Açıklamalar

Anahtar/değer çiftleri, numaralandırıcının Array nesne üzerinden yinelendiği sırada nesneye SortedList kopyalanır.

Yalnızca içindeki SortedListanahtarları kopyalamak için kullanın SortedList.Keys.CopyTo.

Yalnızca içindeki SortedListdeğerleri kopyalamak için kullanın SortedList.Values.CopyTo.

Bu yöntem bir O(n) işlemdir ve burada n şeklindedir Count.
