# LayoutBlocks Object (ILayoutBlocks Interface)

This object represents a collection of layout blocks ([Block](/fine-reader/engine/api-reference/layout-related-objects/block) objects). It is a subobject of a [Layout](/fine-reader/engine/api-reference/layout-related-objects/layout) object, and it serves as a storage of Layout blocks.

The object provides standard collection functionality. See [Working with Collections](/fine-reader/engine/guided-tour/advanced-techniques/programming-aspects/working-with-collections) for details.

* 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.
