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

Definition

Namespace:: System.Collections.Generic

Assembly:: System.Collections.dll

Assembly:: System.dll

Assembly:: netstandard.dll

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

public:
 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

Parameters

other: IEnumerable<T>

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

Returns

Boolean

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

Implements

IsProperSupersetOf(IEnumerable<T>) IsProperSupersetOf(IEnumerable<T>)

Exceptions

ArgumentNullException

other is null.

Remarks

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.
