DateTime CompareTo operation throwing error

Question

I am trying to compare current date with a calculated date from offset as shown below. The line throws an exception, enters catch block but exception is null. I cannot find what is the exception because of it

DateTime.UtcNow.Date.CompareTo(new UtcDateTime(startDate.AddDays(activity.DueInDaysOffset.GetValueOrDefault()))) > 0

startDate is date from DB

activity.DueInDaysOffset is an integer - positive/negative.

UtcDateTime is a class from 'Microsoft.CommonDataService' used for conversion.

What could be the issue?

Please at least post a complete code sample. And what is `UtcDateTime`. What's `activity`? How are we supposed to answer without knowing any of that? — Sach, Aug 24 '17 at 18:10
activity.DueInDaysOffset is just an integer, positive or negative. UtcDateTime is a class used for conversion — Ravi Sankar Rao, Aug 24 '17 at 18:11
You should post a [Minimal, Complete, and Verifiable example](https://stackoverflow.com/help/mcve). — Sach, Aug 24 '17 at 18:12
@Sach can you explain why you mark it as a null reference exception. Do you think i was so dumb to post a null reference exception here ? — Ravi Sankar Rao, Aug 24 '17 at 18:16
@Sach The execution of this line throws error, it enters catch block, but the exception object is null. I cannot find what is the exception and you are marking it as null reference exception. — Ravi Sankar Rao, Aug 24 '17 at 18:18
@RaviSankarRao you should take it up with Servy who did so. As per your second question, well, it remains to be seen. — Sach, Aug 24 '17 at 18:18
@Sach the post is minimal, complete. This is iniside a function that takes activity and start date as parameters. And i have edited the question — Ravi Sankar Rao, Aug 24 '17 at 18:19
@servy I suggest you to read the post again before marking it as a duplicate. — Ravi Sankar Rao, Aug 24 '17 at 18:22
@RaviSankarRao The alternative is your question being closed as unclear, because the question is a real mess. — Servy, Aug 24 '17 at 18:25
@Servy Great...Thanks for your help guys. This was an awesome learning. — Ravi Sankar Rao, Aug 24 '17 at 18:26

Without knowing the rest of your code, I would guess that either startDate or activity is null. Verify that both variables have values.

Of-course i had checked them. The problem is the execution throws error, enters catch block and the exception object is null. – Ravi Sankar Rao Aug 24 '17 at 18:13
Exception objects are never null. Maybe you checked too early. – BMI24 Aug 24 '17 at 18:16
