C＃VSTO Wordアドインでページ番号の横にヘッダーとフッターのテキストを設定する方法は？

Question

C＃VSTO Wordアドインのページ番号の横にヘッダー/フッターテキストを設定する必要があります。私はテキストを挿入することができますまたは私はページ番号を挿入することができますが、私は両方を行うと、私はどちらか他のページの特定の側面にとどまることができません。

たとえば、奇数ページでは、次のようにヘッダーが必要です。TITLE PageNumber。偶数ページでは、ヘッダーが必要です：PageNumber著者。フッターは同じである必要があります。奇数ページのヘッダーは、左に揃えられたテキスト、右に揃えられたページ番号です。偶数ページのヘッダーは、ページ番号が左側に揃えられ、著者が右側に揃えられます。フッターは常に中央に配置されます。

C＃VSTO Wordアドイン（MSVS 2015）でこのテキストとページ番号の配置を取得するにはどうすればよいですか？ （私はこの詳細な支援はSOやネットのどこにもありません）

このソリューションは、アライメント、アプリケーションレベルの選択、範囲操作、タブアライメントの微妙なダンスです。これは私が開発した機能です。ドキュメント内に3つのセクション（タイトルページ、本文、および終了ページ）を作成し、各セクションのヘッダー/フッターをフォーマットし、第1セクションと第3セクションからこれらのフィーチャーを削除します。ボディ、セクション。コードは説明のためにコメントされています：（注：ページ番号は最初に挿入しなければならず、その後にテキストを配置しなければなりませんが、テキストはアプリケーション選択レベルで追加され、ヘッダー/フッターの範囲には直接追加されません）
