Açıklamalar

Bu sınıf, arabiriminin varsayılan uygulamasıdır IComparer . CaseInsensitiveComparer sınıfı, büyük/küçük harfe duyarsız dize karşılaştırmaları gerçekleştiren arabiriminin IComparer uygulamasıdır. System.Collections.Generic.Comparer<T> bu sınıfın genel eşdeğeridir.

Karşılaştırma yordamları, aksi belirtilmedikçe geçerli iş parçacığının kullanır Thread.CurrentCulture . Dize karşılaştırmaları kültüre bağlı olarak farklı sonuçlara sahip olabilir. Kültüre özgü karşılaştırmalar hakkında daha fazla bilgi için ad alanına ve Genelleştirme ve Yerelleştirme'ye bakınSystem.Globalization.
