Public Sub IntersectWith (other As IEnumerable(Of T))

Parameters

other: IEnumerable<T>

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

Implements

IntersectWith(IEnumerable<T>)

Attributes: SecurityCriticalAttribute

Exceptions

ArgumentNullException

other is null.

Remarks

If the collection represented by the other parameter is a HashSet<T> collection with the same equality comparer as the current HashSet<T> object, this method is an O(n) operation. Otherwise, this method is an O(n + m) operation, where n is Count and m is the number of elements in other.
