Definition

public:
 KeyCollection(System::Collections::Generic::Dictionary<TKey, TValue> ^ dictionary);
public KeyCollection (System.Collections.Generic.Dictionary<TKey,TValue> dictionary);
new System.Collections.Generic.Dictionary<'Key, 'Value>.KeyCollection : System.Collections.Generic.Dictionary<'Key, 'Value> -> System.Collections.Generic.Dictionary<'Key, 'Value>.KeyCollection

Remarks

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

This constructor is an O(1) operation.
