Computes the union of this set with another set. The union of two sets is all items that appear in either or both of the sets. A new set is created with the union 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> Union( Set<T> otherSet )

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

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

Parameters

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

Return Value

The union of the two sets.

Remarks

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

The union of two sets is computed in time O(M + N), where M is the size of the one set, and N is the size of the other set.

Exceptions

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