Uwagi
Każdy klucz musi implementować interfejs, IComparable aby móc porównać każdy inny klucz w SortedList obiekcie. Elementy są sortowane zgodnie z implementacją IComparable każdego klucza dodanego do elementu SortedList.
Pojemność SortedList obiektu jest liczbą elementów, które SortedList mogą być przechowywane. W miarę SortedListdodawania elementów do obiektu pojemność jest automatycznie zwiększana zgodnie z wymaganiami przez przeniesienie tablicy wewnętrznej.
Jeśli można oszacować rozmiar kolekcji, określenie początkowej pojemności eliminuje konieczność wykonywania wielu operacji zmiany rozmiaru podczas dodawania elementów do SortedList obiektu.
Ten konstruktor jest operacją O(1)

Uwagi
Elementy są sortowane zgodnie z określoną IComparer implementacją. comparer
Jeśli parametr ma null
wartość , IComparable jest używana implementacja każdego klucza, dlatego każdy klucz musi zaimplementować IComparable interfejs, aby móc porównać każdy inny klucz w SortedList obiekcie.
Pojemność SortedList obiektu jest liczbą elementów, które SortedList mogą być przechowywane. W miarę SortedListdodawania elementów do obiektu pojemność jest automatycznie zwiększana zgodnie z wymaganiami przez przeniesienie tablicy wewnętrznej.

Uwagi
Każdy klucz musi implementować interfejs, IComparable aby móc porównać każdy inny klucz w SortedList obiekcie. Elementy są sortowane zgodnie z implementacją IComparable każdego klucza dodanego do elementu SortedList.
Obiekt Hashtable jest przykładem implementacji IDictionary , którą można przekazać do tego konstruktora. Nowy SortedList obiekt zawiera kopię kluczy i wartości przechowywanych w obiekcie Hashtable.
Pojemność SortedList obiektu jest liczbą elementów, które SortedList mogą być przechowywane. W miarę SortedListdodawania elementów do obiektu pojemność jest automatycznie zwiększana zgodnie z wymaganiami przez przeniesienie tablicy wewnętrznej.
Jeśli można oszacować rozmiar kolekcji, określenie początkowej pojemności eliminuje konieczność wykonywania wielu operacji zmiany rozmiaru podczas dodawania elementów do SortedList obiektu.
Ten konstruktor jest operacjąO(n)
, gdzie n
jest liczbą elementów w .d

Uwagi
Elementy są sortowane zgodnie z określoną IComparer implementacją. comparer
Jeśli parametr ma null
wartość , IComparable jest używana implementacja każdego klucza, dlatego każdy klucz musi zaimplementować IComparable interfejs, aby móc porównać każdy inny klucz w SortedList obiekcie.
Pojemność SortedList obiektu jest liczbą elementów, które SortedList mogą być przechowywane. W miarę SortedListdodawania elementów do obiektu pojemność jest automatycznie zwiększana zgodnie z wymaganiami przez przeniesienie tablicy wewnętrznej.
Jeśli można oszacować rozmiar kolekcji, określenie początkowej pojemności eliminuje konieczność wykonywania wielu operacji zmiany rozmiaru podczas dodawania elementów do SortedList obiektu.
Ten konstruktor jest operacją O(n)
, gdzie n
to capacity
