Question

I have the following (greatly simplified) classes:

public class Customer {
    [Required(ErrorMessageResourceName="Required", ErrorMessageResourceType=typeof(ResourcesCommon.ValidationStrings))]
    public string LastName { get; set; }
}

public class SalesCustomer : Customer {
    ...
}

I have some validation code that loops through SalesCustomer properties. Each property is evaluated with this:

 var validators = property.GetCustomAttributes(typeof(ValidationAttribute), true);

The problem is that the Required attribute is not getting returned when I look at the LastName property on the SalesCustomer type but it does work fine when I look at the Customer type. This is confusing since the GetCustomerAttribute() method explicitly wants a boolean indicating that the inherited attributes will be returned.

Answer 1

I believe that it will only return attributes from overridden parent members, not shadowed parent members.

Make the base property virtual and the child property overrrides.
