ValidationResults obj = new ValidationResults(validationResult, base.Application.Model);
bool flag = validationResult.State != ValidationState.Invalid;

VB.NET

Dim validationResult As RuleSetValidationResult = Validator.RuleSet.ValidateAllTargets( _
ObjectSpace, ObjectSpace.GetObjectsToSave(False), ContextIdentifier.Save)
