Assembly: System (in system.dll)

Parameters

dictionary

The SortedDictionary whose keys are reflected in the new SortedDictionary.KeyCollection.

Exception typeCondition

ArgumentNullException

dictionary is a null reference (Nothing in Visual Basic).

The SortedDictionary.KeyCollection is not a static copy; instead, the SortedDictionary.KeyCollection refers back to the keys in the original SortedDictionary. Therefore, changes to the SortedDictionary continue to be reflected in the SortedDictionary.KeyCollection.

This constructor is an O(1) operation.
