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

public:
 KeyCollection(System::Collections::Generic::SortedDictionary<TKey, TValue> ^ dictionary);

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))

Parameters

dictionary: SortedDictionary<TKey,TValue>

The SortedDictionary<TKey,TValue> whose keys are reflected in the new SortedDictionary<TKey,TValue>.KeyCollection.

Exceptions

ArgumentNullException

dictionary is null.

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.
