CultureInfo.CompareInfo プロパティ
カルチャの文字列を比較する方法を定義する CompareInfo を取得します。
Public Overridable ReadOnly Property CompareInfo As CompareInfo
[C#]
public virtual CompareInfo CompareInfo {get;}
[C++]
public: __property virtual CompareInfo* get_CompareInfo();
[JScript]
public function get CompareInfo() : CompareInfo;
プロパティ値
カルチャの文字列を比較する方法を定義する CompareInfo 。
解説
ユーザーは、[コントロール パネル] の [地域と言語のオプション] (オペレーティング システムによっては [地域のオプション] または [地域]) を使用して、Windows の現在のカルチャに関連付けられた値の一部をオーバーライドすることもできます。たとえば、ユーザーが別の形式で日付を表示したり、カルチャの既定の通貨以外の通貨を使用したりすることを選択する場合があります。
UseUserOverride が true であり、指定されたカルチャが Windows の現在のカルチャと一致する場合、 CultureInfo はこれらのオーバーライドを使用します。これには、 DateTimeFormat プロパティによって返される DateTimeFormatInfo インスタンスのプロパティ、 NumberFormat プロパティによって返される NumberFormatInfo インスタンスのプロパティ、および CompareInfo プロパティによって返される CompareInfo インスタンスのプロパティのユーザー設定値が含まれます。ユーザー設定が CultureInfo に関連付けられたカルチャと互換性を持たない場合 (たとえば、選択した暦が OptionalCalendars のいずれでもない場合)、メソッドの結果とプロパティの値は未定義になります。
セキュリティの決定が文字列の比較や大文字/小文字の変換操作に依存する場合は、システムのカルチャ設定にかかわらず一定の動作を保証するために InvariantCulture を使用してください。
使用例
