委托 C# 添加定时任务

qq_29783739 2015-08-17 05:53:58

session 运行时从数据库拿出数据判断时间为今天的就给他新建一个Timer控件现在的问题是绑定委托的时候还没到时间就直接运行了方法求改动方案
代码如下

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using DCModel;

public class Global : System.Web.HttpApplication
{
public Global()
{
}
public static List<DCModel.Task_Content> ss()
{

DataClassesDataContext dc = new DataClassesDataContext();
var resurt = (from p in dc.Task_Content
where p.ReleaseState == 1
select p).ToList();
return resurt;
}

void Application_Start(object sender, EventArgs e)
{

}

public void time(string sj, int id, string take)
{
System.Timers.Timer myTimer = new System.Timers.Timer();
DateTime dt = DateTime.Now;
DateTime strTime;
strTime = Convert.ToDateTime(sj);
string dtAfter= strTime.ToString();
DateTime dtTime = Convert.ToDateTime(dtAfter);
TimeSpan ts1 = new TimeSpan(dt.Ticks);
TimeSpan ts2 = new TimeSpan(dtTime.Ticks);
TimeSpan ts = ts1.Subtract(ts2).Duration();
string dateDi = ts.TotalSeconds.ToString();
string strDatedi = dateDi.Substring(0, dateDi.IndexOf('.'));
int dateDiff = Convert.ToInt32(strDatedi);
myTimer.Interval = dateDiff * 1000;
myTimer.Enabled = true;
myTimer.Elapsed += OnTimedEvent(id, take);
GC.KeepAlive(myTimer);
}

void Application_End(object sender, EventArgs e)
{

}

void Application_Error(object sender, EventArgs e)
{

}
void Session_Start(object sender, EventArgs e)
{
try
{
List<DCModel.Task_Content> resurt = ss();

foreach (var a in resurt)
{
DateTime aa = (DateTime)a.ReleaseStartTime;

if (aa.Subtract(DateTime.Now).Days == 0)
{

time("" + aa.ToString("hh:mm"), a.ID, a.TaskID);

}

}
}
catch (Exception ex)
{
throw ex;
}
}

void Session_End(object sender, EventArgs e)
{

}
private static System.Timers.ElapsedEventHandler OnTimedEvent(int id, string take)
{
DataClassesDataContext dc = new DataClassesDataContext();
var user = dc.Task_Content.Single(u => u.ID == id);
user.ReleaseState = 0;
dc.SubmitChanges();

var users = dc.Task.Single(u => u.TaskID == take);
users.ReleaseState = 0;
dc.SubmitChanges();

return null;
}
}
