SortedSet<T>.IsSupersetOf Method

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

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

public bool IsSupersetOf(
	IEnumerable<T> 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 superset of other; otherwise, false.




other is null.

All collections, including the empty set, are supersets of the empty set. Therefore, this method returns true if the collection represented by the other parameter is empty, even if the current SortedSet<T> object is empty.

This method always returns false if Count is less than 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.
