You can also register custom model binders by decorating the model class with the ModelBinder attribute, which means
that you don’t need to use the Global.asax file. In Listing 24-40, you can see how I have specified
AddressSummaryBinder as the binder for the AddressSummary class.
Listing 24-40. Using the ModelBinder Attribute in the AddressSummary.cs File
using System.Web.Mvc;
using MvcModels.Infrastructure;
namespace MvcModels.Models {
}
[ModelBinder(typeof(AddressSummaryBinder))]
public class AddressSummary {
public string City { get; set; }
public string Country { get; set; }
}
Summary
In this chapter, I introduced you to the workings of the model binding process, showing you how the default model binder
operates and the different ways in which the process can be customized. Many MVC Framework applications will only need the
default model binder, which works nicely to process the HTML that the helper methods generate. But for more advanced
applications, it can be useful to use custom binders that create model objects in a more efficient or specific way. In the next
chapter, I show you how to validate model objects and how to present the user with meaningful errors when invalid data is
received.
