SortedSet<T>.IsProperSupersetOf(IEnumerable<T>) SortedSet<T>.IsProperSupersetOf(IEnumerable<T>) SortedSet<T>.IsProperSupersetOf(IEnumerable<T>) SortedSet<T>.IsProperSupersetOf(IEnumerable<T>) Method


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

 virtual bool IsProperSupersetOf(System::Collections::Generic::IEnumerable<T> ^ other);
public bool IsProperSupersetOf (System.Collections.Generic.IEnumerable<T> other);
abstract member IsProperSupersetOf : seq<'T> -> bool
override this.IsProperSupersetOf : seq<'T> -> bool
Public Function IsProperSupersetOf (other As IEnumerable(Of T)) As Boolean


IEnumerable<T> IEnumerable<T> IEnumerable<T> IEnumerable<T>

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


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.
