SortedSet<T>.IsProperSupersetOf Method (IEnumerable<T>)
Determines whether a SortedSet<T> object is a proper superset of the specified collection.
Assembly: System (in System.dll)
Return ValueType: System.Boolean
true if the SortedSet<T> object is a proper superset of other; otherwise, false.
An empty set is a proper superset of any other collection. Therefore, this method returns true if the collection represented by the other parameter is empty unless the current SortedSet<T> collection is also empty.
This method always returns false if Count is less than or equal to the number of elements in other.
If the collection represented by other is a SortedSet<T> collection with the same equality comparer as the current SortedSet<T> object, this method is an O(n) operation. Otherwise, this method is an O(n + m) operation, where n is the number of elements in other and m is Count.
