Uwagi

Po utworzeniu CaseInsensitiveHashCodeProvider wystąpienia przy użyciu tego konstruktora Thread.CurrentCulture bieżący wątek jest zapisywany. Procedury porównania używają zapisanej kultury do określania reguł wielkości liter; dlatego porównania kodu skrótu mogą mieć różne wyniki w zależności od kultury. Aby uzyskać więcej informacji na temat porównań specyficznych dla kultury, zobacz System.Globalization przestrzeni nazw i globalizacji i lokalizacji.
