Determines whether a SortedSet<T> object is a proper superset of the specified collection.

Namespace:   System.Collections.Generic
Assembly:  System (in System.dll)

public bool IsProperSupersetOf(
	IEnumerable<T> other
)

Parameters

other
Type: System.Collections.Generic.IEnumerable<T>

The collection to compare to the current SortedSet<T> object.

Return Value

Type: System.Boolean

true if the SortedSet<T> object is a proper superset of other; otherwise, false.

Exception Condition
ArgumentNullException

other is null.

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.
