public ValueCollection (System.Collections.Generic.Dictionary<TKey,TValue> dictionary);

new System.Collections.Generic.Dictionary<'Key, 'Value>.ValueCollection : System.Collections.Generic.Dictionary<'Key, 'Value> -> System.Collections.Generic.Dictionary<'Key, 'Value>.ValueCollection

Remarks

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

This constructor is an O(1) operation.
