Is it a good practice to throw an exception on Validate() methods or better to return bool value?

Question

Is it recommended or not to throw exceptions from Validation methods like:

ValidateDates(); ValidateCargoDetails(); 

Apart from this : Is there a robust validation design pattern often used?

Answer 1

I would suggest returning a ValidationResult object containing ValidationFailures. You should never use exceptions as part of your logical coding. Exceptions are for exceptions

Answer 2

I would say it all depends on what/how you are doing the validation. But at the end of the day a developer can always choose to ignore a returned result (this is the problem with them), they can't ignore an exception without writing explicit code to do so.
