# IntsCollection Object (IIntsCollection Interface)

This object represents a collection of [int](/fine-reader/engine/guided-tour/advanced-techniques/programming-aspects/working-with-properties) type variables. It serves as a storage to pass various sets of parameters into those ABBYY FineReader Engine functions that require them. It may also be return value of ABBYY FineReader Engine methods.

* The indexing of ABBYY FineReader Engine collections starts with 0.
* The foreach statement in C# (for each in Visual Basic .NET) can be used to manipulate the collection.
