Calculating date differences in C# (DateDiff for c#??)

[Paul Aspinall]

Hi
I want to calculate the difference between 2 dates in C#.

I know there is a function in VB, called DateDiff, but I don't want to ref
the VB library, and want to try to do it natively in C#.

Is there a similar function available in the C# or standard .NET libraries?


Thanks

Look up the Subtraction operator of the DateTime and TimeSpan structures.
You can get the difference between combinations of DateTimes, TimeSpans
returned as either DateTimes or TimeSpans

Look at System.DateTime and System.TimeSpan.

DateTime dtThen = new DateTime (2004, 1, 1);
DateTime dtNow = DateTime.Now;
TimeSpan ts = dtNow - dtThen;

DateTime also contains functions like AddHours & AddMinutes. I don't think
there is any direct equivalent to DateDiff, but you can certainly accomplish
the same thing in other ways using DateTime and TimeSpan.
