    Inherited = false)]
publicabstractclassValidatorAttribute : BaseValidationAttribute

[AttributeUsageAttribute(AttributeTargets::Class|AttributeTargets::Method|AttributeTargets::Property|AttributeTargets::Field|AttributeTargets::Parameter, AllowMultiple = true, 
    Inherited = false)]
publicref classValidatorAttributeabstract : public BaseValidationAttribute

publicabstractclass ValidatorAttribute extends BaseValidationAttribute

Remarks

Multiple validator attributes can be specified for a language element.

All the rules will be applied as an "And" composition unless the ValidatorCompositionAttribute overrides this behavior.

A ruleset can be specified for the attribute, as well as message overrides (either literal or resource based).
