| AlgorithmsGetCollectionEqualityComparerT Method (IEqualityComparerT) |
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.
An IEqualityComparer<T> is used to determine if individual T's are equal
Namespace: X3Platform.Collections
Assembly: X3Platform.Support (in X3Platform.Support.dll) Version: 1.0.0.0 (2.0.0.0)
Syntaxpublic static IEqualityComparer<IEnumerable<T>> GetCollectionEqualityComparer<T>( IEqualityComparer<T> equalityComparer )
Parameters
- equalityComparer
- Type: System.Collections.GenericIEqualityComparerT
An IEqualityComparer<T> implementation used to compare individual T's.
Type Parameters
- T
[Missing <typeparam name="T"/> documentation for "M:X3Platform.Collections.Algorithms.GetCollectionEqualityComparer``1(System.Collections.Generic.IEqualityComparer{``0})"]
Return Value
Type: IEqualityComparerIEnumerableTIEqualityComparer<IEnumerable<T>> implementation suitable for comparing collections of T for equality.
Examples
The following code creates a Dictionary where the keys are a collection of strings, compared in a case-insensitive way
Dictionary<IEnumerable<string>, int> = new Dictionary<IEnumerable<string>, int>(Algorithms.GetCollectionEqualityComparer<string>(StringComparer.CurrentCultureIgnoreCase));
