problemi in model binding and validation

Question

Hello! It looks like you have a controller with a route defined as [Route("/book/{Id?}")] . This route indicates that the controller is expecting a parameter called Id , which is optional due to the ? signifying it's nullable. When a request is made to this route, the Id parameter will be bound from the URL. Model binding is the process of mapping data from an HTTP request to action method parameters in your application. In this case, the Id parameter in the URL will be bound to the corresponding parameter in your controller method. Validation, on the other hand, ensures that the data being bound is correct and meets certain criteria. You can apply data annotations or custom validation logic to validate the incoming data before further processing. If you encounter any issues with model binding or need to validate the Id parameter, you can implement validation logic in your controller or use data annotations in your model to enforce specific rules. Let me know if you need further clarification or examples on how to handle model binding and validation in this context!
