Computes the intersection of this set with another set. The intersection of two sets is all items that appear in both of the sets. A new set is created with the intersection of the sets and is returned. This set and the other set are unchanged.

Namespace: Wintellect.PowerCollections
Assembly: PowerCollections (in PowerCollections.dll)

Syntax

C#
public Set<T> Intersection( Set<T> otherSet )

Visual Basic (Declaration)
Public Function Intersection ( _ otherSet As Set(Of T) _ ) As Set(Of T)

Visual C++
public: Set<T>^ Intersection ( Set<T>^ otherSet )

Parameters

otherSet: Set<(Of <T>)>
Set to intersection with.

Return Value

The intersection of the two sets.

Remarks

When equal items appear in both sets, the intersection will include an arbitrary choice of one of the two equal items.

The intersection of two sets is computed in time O(N), where N is the size of the smaller set.

Exceptions

Exception	Condition
System..::InvalidOperationException	This set and otherSet don't use the same method for comparing items.
