# LayoutBlocks オブジェクト (ILayoutBlocks インターフェイス)

> ABBYY FineReader Engine API の LayoutBlocks オブジェクト (ILayoutBlocks インターフェイス) — Layout 上の Block オブジェクトのコレクション。標準の FineReader Engine コレクション機能に加えて、IndexOf および型指定された AddNew を提供します。

このオブジェクトは、レイアウトブロック ([Block](/ja/fine-reader/engine/api-reference/layout-related-objects/block) オブジェクト) のコレクションを表します。[Layout](/ja/fine-reader/engine/api-reference/layout-related-objects/layout) オブジェクトのサブオブジェクトであり、Layout ブロックの格納先として機能します。

このオブジェクトは標準的なコレクション機能を提供します。詳細については、[コレクションの操作](/ja/fine-reader/engine/guided-tour/advanced-techniques/programming-aspects/working-with-collections)を参照してください。

* ABBYY FineReader Engine コレクションのインデックスは 0 から始まります。
* C# の foreach ステートメント (Visual Basic .NET では for each) を使用してコレクションを操作できます。
