Get Properties of container class using .net reflection

I have a class contains set of properties, one of the properties is a class type as below :

public class ProgramData
{
    public string code { get; set; }
    public string message { get; set; }

    public string program_id { get; set; }
    public string email { get; set; }
    public string first_name { get; set; }
    public string last_name { get; set; }

    public GeneralSetup general_setup { get; set; }
}

public class GeneralSetup
{
    public string store_name { get; set; }

    public bool store_enabled { get; set; }

    public bool promotions_enabled { get; set; }

    public bool barcode_scan_enabled { get; set; }

    public bool barcode_generate_enabled { get; set; }

}

i have a generic method [because i have set of classes] to validate the properties and i use reflection to get props name and value dynamically and its working fine, but the problem is when it validates general_setup property it gets its props and start validating them. based on my business rules if it string.empty i want to set [code and message] props of the container class and i can not get this props at this level. any ideas? thanks

public T ValidateObjectFields<T>(T entity) where T : class
    {
        Type objType = entity.GetType();

        foreach (PropertyInfo property in properties)
        {
            object propValue = property.GetValue(entity, null);
            var elems = propValue as IList;
            if (elems != null)
            {
                foreach (var item in elems)
                    ValidateObjectFields(item);
            }
            else
