OrderedDictionary.GetEnumerator method returns an IDictionaryEnumerator object that iterates through the OrderedDictionary collection.
public virtual System.Collections.IDictionaryEnumerator GetEnumerator ();
Return Value: An IDictionaryEnumerator object for the OrderedDictionary collection.
Below given are some examples to understand the implementation in a better way:
key1 --> value1 key2 --> value2 key3 --> value3 key4 --> value4 key5 --> value5
A --> Apple B --> Banana C --> Cat D --> Dog
- Enumerators can be used to read the data in the collection, but they cannot be used to modify the underlying collection.
- Initially, the enumerator is positioned before the first element in the collection.
- This method is an O(1) operation.
- An enumerator remains valid as long as the collection remains unchanged. If changes are made to the collection, such as adding, modifying, or deleting elements, the enumerator is irrecoverably invalidated and its behavior is undefined.
