[This topic is pre-release documentation and is subject to change in future releases. Blank topics are included as placeholders.]

Gets an IEqualityComparer<IEnumerable<T>> implementation that can be used to compare collections of elements (of type T). Two collections of T's are equal if they have the same number of items, and corresponding items are equal, without regard to order. This is the same notion of equality as in Algorithms.EqualSets, but encapsulated in an IEqualityComparer<IEnumerable<T>> implementation.

An IEqualityComparer<T> is used to determine if individual T's are equal

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

Syntax

C#
public static IEqualityComparer<IEnumerable<T>> GetSetEqualityComparer<T>()

Visual Basic (Declaration)
Public Shared Function GetSetEqualityComparer(Of T) As IEqualityComparer(Of IEnumerable(Of T))

Visual C++
public: generic<typename T> static IEqualityComparer<IEnumerable<T>^>^ GetSetEqualityComparer ()

Return Value

IEqualityComparer<IEnumerable<T>> implementation suitable for comparing collections of T for equality, without regard to order.

Type Parameters

T

Examples

The following code creates a Dictionary where the keys are a set of strings, without regard to order

	Copy Code
Dictionary<IEnumerable<string>, int> = new Dictionary<IEnumerable<string>, int>(Algorithms.GetSetEqualityComparer<string>(StringComparer.CurrentCultureIgnoreCase));
