Question

How would you structure your code in the following scenario:

Several business objects (e.g.Person, House, etc), and between them, you need to validate the user inputs (which come in from textboxes). Would that go in either:

1. Each business object
2. The winforms codebehind
3. A seperate (static?) class.

Thanks

Answer 1

Each business object. I have classically made each one implement an IValidator interface that spits out all validation errors for the object.
