public KeyCollection (System.Collections.Generic.SortedDictionary<TKey,TValue> dictionary);
new System.Collections.Generic.SortedDictionary<'Key, 'Value>.KeyCollection : System.Collections.Generic.SortedDictionary<'Key, 'Value> -> System.Collections.Generic.SortedDictionary<'Key, 'Value>.KeyCollection
Public Sub New (dictionary As SortedDictionary(Of TKey, TValue))

Remarks
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.
