How do I handle collections in ASP.NET MVC?

In ASP.NET MVC, you can handle collections by using model binding. You can create a model that contains a collection property, and the framework will automatically bind the incoming data to that collection.

Can you give me an example of a model with a collection?

Sure! Here's a simple example:

public class ShoppingCart {
    public List<Item> Items { get; set; }
}

public class Item {
    public int Id { get; set; }
    public string Name { get; set; }
}

How do I pass this collection to a view?

You can pass the collection to the view by including it in the model. For example:

public ActionResult Index() {
    var cart = new ShoppingCart { Items = new List<Item>() };
    return View(cart);
}

What about handling form submissions for collections?

For form submissions, ensure your input names are indexed, like Items[0].Name, so that model binding can correctly map the submitted data back to your collection.
