New Post: Non-property oriented validation

I created a sample Extension method... I hope that it could help someone.

         public static void ObjectRule<T>(this AbstractValidator<T> validator, Func<T, string> customValidation)
         {
             validator.Custom(x =>
                                  {
                                      string error = customValidation(x);
                                      if (string.IsNullOrEmpty(error))
                                          return null;
                                      else
                                          return new ValidationFailure(string.Empty, error);
                                  }
                 );
         }

Now the could would be like:

fluentValidator.ObjectRule("TEST OBJECT ERROR");

Any better (cleaner) ideas?


Two questions (do you want me to create new topics?):

1. Is there an ValidationRule implementation that uses DataAnnotations?
2. Do you know any good IDataErrorInfo wrapper/adapter (I am currently working at it) :)
