如何确认当前时间在特定时间范围内? [英] How can I ckeck that the current time is within a specific time range?

问题描述

我需要比较当前时间是否在特定范围内.我尝试了以下

I need to compare that the current time is within a specific range. I've tried the following

DateTime currentTime = DateTime.Now; 
int Comaprestart = DateTime.Compare(currentTime, startTime);
int CompareEnd = DateTime.Compare(currentTime,endTime);
if ((Comaprestart >= 0) && (CompareEnd <= 0))
     LinkBtnQuiz.Enabled = true;

它无法正常工作.例如，我的结束时间等于"2014-06-08 13:30:00.000"，当前时间等于"2014-06-08 13:12:00.000"，但是我得到CompareEnd = 1，但它应该为-1当前时间早于结束时间.

It doesn't work right. for example I have the end time equal '2014-06-08 13:30:00.000' and the current time equal '2014-06-08 13:12:00.000' but I get CompareEnd=1 while it should be -1 as the current time is earlier than the end time.

关于导致错误的原因有什么想法?

Any idea of what is causing the error??

推荐答案

您可以更轻松地做到这一点:

you can do it easier:

if(currentTime >= startTime && currentTime <= endTime)
{
   LinkBtnQuiz.Enabled = true;
}
