/*====================================================================
虽然简单,但是我们很少写基于这样的应用,我偶尔看到这篇文章,就顺手摘录下来了

通过.NET平台编写和发布简单的Windows Service是一件很方便的事情.
新建一个(VB.NET/C#)项目,选择Windows Service应用..然后在OnStart类里就可以添加代码了.
如果想实现定时运行,活实时监听的功能,可以用.NET 提供的TIMER类.
以下是代码片段.
=====================================================================*/


private void theTimer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
{
if (!ExCondition())
{ return;
}
try
{
theTimer.Enabled = false;
MyTransaction();

}
catch(Exception es)
{
WriteLog(es.Message);
}
theTimer.Enabled = true;
}

//检测执行条件
private bool ExCondition()
{
DateTime dtNow = DateTime.Now;
if(this.currentmode.Equals("auto"))
{


string[] frev = this.freqvalue.Split(''-'');

switch( this.freq)
{

case "2"://2－每小时
if( (dtNow.Minute == 59)&(dtNow.Second< 30))
{
return true;
}

break;
case "4"://4－每天，
if((dtNow.Hour == int.Parse(frev[1]))&(dtNow.Minute == int.Parse(frev[2]))&(dtNow.Second<30))
{
return true;
}

break;
case "8"://8－每周，
int we = int.Parse(frev[0].Substring(1,1));
if((dtNow.DayOfWeek.ToString().Equals(Week[we]))&(dtNow.Hour == int.Parse(frev[1]))&(dtNow.Minute == int.Parse(frev[2]))&(dtNow.Second<30))
{
return true;
}
break;
case "16"://16－每月，
int mm = int.Parse(frev[0].Substring(1,frev[0].Length-1));
if((dtNow.Day == mm)&(dtNow.Hour == int.Parse(frev[1]))&(dtNow.Minute == int.Parse(frev[2]))&(dtNow.Second<30))
{
return true;
}

break;
default://无触发
return true;
break;
}
}
else
{
switch(this.startpoint)
{
case "0":
return true;
break;
default:
string[] st = startpoint.Split(''-'');
if((dtNow.Hour == int.Parse(st[0]))&(dtNow.Minute ==int.Parse(st[1]))&(dtNow.Second<30))
{
return true;
}
break;


}
}

return false;
}

注册你的Windows Service程序.
用InstallUtil IASserver.exe (这个文件默认在C:\WINNT\Microsoft.NET\Framework\v1.1.4322下)

InstallUtil IASserver.exe
InstallUtil IASserver.exe /u (卸载)
