MVC2 DataAnnotations with Server-side validation

Question

How do you validate an entity containing DataAnnotations without using the MVC library? Using Model.IsValid is fine when you're within the Presentation layer, but what about when you want to ensure the model is valid in the Domain/Business layer? Do I need a separate validation framework, or is there an easy way I'm missing?

Thanks for any help,

Mark

Answer 1

I suppose you mean ModelState.IsValid by Model.IsValid, right? Well, DataAnnotions don't depend on MVC at all, so you can always use the IValidatableObject interface.

Or perhaps the Validator class will be more appropriate, by using Validator.ValidateObject(object, ValidationContext).
