HashSet<T>.IntersectWith(IEnumerable<T>) HashSet<T>.IntersectWith(IEnumerable<T>) HashSet<T>.IntersectWith(IEnumerable<T>) HashSet<T>.IntersectWith(IEnumerable<T>) Method

Definition

Modifies the current HashSet<T> object to contain only elements that are present in that object and in the specified collection.

public:
 virtual void IntersectWith(System::Collections::Generic::IEnumerable<T> ^ other);
[System.Security.SecurityCritical]
public void IntersectWith (System.Collections.Generic.IEnumerable<T> other);
abstract member IntersectWith : seq<'T> -> unit
override this.IntersectWith : seq<'T> -> unit
Public Sub IntersectWith (other As IEnumerable(Of T))

Parameters

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

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

Exceptions

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.
