string date="23-06-1999";

I have a date like this, now my requirement is i want to check the condition if the date is in "MM-dd-yy" format or not.

If the date is in the same format insert the records otherwise i want to display error message...

Can any body help me out of this...


along with DateTime.TryParseExact, you can make use of regular expressions.
use below expression for mm-dd-yyyy.
/^(0[1-9]|1[012])[/ -.](0[1-9]|[12][0-9]|3[01])[/ -.](19|20)\d\d+$/

refer article The 30 Minute Regex Tutorial[^] for more on regular expressions.

hope it helps.

Thanks Maciej. :-)
You can use DateTime.TryParseExact method and pass the appropriate dateformat. If it succeeds you can do your further processing.

Go through the below MSDN link for more info.[^]

All the best.

Just use DateTime.TryParseExact Method[^].
You can optionally check if formatted parsed date is equal to input string.

Or you can use simple regex like this:
In case you want to check if input is in 100% correct format, you should extend this pattern.
