FluentValidation Call RuleSet and Common Rules

Question

public class ValidProjectHeader : AbstractValidator
    {
        public ValidProjectHeader()
        {         


        

Answer 1

I have found one way to do it by adding a second validator.Validate to the CallValidation(string ruleSet) method it is as follows

public virtual bool CallValidation(string ruleSet)
        {
            Errors = new List();
            ValidatorAttribute val = this.GetType().GetCustomAttributes(typeof(ValidatorAttribute), true)[0] as ValidatorAttribute;
            IValidator validator = Activator.CreateInstance(val.ValidatorType) as IValidator;
            FluentValidation.Results.ValidationResult result = validator.Validate(new FluentValidation.ValidationContext(this, new PropertyChain(), new RulesetValidatorSelector(ruleSet)));
            FluentValidation.Results.ValidationResult resultCommon = validator.Validate(this);
            IsValid = (result.IsValid && resultCommon.IsValid);
            Errors = result.Errors.Union(resultCommon.Errors).ToList();
            return IsValid;
        }
