How do you do custom validation on FileHelpers?

Question

I want to throw an exception to say that we have an invalid email address as I dont want to proceed until we get a valid email address. Is this where I want to do it and if so, how?

void Engine_AfterReadRecord(EngineBase engine, FileHelpers.Events.AfterReadEventArgs<UserInfoFromAd> e){
     bool isEmailValid = IsEmailValid(e.Record.Email);
     if (!isEmailValid){
        //I want to throw exception
     }
 }

Answer 1

What seems to be the problem? Just throw it:

if (!isEmailValid)
{
    throw new InvalidDataException("Email is not valid.");
}
