SortedDictionary<TKey, TValue>.KeyCollection Constructor (SortedDictionary<TKey, TValue>)


The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.

Initializes a new instance of the SortedDictionary<TKey, TValue>.KeyCollection class that reflects the keys in the specified SortedDictionary<TKey, TValue>.

Namespace:   System.Collections.Generic
Assembly:  System (in System.dll)

public KeyCollection(
	SortedDictionary<TKey, TValue> dictionary

Exception Condition

dictionary is null.

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

This constructor is an O(1) operation.
