OrderedDictionary.Clear method is used to remove all elements from the OrderedDictionary collection.
public void Clear ();
Exception: If the OrderedDictionary collection is read-only then it will throw NotSupportedException.
Below given are some examples to understand the implementation in a better way:
Number of elements are : 5 key1 -- value1 key2 -- value2 key3 -- value3 key4 -- value4 key5 -- value5 Number of elements are : 0
Number of elements are : 4 A -- Apple B -- Banana C -- Cat D -- Dog Number of elements are : 0
- After calling the Clear method, the Count property is set to zero.
- References to other objects from elements of the collection are also released.
- The capacity of dictionary is not changed as a result of calling this method.
