[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, considered in order. This is the same notion of equality as in Algorithms.EqualCollections, but encapsulated in an IEqualityComparer<IEnumerable<T>> implementation.

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

IEqualityComparer<IEnumerable<T>> implementation suitable for comparing collections of T for equality.

Type Parameters

T
