Comparer.DefaultInvariant フィールド
アセンブリ: mscorlib (mscorlib.dll 内)


比較プロシージャは、並べ替え順序と大文字と小文字の規則を決定するために、CultureInfo.InvariantCulture を使用します。文字列比較の結果は、カルチャに応じて異なる場合があります。カルチャ固有の比較の詳細については、System.Globalization 名前空間のトピックおよび「エンコーディングとローカリゼーション」を参照してください。

Comparer に関連付けられているカルチャに応じて、Compare が返す値が変わる方法については、次のコードの例を参照してください。
