Açıklamalar
CaseInsensitiveHashCodeProvider Örnek bu oluşturucu kullanılarak oluşturulduğunda, Thread.CurrentCulture geçerli iş parçacığının kaydedilir. Karşılaştırma yordamları büyük/küçük harf kurallarını belirlemek için kaydedilmiş kültürü kullanır; Bu nedenle, karma kod karşılaştırmaları kültüre bağlı olarak farklı sonuçlara sahip olabilir. Kültüre özgü karşılaştırmalar hakkında daha fazla bilgi için bkz System.Globalization . ad alanı ve Genelleştirme ve Yerelleştirme.
