The ValidationResults type is a collection of ValidationResult objects. Each ValidationResult object contains a report that includes references to the Validator instance, the object that was validated, and error messages.
The ValidationResults.FindAll method filters a ValidationResult object and eliminates results that do not match the tags provided by the user. This method returns a new ValidationResults object that contains the desired information and leaves the original object unchanged.
The ValidationResults.IsValid property returns True if the validation passed and returns False if the validation failed.
The following table lists the properties of the ValidationResult class.
