c# - Datediff getting the date inbetween 2 dates and bind it to a gridview

I have a table with 'dateborrowed' and 'datereturned' column. What I want to do is I want to get the value in between 'datereturned' and 'dateborrowed' and bind it to another column in another table. Also how can I do it using datediff function? I'm still learning it in the meantime. Any help would be greatly appreciated.

Thanks in advance!!

With C#.NET you can subtract one DateTime from another, resulting in a TimeSpan. For example:

TimeSpan timespan = (DateTime.Now - new DateTime(2011, 1, 1));

If you want a date in between two dates, you can then add half of this timespan to one of the dates:

TimeSpan timespan = (DateTime.Now - new DateTime(2011, 1, 1));
DateTime inBetween = DateTime.Now.AddDays(timespan.TotalDays / 2);
