How does model binding work with collections in ASP.NET MVC?

In ASP.NET MVC, model binding allows you to map form data to a collection of objects. When you submit a form with a collection, the framework automatically binds the data to a list or array in your model.

Can you give me an example of how to bind a list of items?

Sure! If you have a form with multiple input fields named 'Items[0].Name', 'Items[1].Name', etc., the model binder will create a list of 'Item' objects with the corresponding names.

What if I want to bind a collection of complex objects?

You can bind collections of complex objects in the same way. Just ensure your input names follow the pattern 'Items[index].PropertyName' for each property of the complex object.

Are there any limitations I should be aware of?

Yes, one limitation is that the collection must be a property of the model being bound. Also, ensure that the index is sequential; otherwise, the binding may not work as expected.
