# Item メソッド

> ABBYY FineReader Engine API の Item メソッド — FineReader Engine コレクション内の 1 つの要素へのアクセスを提供する共通メソッド。

<Note>
  これは共通メソッドです。プラットフォーム固有の実装上の制限については、このメソッドを使用するオブジェクトのトピックに記載されています。
</Note>

このメソッドを使用すると、FineReader Engine のコレクション内の 1 つの要素にアクセスできます。すべての FineReader Engine コレクションで、このメソッドが使用されます。

<div id="c">
  ### C++
</div>

```cpp theme={null}
HRESULT Item(
  int              Index,
  I<ElementType>** Result
);
```

### C\#

```csharp theme={null}
I<ElementType> Item( int Index );
```

  ## パラメーター
</div>

Index

\[in] この変数には、このメソッドでアクセスされる要素のインデックスが格納されます。この値は 0 から要素数 - 1 までの範囲でなければなりません。要素数は、同じコレクションの Count プロパティから取得できます。

Result

\[out, retval] コレクション要素のインターフェイスへのポインターを受け取る、I\<ElementType>\* 型の変数です。ElementType は、コレクションを構成するオブジェクトの型です。

<div id="return-values">
  ## 戻り値
</div>

このメソッド固有の戻り値はありません。[ABBYY FineReader Engine 関数の標準戻り値](/ja/fine-reader/engine/api-reference/return-codes)が返されます。
