我正在编写一个Windows服务，它将在用户定义的时间将报告导出到Excel。用户可以选择使用以下选项运行报告：
注意（我的SQL Server数据每秒更新一次＆amp;我编写了一个Windows应用程序，用户将从中配置上面的，将保存到xml中）
我的Windows服务配置为在TimerInterval 30000运行。
我的问题是： 1.如果用户将开始时间设置为10:00 PM，将结束时间设置为12:00 AM，将每日时间设置为12:00 AM，则下面的代码将失败，因为我正在使用system.datetime.now
DateTime tempDailyTime=DateTime.ParseExact(DailyTime,"HH:mm:ss tt",CultureInfo.InvariantCulture);
string curTime = System.DateTime.Now.ToString("HH:mm:ss tt");
DateTime tempCurrentTime = DateTime.ParseExact(curTime, "HH:mm:ss tt", CultureInfo.InvariantCulture);
if (tempCurrentTime >= tempDailyTime)
{
string tempFilename=Convert.ToString(tempDailyTime.TimeOfDay).Replace(":","-")+".xlsx";
if (!File.Exists(tempDir + "\\DailyTime" + "\\" + ReportName + "_" + tempFilename))
{
GenerateReportWithStartTimeandEndTime(ReportName,ReportID,ConnectionString,ReportColumnName,ReportBQuery,StartTime,EndTime,DailyTime,tempDir+"\\DailyTime",tempFilename);
}
}
用于生成每日，每周，每月，每年我已指定运行报告的预定时间
DateTime scheduleTime = new DateTime（currentTime.Year，currentTime.Month，currentTime.Day，23,59,59,999）;
在到达下面的代码部分之前经过计时器，如果datetime改变，它将生成一个空白报告。 我的每日报告生成代码如下：
if (Daily == "true")
{
DateTime currentTime = DateTime.Now;
int intervalToElapse = 0;
DateTime scheduleTime = new DateTime(currentTime.Year, currentTime.Month, currentTime.Day, 23, 59, 59, 999);
if (currentTime <= scheduleTime)
intervalToElapse = (int)scheduleTime.Subtract(currentTime).TotalSeconds;
else
intervalToElapse = (int)scheduleTime.AddDays(1).Subtract(currentTime).TotalSeconds;
_DailyTimer = new System.Timers.Timer(intervalToElapse);
if (_DailyTimer.Interval == 0)
{
//GenerateDailyReport(ReportName, ReportID, ConnectionString, ReportColumnName, ReportBQuery, StartTime, EndTime, DailyTime, tempDir + "\\DailyTime", tempFilename);
}
}
if (Weekly == "true")
{
//GenerateWeeklyReport(ReportName, ReportID, ConnectionString, ReportColumnName, ReportBQuery, StartTime, EndTime, DailyTime, tempDir + "\\DailyTime", tempFilename);
}
if (Monthly == "true")
{
//GenerateMonthlyReport(ReportName, ReportID, ConnectionString, ReportColumnName, ReportBQuery, StartTime, EndTime, DailyTime, tempDir + "\\DailyTime", tempFilename);
}
if (Yearly == "true")
{
//GenerateYearlyReport(ReportName, ReportID, ConnectionString, ReportColumnName, ReportBQuery, StartTime, EndTime, DailyTime, tempDir + "\\DailyTime", tempFilename);
}
要生成报告的数据来自以下xml文件：

我需要建议如何处理这个或我做错了什么。
