Poznámky
Každý klíč musí implementovat IComparable rozhraní, aby bylo možné porovnávat všechny ostatní klíče v objektu SortedList . Prvky jsou seřazené podle IComparable implementace každého klíče přidaného SortedListdo .
Kapacita objektu SortedList je počet prvků, které SortedList může obsahovat. Při přidání prvků do objektu SortedListse kapacita automaticky zvýší podle potřeby přerozdělováním interního pole.
Pokud lze velikost kolekce odhadnout, zadáním počáteční kapacity se eliminuje nutnost provádět řadu operací změny velikosti při přidávání prvků do objektu SortedList .
Tento konstruktor je O(1)
operace.

Poznámky
Každý klíč musí implementovat IComparable rozhraní, aby bylo možné porovnávat všechny ostatní klíče v objektu SortedList . Prvky jsou seřazené podle IComparable implementace každého klíče přidaného SortedListdo .
Objekt Hashtable je příkladem IDictionary implementace, která může být předána tomuto konstruktoru. Nový SortedList objekt obsahuje kopii klíčů a hodnot uložených v objektu Hashtable.
Kapacita objektu SortedList je počet prvků, které SortedList může obsahovat. Při přidání prvků do objektu SortedListse kapacita automaticky zvýší podle potřeby přerozdělováním interního pole.
Pokud lze velikost kolekce odhadnout, zadáním počáteční kapacity se eliminuje nutnost provádět řadu operací změny velikosti při přidávání prvků do objektu SortedList .
Tento konstruktor je O(n)
operace, kde n
je počet prvků v d
.

Poznámky
Prvky jsou seřazeny podle zadané IComparer implementace. comparer
Pokud je null
parametr , IComparable použije se implementace každého klíče, proto musí každý klíč implementovat IComparable rozhraní, aby bylo možné provádět porovnání s každým druhým klíčem v objektuSortedList.
Kapacita objektu SortedList je počet prvků, které SortedList může obsahovat. Při přidání prvků do objektu SortedListse kapacita automaticky zvýší podle potřeby přerozdělováním interního pole.
Pokud lze velikost kolekce odhadnout, zadáním počáteční kapacity se eliminuje nutnost provádět řadu operací změny velikosti při přidávání prvků do objektu SortedList .
Tento konstruktor je O(n)
operace, kde n
je capacity

comparer
je null
