KeyedCollection<TKey, TItem>.Dictionary Property
Gets the lookup dictionary of the KeyedCollection<TKey, TItem>.
Assembly: mscorlib (in mscorlib.dll)
By default, the KeyedCollection<TKey, TItem> includes a lookup dictionary that is created when the first item is added. When an item is added to the KeyedCollection<TKey, TItem>, the item's key is extracted once and saved in the lookup dictionary for faster searches. This behavior can be overridden by using the KeyedCollection<TKey, TItem>(IEqualityComparer<TKey>, Int32) constructor and specifying a dictionary creation threshold.
Retrieving the value of this property is an O(1) operation.
