Poznámky
Při vytvoření CaseInsensitiveHashCodeProvider instance pomocí tohoto konstruktoru Thread.CurrentCulture je uložen aktuální vlákno. Postupy porovnání používají uloženou jazykovou verzi k určení pravidel dělení malých a malých a malých. Proto porovnání kódu hash mohou mít různé výsledky v závislosti na jazykové verzi. Další informace o porovnáních specifických pro jazykovou verzi najdete v System.Globalization tématech Obor názvů a Globalizace a lokalizace.
