Two DateTime Validate if it is within the range of two DateTime

Question

I'am struggling on how to make this on code. please help. I use c#

Here's the data:

    DateTime date_from = Convert.ToDateTime("2018/08/22 12:20:00");
    DateTime date_to =  Convert.ToDateTime("2018/08/28 07:25:00");

    DateTime other_date_from =  Convert.ToDateTime("2018/08/24 00:20:00");
    DateTime other_date_to=  Convert.ToDateTime("2018/08/25 00:21:00");

Now, I'd like to check if the data from date_from and date_to is within the range of other_date_from and other_date_to.

For example.

This datetime

"2018/08/22 12:20:00 to 2018/08/28 07:25:00" : August 22 12:20 PM to August 28 07:25 AM

is within the range of

"2018/08/24 00:20:00 to 2018/08/25 00:21:00" August 24 12:20 AM to August 25 12:21 AM

If its within the range, it returns true, if not return false.

What does your code look like so far? And does the date range you provide have to fully overlap the range to be considered "in range"? — ProgrammingLlama, Aug 26 '18 at 02:20

This simple condition will do the trick !

date_from <= other_date_to && date_to >= other_date_from

It's bit of head scratcher sometimes...

            DateTime date_from = Convert.ToDateTime("2018/08/22 12:20:00");
            DateTime date_to = Convert.ToDateTime("2018/08/28 07:25:00");

            DateTime other_date_from = Convert.ToDateTime("2018/08/24 00:20:00");
            DateTime other_date_to = Convert.ToDateTime("2018/08/25 00:21:00");

            bool bInRange = ((other_date_from > date_from & other_date_from < date_to) &
                            (other_date_to > date_from & other_date_to < date_to));
