プロパティ値

HtmlTableCell に格納されているセルを表す HtmlTableCellCollectionAn HtmlTableCell that represents a cell contained in the HtmlTableCellCollection.

次のコード例では、インデクサーを使用して、 HtmlTableCellオブジェクトで表されるテーブルのセルをHtmlTableCellCollectionコレクションから取得する方法を示します。The following code example demonstrates how to use the indexer to retrieve a cell of a table, represented by an HtmlTableCell object, from the HtmlTableCellCollection collection. 次に、セルが新しいコンテンツで更新されます。The cell is then updated with new content. オブジェクトによっCellsて表される行のプロパティがHtmlTableCellCollectionコレクションであることに注意してください。 HtmlTableRowNotice that the Cells property of a row represented by an HtmlTableRow object is the HtmlTableCellCollection collection.

注釈

このインデクサーを使用してHtmlTableCellHtmlTableCellCollectionコレクションからオブジェクトを取得します。Use this indexer to get an HtmlTableCell object from the HtmlTableCellCollection collection. 単純な配列表記HtmlTableCellを使用して、指定したインデックス位置にあるオブジェクトにアクセスできます。You can access an HtmlTableCell object at a specified index by using simple array notation.

注意

コレクションは0から始まります。したがって、コレクション内の最初の要素には、の0インデックス値が含まれています。The collection is zero-based; therefore, the first element in the collection contains an index value of 0.
