Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
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>.KeyCollectionPublic 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
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.
