The collection of all top-level fields in the form.

Items in this collection can be referenced by partial field name or by zero-based index. The type of the value you pass is used to determine whether you are looking by name or by index.

So if you intend to reference an item by index, pass a number. If you intend to reference an item by name, pass a string. In cases where a string is passed but no matching items could be found, an attempt will be made to convert the string to a number and return an item with that index.

As with all collections, you can use the Count property to determine the number of items contained, and you can iterate through the collection using the standard methods appropriate to the language you are coding in.
