true if the object validates; otherwise, false.

This method tests each validation attribute in the validationAttributes parameter against the value parameter. If the validationResults parameter is not null, this method adds a ValidationResult object for each validation failure to the validation results collection. If the validationResults parameter is null, this method does not add a ValidationResult object to the collection. If a RequiredAttribute attribute is included in the validationAttributes parameter, the RequiredAttribute attribute is evaluated first.
