Hinweise
Wenn die CaseInsensitiveHashCodeProvider instance mithilfe dieses Konstruktors erstellt wird, wird der des Thread.CurrentCulture aktuellen Threads gespeichert. Vergleichsverfahren verwenden die gespeicherte Kultur, um die Groß- und Kleinschreibungsregeln zu bestimmen. Daher können Hashcodevergleiche je nach Kultur unterschiedliche Ergebnisse aufweisen. Weitere Informationen zu kulturspezifischen Vergleichen finden Sie unter Namespace System.Globalization und Globalisierung und Lokalisierung.
