C# 定时任务 - XL、 - 博客园 (cnblogs.com)
工作中需要做个每天定时发邮件的功能，了解之后知道java里有做定时任务比较容易的方法，就是Quartz，在C#里叫Quartz.Net。
在写代码之前需要引用几个dll文件，分别是C5.dll、Common.Logging.dll和Quartz.dll；还有一个QuartzManager.cs文件，直接复制到项目中
QuartzManager.cs

窗体界面上只有一个Button按钮，点击之后将当前Windows窗体关闭，而我的定时任务就是实现这个关闭。
.closeForm（）；关闭窗体方法在另写的一个stopjob.cs类文件调用 这个类需要继承IJob
using Quartz; using System; using System.Collections.Generic; using System.Linq; using System.Text;namespace winform状态栏
{
[PersistJobDataAfterExecution]
[DisallowConcurrentExecution]
public class stopjob : IJob
{
public void Execute(IJobExecutionContext context)
{
Program.form.closeForm();
}
}
}
上面代码中，Program.form并不是开始创建的那个窗体，而是在Program类文件中创建的静态Form。为什么另创建一个静态Form？涉及到子线程关闭主线程问题
using System; using System.Collections.Generic; using System.Linq; using System.Windows.Forms;namespace winform状态栏
{
static class Program
{public static Form1 form; /// <summary> /// 应用程序的主入口点。 /// </summary> [STAThread] static void Main() { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); form = new Form1(); Application.Run(form); } }}
Form.cs文件里引用Quartz（using Quartz;）
然后是关闭按钮（Button）的事件
using Quartz; using System; using System.Text.RegularExpressions; using System.Windows.Forms;namespace winform状态栏
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}private void button_close(object sender, EventArgs e) { //cron表达式 参考 http://www.cnblogs.com/sunjie9606/archive/2012/03/15/2397626.html QuartzManager.AddJob<stopjob>("每隔5秒", "*/5 * * * * ?");//每隔5秒执行一次这个方法 } private delegate void CloseForm();//设计到多线程，子线程去控制主线程的控件，InvokeRequired值为true，用到定义委托，使得这个控制行为成为主线程的行为 public void closeForm() { if (this.InvokeRequired) { this.BeginInvoke(new CloseForm(closeForm)); } else { this.Close(); } } }}
关于执行stopjob的时间，我这里是用的每隔5秒执行一次，具体的解释在另一位博主那里有介绍
http://www.cnblogs.com/sunjie9606/archive/2012/03/15/2397626.html
其中C5.dll、Common.Logging.dll、Quartz.dll文件的链接http://pan.baidu.com/s/1hsBn1Bm（如果失效联系博主）
我学习Quartz.Net时用的是winform，大家可以试试别的，这样关于线程的问题应该就可以避免，这也是我没有想到的问题
