これは、LogParserが提供するAPIを使用して行うのは非常に簡単です。
LogParser2.2をダウンロードしてインストールします
COMライブラリ「MSUtility1.0TypeLibrary-LogParserInterfacescollection」への参照を追加します。ログを検索すると、リストがかなり劇的に絞り込まれました。
相互運用タイプが埋め込まれないように、参照のプロパティを変更します。これを行わないと、次のようなコンパイルエラーが発生します。相互運用機能タイプ'MSUtil.COMCSVOutputContextClassClass'を埋め込むことはできません。代わりに、該当するインターフェースを使用してください。
LogParserヘルプファイルの内容にはAPIの優れたリファレンスがありますが、コードにインラインで使用した部分を含めました。
