Sample code using DateTime.TimeOfDay

DateTime timeNow = DateTime.Now;
DateTime fromTime = new DateTime(2015, 11, 14, 08, 00, 00);
DateTime toTime = new DateTime(2015, 11, 14, 14, 30, 00);

if (TimeSpan.Compare(timeNow.TimeOfDay, fromTime.TimeOfDay) == 1 && TimeSpan.Compare(timeNow.TimeOfDay, toTime.TimeOfDay) == -1)  
{
}

In the above code , if the variable timeNow is between 08:00:00 to 14:30:00 then the condition become true.

1 represents time1 > time2
0 represents time1 = time2
-1 represents time1 < time2

If you are trying to compare the difference between the two times you should use the Timespan object.

By using a Timespan you are able to get the difference in seconds, hours and days etc.

Check out the following for more information:

Use the TimeOfDay property:

http://msdn.microsoft.com/en-us/library/system.datetime.timeofday.aspx

This gives you the time portion of the value without the date portion.

You can use DateTime.TimeOfDay to get just the time part to compare. This is essentially the same as if you did d - d.Date.

if (DateTime1.TimeOfDay > DateTime2.TimeOfDay)
{
    MessageBox.Show("DateTime1 is later");

Try something like this:

TimeSpan ts = d1 - d2;
int totalSecondNumber = ts.TotalSeconds;

TimeSpan is a difference between to dates. It gives you properties like TotalSeconds, TotalHours and so on or just Seconds, Hours, etc
