SortedDictionary<TKey, TValue>.Clear Method
Removes all elements from the SortedDictionary<TKey, TValue>.
Assemblies: System (in System.dll)
System.Collections (in System.Collections.dll)
The Count property is set to 0, and references to other objects from elements of the collection are also released.
This method is an O(1) operation, since the root of the internal data structures is simply released for garbage collection.
