What are some examples of custom model binders in ASP.NET MVC?

Custom model binders in ASP.NET MVC allow you to bind complex types from HTTP requests. For example, you can create a binder for a custom object like a 'Product' that takes parameters from the request.

Can you show me a code example of a custom model binder?

Sure! Here's a simple example:

public class ProductModelBinder : IModelBinder
{
    public object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
    {
        var product = new Product();
        product.Name = bindingContext.ValueProvider.GetValue("Name").AttemptedValue;
        product.Price = decimal.Parse(bindingContext.ValueProvider.GetValue("Price").AttemptedValue);
        return product;
    }
}

How do I register this custom model binder in my application?

You can register the custom model binder in the Global.asax file like this:

ModelBinders.Binders.Add(typeof(Product), new ProductModelBinder());

What are the benefits of using custom model binders?

Custom model binders provide flexibility in handling complex data types, improve code organization, and enhance reusability across your application.
