheduler();
DateTimeOffset runTime = DateBuilder.EvenMinuteDate(DateTime.UtcNow);
DateTimeOffset startTime = DateBuilder.NextGivenSecondDate(null, 10);
job = JobBuilder.Create<HelloJob>()
.WithIdentity("job1", "group1")
.Build();
ITrigger trigger = TriggerBuilder.Create()
.WithIdentity("trigger1", "group1")
.StartAt(runTime)
.WithCronSchedule("5 0/1 * * * ?")
.Build();
sched.ScheduleJob(job, trigger);
}
private void startScheduler_Click(object sender, EventArgs e)
{
sched.Start();
}
private void startJob_Click(object sender, EventArgs e)
{
sched.TriggerJob(job.Name, job.Group);
}
}
我不清楚你是否想要按钮启动调度程序或启动作业,所以我为两者添加了一个按钮。关键是您要单独初始化调度程序,而不是单击按钮启动调度程序。初始化它的最简单的地方是在表单的构造函数中。
