Validator Implementation

    public class Validator : IValidator
    {
        private readonly Dictionary<ValidationRules, IValidationRule> _rules;

        public Validator()
        {
            _rules = new Dictionary<ValidationRules, IValidationRule>();
        }

        public void AddRule(ValidationRules rule, IValidationRule validator)
        {
            _rules.Add(rule, validator);
        }

        public IValidationRule GetRule(ValidationRules rule)
        {
            IValidationRule value;
            _rules.TryGetValue(rule, out value);
            return value;
        }

        public void RemoveRule(ValidationRules rule)
        {
            _rules.Remove(rule);
        }
    }

ValidationRule Interface

    public interface IValidationRule
    {
        bool IsValid(string text);
    }
