Get All Methods from List(Containing Method) using Reflection and Fill Methods to Dictionary

 public class ValidationDummyEntity
{
    public Int32 IntProperty { get; set; }
    public string StringProperty { get; set; }
    public DateTimeOffset DateTimeProperty { get; set; }
    public decimal DecimalProperty { get; set; }

}

public class DummyEntityValidator<T> : AbstractValidator<ValidationDummyEntity>
{
    public Dictionary<string, List<string>> GetValidationRuleNames()
    {
        Dictionary<string, List<string>> validationRulesNames = new Dictionary<string, List<string>>();

        if (typeof(T) == typeof(System.Int32))
        {
            // Add Validatin Rules for Int property type
            IRuleBuilderInitial<ValidationDummyEntity, Int32> ruleBuilderInt = RuleFor(q => q.IntProperty);

            IEnumerable businessObjectCollection = ruleBuilderInt as IEnumerable;

               MethodInfo addMethod = businessObjectCollection.GetType().GetMethods()
             .Where(m => m.Name == "Add" && m.GetParameters().Count() == 1).FirstOrDefault();
            foreach (object obj in businessObjectCollection as IEnumerable)
            {
                addMethod.Invoke(ruleBuilderInt, new object[] { obj });
            }

            validationRulesNames.Add("Int32", ruleBuilderInt);

            return validationRulesNames;
        }
    }
}` 

Using Fluient Library for validation :-

 public IRuleBuilderInitial<T, TProperty> RuleFor<TProperty>(Expression<Func<T, TProperty>> expression);

I need to add these action in validationRulesNames Dictionary

        ruleBuilderInt.NotEmpty();
        ruleBuilderInt.NotNull();
               ...... ans so on

here ruleBuilderInt after putting dot(.) containing more than 10 methods

How can I do that using Reflection, There is certain restriction for foreach loop here ?
